      If it makes you feel any better, there are some printers that do actually burn their paper. (More or less.) They use a thermal paper that reacts to heat. Not sure why anyone does this, but there you go. Side note: one huge disadvantage of using a printout from thermal paper is that you can't use a pencil eraser on one because the friction of a rubber eraser generates heat and thus makes black smear marks on thermal paper. Oops. Of course that was many many years ago that I last used one. Maybe they changed?

    Text in the quick scroll at 0:18
    Ink dries out, meaning that the printer has to either constantly be performing a "maintenance mode" which wastes ink, or you need to print rather regularly which, in this paperless age fewer and fewer people are doing.
    The herky-jerky nature of the print heads as they travel back and forth is very unpleasant compared to the smooth print of pretty much any laser printer.
    Ink cartridges are usually priced at stupid levels, meaning that you're forced into buying generic ink which often clogs the inkjects so you're damned if you do, damned if you don't.
    Because the ink is a liquid, freshly printed documents have a tendency to smear if touched until the ink has dried.
    Water-based inks are likely to completely wash away if the paper they are printed onto becomes wet, meaning shipping labels printed with some inkjet printers can be rendered completely unreadable if they get wet from something like, oh I don't know, rain.
    None of these issues plague laser printers, so despite their higher upfront cost (and arguably more expensive toner) you can pretty much count on them to work perfectly even if they've been idle for over a year, they don't waste toner on "maintenance modes", the toner is bonded to the paper so water doesn't smear it, the toner is never wet so you don't have to wait for it to dry, plus spills can easily be cleaned up as the toner is a powder. I could go on but if you read this entire thing, now you know why I generally dislike inkjet printers and why I will forever use laser printers. Or LED printers, which are the suspect of this video and you'll soon see.
    That said, Techmoan recently reviewed[0] an inkjet printer that was actually pretty decent in terms of the ink cost, so even if a "maintenance mode" were to waste ink, it's not like it's wasting super expensive ink.
    Perhaps one day I'll rejoin Team Inkjet. Particularly for photo printing (and images in general) inkjet remains supreme. But for now, I'm planted in the realm of toner so that, when I have to do my taxes, I don't have to waste time, energy, and money fighting a stupid inkjet with clogged heads.

      Inkjets are commonly used for direct to garment printers. Especially their 60+ inch wide variety. As well as direct to canvas as a Giclee substitute, used for on-demand printing of optical discs and case art, pigmented inks with 100 or more years of fade resistance can be found in Epson's home printers with their DuraBright CMYK inks.

    You, my good Sir, have just helped me solve a Problem that has haunted me for at least the last year! After many toner cartridge and toner drum swaps, my printer still printed either very thin or extremely blurry around fine details. I cleaned the toner drum and fixing unit with rubbing alcohol but nothing helped. After watching this fine example of audio-visual excellence, I went to look for this fine row of LEDs and after a quick cleanup with rubbing alcohol, the prints are crisp, sharp and as new! You have just saved me from buying a new printer. Consider me as a part of your notification squad!

    I actually work on printers and copy machines, more often than not, a lot of the newer printers that are manufactured seem to be using LEDs over laser, I even work on some machines that use a hybrid of both laser and led. Laser is generally about as reliable as LED from my experience, the "spinny thing" you referred to in the laser unit is called a polygon mirror motor, after a certain time these will get stuck or not spin as fast causing failure. I've yet to have an actual laser or led die on machines I work on and some of them push over 1 million copies/prints in months. The only real advantage to a laser only setup I could see is the resolution and the lack of toner getting on the laser blocking portions of the print. LED only printers have the downside of toner generally will spill on the LEDs and block light. Also it's worth mentioning not a lot of newer machines and depending on the manufacturer don't use corona wire anymore, they use something called a charge/development/magnetic roller, terminology varies per manufacturer and there's normally an upper and lower looks like the one in your video have a roller from what I saw.
    Hope my knowledge helps! Great video!

    • @johngeannaris2470
      @johngeannaris2470 6 ปีที่แล้ว +32

      fellow print wizard here and can concur that laser and led have about the same level of reliability. So many other parts are going to wear out so much sooner than the laser mirror that outside of a print-shop or heavier environment, its pretty much a non issue.
      what i want to bring up is that samsung that was used in the video and the reason it is that much slower to print color. now the reason is not that it is laser vs led, its that the machine appears to not use a primary/secondary (belt) transfer system but transfer directly from the developer roller to a single large photo conducting drum. from the look of it, it must do a pass for each of the colors waiting for the 4th pass to run the paper past for transfer and then clean the pc drum. not necessarily a bad system, its just trading speed for less expensive consumables.
      but enough about drums and charging, lets talk about the real hot topic. the move away from heating fusers via incandescence to sexy sexy induction heating.

      Have yet to have an actual laser or led die on machines you work on?? What magic fairy dust are you sprinkling on them? The polygon mirror is the most common failure, but I had a couple of LED arrays with a partial failure leaving blank lines. Some laser diode failures also, normally a code for no beam detect when the polygon mirror spins freely.

      Shall I bring up the time in the 1980s when I had a copier with both a thermistor failure and a thermal fuse failure so that the halogen lamp stayed on until the aluminum heat roller melted to a puddle into the silicon oil pan under the press roller? It was a Mita DC-312RE as I recall. The customer phoned it in as "smelled hot". There was fire extinguisher residue all over the machine.

  • @TechnologyConnections
    @TechnologyConnections  6 ปีที่แล้ว +492

    One minor footnote: Usually (if not always) in laser and LED printers, the polarity of the toner is reversed from my explanation. Parts of the drum that receive light attract toner, and dark portions do not. Rather frustratingly, I can't find where I had read this (pretty sure it was just on everyone's favorite source of knowledge, but visiting my recent pages and some Ctrl-effing hasn't helped). If my unreliable memory is correct, this reduced wasted toner because it allowed for stronger repelling of toner in the unexposed parts of the drum. Or something like that.

    • @TheWilldrick
      @TheWilldrick 6 ปีที่แล้ว +22

      I have a similar printer (3150CDN) and all I can say is the most reliable printer I ever had. It never jams, never out of ink mid-job, it can print in long batches or be left unused for months to come back and print perfectly. The quality still is not on par with an inkjet, but for documents you can't beat it.
      I noticed your toner holders and cartridges are kinda messy, are you rechargin yours or using alternative ones? if so, how's your print quality and does it damage the imaging unit?

    • @TechnologyConnections
      @TechnologyConnections  6 ปีที่แล้ว +46

      Well, I've inherited this printer from my parents who wanted an all-in-one for copying and scanning. From day one it's been using generic toner replacements, and some years ago there was a bad batch of cartridges that leaked everywhere. In recent years the availability of decent generics has much improved, in fact a good full set (plus an extra K cartridge) runs around $60 on Amazon.
      And indeed, this printer has been very very reliable. The only bummers are that this model doesn't do duplexing, and that it takes a while to warm up. Recent laser printers can warm up in something like 6 seconds which is awesome! I have a newer basic B+W printer (also a Brother, though I think it actually is a laser printer) that does auto-duplex and warms up much faster, so the HL-3040CN stays idle unless I need color. Which is quite rare.
      Honestly it's pretty much a spare at this point. But a very good spare!

    • @zaprodk
      @zaprodk 6 ปีที่แล้ว +24

      The new printers use a different method of fixing the toner. The good old ones used a large halogen bulb inside a teflon-coated aluminum tube. The paper was squeezed against this tube and a soft, flexible silicone-roller. In the new printers the heating is done by a thick-film heater - a ceramic substrate made from Alumina (Aluminum oxide) has a deposited track of resistive material on it. Over this heating element there is a spinning loop (tube) of what seems identical to the reusable teflon cooking sheets we use in our oven. The paper is squeezed against this loop and a soft, flexible silicone-roller. There is almost no thermal mass to heat up, so the fixer is ready in an instant!

      LED printers are still laser cause of the led being used if you look in to fibre optic communications most modern fibre optic communications uses a LED laser for the light component and not a traditional laser, even in CD players you will find it is an LED laser as it’s light source, so still a laser. So the LED printer uses an LED lasers have a look at the Bluray laser diode that is also still an LED as it’s a diode. Pays to look into things a bit more closer Alec.

    Another advantage to the Brother-style setup is that you can have a fully straight paper path using the manual input tray and the back door that bypasses the roller that flips the page over and out the top, letting you print on thicker paper that would otherwise jam or curl too much, or on labels that would otherwise have the possibility of peeling off inside the mechanism.

      I actually loved working on printers, especially laser/ LED printers, as the lion's share of the problems were mechanical in nature, not electronic, or even software in nature. They were frequently easy to correct, but you had to have parts on hand to fix them. HP's being the most popular when I was doing computer work, were the most popular lasers, and Okidata was the most popular dot matix. Keeping some denatured alcohol, a couple of fusers, pickup rollers and a printhead or two on hand, and I could bang out several easy, high-profit printer service calls in a day!

A favourite thing about these vs. inkjets: You can go a month between prints and it comes out perfect the first time. Downside: It repeatedly warns that toner is low months before it actually quits working due to low toner.

      I've been fooling mine for around five years and it's done over 10k pages on the stock sampler cartridges with no picture quality issues whatsoever. Maybe I just got lucky and they ran out of sampler carts at the factory, reprogrammed the EEPROM in some regular ones to report only 1k page capacities, sold them as samplers, and called it a day. Or maybe all sampler cartridges are like this. Who knows.

      I have a Brother color "all in one" that is an LED printer. The "Toner Low" warning it TOTALLY BOGUS! In addition to coming on far too early, it counts copies ONLY without regard to whether they are color. As a result, it will start demanding replacement color cartridges even if you never run color copies. Fortunately, the counters can be reset from the printer control panel. Google the model number of your printer and "toner reset" or something similar to get directions.
      I was very confused the first time I opened my new "Laser Printer" and found the line of LED bars and drums. It didn't take too long to figure out what it was, but it totally blew my mind that I had never heard of the technology.
      I'm seeing several comments that the print quality of LED printers is sub par and can only say I find the quality just fine! It's definitely better than my eyesight! LOL

  • @Iceflkn

    I was a color copier technician for 28 years and mostly worked on the Canon line. The very first model I worked on was the Canon CLC 200 series.
    I also repaired typewriters, fax machines, shredders, electric printing calculators and almost every other kind of office equipment commonly used in the mid 1980's.
    Of course, this included several makes and models of printers. Ink plotters, ink jet as well as toner types, both black and white and full color.
    One of the most unique printers I have worked on was the full color thermal printer.
    They had 4 colors of plastic film with a multi-element thermal print head for each color (C, Y, M, Bk). They then, "burned" each one in layers to reproduce the image. So there was no need for a drum, no led array nor any laser assemblies of any kind. Another advantage these machines had was not needing a fusing unit.
    These machines were considerably more quiet to operate than the others. The lack of a fusing unit meant it would not heat up the room. No corona wires meant there would be no unpleasant ozone scent would be filling up a room.
    Unfortunately, this type was quite a bit slower and the films frequently jammed or tore. The yield of how many pages could be printed per roll was also, quite low. This made the cost per page considerably higher when compared to other methods. Also, the rolls of film were rather large, making the "footprint" or the copier larger than most.
    These issues, in my opinion, spelled their doom when compared to the other methods and full color thermal printers fell by the way side, disappearing altogether rather fast.
    I am not even certain if they are still available at all today but I'd love to see you do a video on these!
    *One curious quirk to laser printers/copiers that stood out to me was when trying to create a picture frame that hugged the outer edges of the paper. Instead of a nice squared set of corners and straight horizontal lines, it would be crooked.
    This occurred because it was impossible for the spinning mirror to guide a laser beam from one side of the drum, across its entire length, to reach the other side before the drum made some rotation.
    Basically, a straight, full length horizontal line, is impossible to create using a laser and spinning mirror. Optical, Ink, LED and thermal methods did not have this problem.

      I also was a copier/fax/network service tech for Canon, Toshiba, and Ricoh but I worked in Canada. Do you remember the very first Canon colour (Canadian spelling) copier. I believe it was called the CLC 1? I was one of the first to be trained on it in Canada. The drum diameter was the size of a basketball and had no black toner. The blacks were a combo of yellow, cyan, and magenta and would result in blacks that looked more like dark brown. This first colour copier was also the only one that was totally analog. This beast was larger than a household freezer! I remember the CLC 200 and the CLC 500/550. Very nice machines.
      Not mentioned in the video is the reason the Laser printers are much slower with colour than black and white printing. With LED printing the paper passes the LEDs/drums/developers once, no diference with the paper path for either. In a Laser printer, the paper has to pass the optic section once for each colour or 4 times around the drum/charging/developing area. Now-a-days a copier is nothing more than a printer with a built-in scanner unit. Do you remember when copiers used liquid toner?
      Led printers work basically the same as a fax machine.

When I asked IT why we had the LED printers at all, they told me, "Price." Apparently they were much cheaper. But they gave similar results (for documents anyway) and I thought, "Hey, nifty." Now today we have much better LEDs. And it would seem, at least in color printers, they have an advantage. Neat!

It probably has more to do with the specific manufacturer and model of our printers, but they were a maintenance nightmare. VERY sensitive to humidity levels, and I spent a lot of time breaking the image drums loose when they’d jam with bits of label or clumped toner.

    You are just wrong about paper path.. Your LED printer uses a transfer belt (as seen around 6:47 mark black shiny thing), paper never actually touches any of the CMYK photoconductors... Rest of the printer works as you describe, but toner is transferred to the intermediary transfer belt below them not to the paper... Paper itself just makes a L turn at bottom, touches the transfer belt while going up, then it passes through the fuser and gets out on the top... How do I know?? Its the exact same proven setup for any *proper* home/office laser printer including what I own (CS-310DN)... As such, those printers have exactly the same color and grayscale print speeds... Today, only the cheap (read: garbage) color lasers actually have longer and more complex paper paths for color printing...
    From experience (with few printers I've owned in the past) transfer belt provides several advanages; a) on my older printer without transfer belt, any tiny little problem with paper feed on such a long&curved path will make colors all mixed up so it was not only slow but also highly unreliable as printer ages... b) the transfer belt also prevents dust/dirt stuck on paper from damaging the photoconductors, as belt is continuously cleaned by a rubber blade before touching the photoconductors... c) belt also speeds up the printing by seperating paper feed and rasterization processes, printer can start drawing image to the transfer belt well before moving the paper.

      HPs 2500 series had the toners on a drum. Each one rotated into position to transfer its color to the belt in 4 passes. Then the paper would be run through. Four times as long as black. But if you didn't specify to print in greyscale so it'd rotate to black only it would cycle all 4 and increment their page counters while taking as long as a full color page. What was the first color laser to put the toners in a row to do simultaneous overlapping transfer to the belt or directly to the paper?

    I find myself endlessly fascinated and indeed shocked that simple concepts like this in tech always seem to manage to scale down, or up, to such small sizes, efficiencies, and volume. The idea that you can electrically charge a region of paper, transfer toner to it and melt it to create SOMETHING in the way of an image doesn’t seem surprising. The fact that these regions of charge can be scaled down to 600dpi at the speeds of modern printing is really quite astounding. I find myself likewise continually amazed that we have managed to scale down so many other simple concepts to mind blowing levels of detail and efficiency. Reminds me of the late Richard Feynman quote “there’s plenty of room at the bottom”. Of course he was speaking of the subatomic but the metaphor holds that our simple human intuition breaks down beyond anything smaller than we can easily visually perceive.

    Also "laser" printers that do color at 1/4 the b&w speed (or less) usually do so because they are actually printing 4 times, rotating which color is currently printed.

    It's not really on topic, but as you mentioned in your gigantic scrolling text, there are now some inkjets with reasonable ink cost. Because they are fitted from the factory with a continuous ink supply system, where you fill ink tanks and the heads are fixed (or somewhat fixed, HPs still can have the heads replaced).
    Those models are sold at a higher upfront price because the ink is sold at a cheaper price and seem to me a better fit for home use and small office use than a laser printer, but your mileage may vary

    • @superdau
      @superdau 6 ปีที่แล้ว +3

      I have seen two of those printers that were "dead" because the ink in the hoses connecting the tanks to the print heads clogged with gooey ink. So instead of just dried shut nozzles in the print head there's also the additional problem of piping to fail. Their per print cost is lower than the "payed by ink" printers, but I guess you have to print a lot to keep them going. Personally for me there's no way I'll ever go back to ink jets again after having a laser printer.

    • @evefavretto
      @evefavretto 6 ปีที่แล้ว +4

      Clogging is probably going to be a worse issue than with regular cartridge inkjets. And to make matters worse, I think some of the mechanisms are based on regular inkjets with some tubing and a tank slapped on the side. At least the first Epson EcoTanks and HP GT series looks like that: an existing model that they slapped the CISS onto.
      But for people with regular printing, that require color or photo prints, they may make sense. And around here they are cheaper than a color laser.

In the time of the original LaserJet through the III series, they were all built to a high standard, able to last through at least a million pages. I've seen one IIId with over three million pages on its counter. The 4 series continued that trend. Just saw one last week in use at a funeral parlor. But HP introduced the L line same time as the 4. The 4L has nothing in common with the 4 aside from the LaserJet name. It and the 5L and 6L are tiny and slow. Their toner capacity is tiny and price per page high. There have been more cheap laser printers like those while the more durable "tanks" are rarer and not built for millions of pages.

    Early Xerox machines looked like enormous bellows cameras. Back then xerography was a manual process more akin to photography, with the toner being dusted by hand onto a flat surface instead of an motorized drum. This type of Xerox machine was a staple of the animation industry for many years. By replacing the tedious process of hand tracing pencil drawings with ink it speeded up and reduced the cost of traditional cel animation. That's why Hanna-Barbera cartoons from 1968's onward list a Xerographer in the credits.

      Where I work we used to have some huge old Xerox copiers which took a photo of the document to copy it -- instead of a green scanner thing going back and forth across the page, you just saw a single strobe flash. Those were the last "analog" copiers we had, before everything was replaced with digital copiers which are really just a scanner permanently attached to a laser printer.
      One of the Xerox service techs told us that back in the 1960s, Xerox copiers came with a fire extinguisher because the temperature in the fuser was so high that there was a risk of a paper jam catching on fire.

    I am sick to the teeeth of researching printers - then I found YOU! So eloquent in your technical knowledge, then there's the 'spinning thing'...so hi-tech! You had me chuckling more than once and I really enjoyed it!
    Anyhoo, back to the grind. Been researching printers for 3 days now. My quest? To find a decent, small or compact, reasonably priced, colour, laser printer.
    Print speed is not an issue for me nor do I expect to produce hi-quality limited editions or works of art. I want it for mainly for arty-farty stuff including printing on a variety of papers and surfaces for use in mixed media art projects. The techniques I want to try all require a laser printer, hence my quest.
    I already have a Brother print/scan/copy inkjet which I will keep, but it's no good for what I want to do. Has to be laser. I've always used Brother so I am familiar with their printers & they have never let me down.
    Then this LED thing kept cropping up. Brother have a few that peaked my interest but before I commit to a purchase, I really must know this: is the end result, the finished print, exactly the same as a laser print? I mean. does the difference between Laser and LED lie only in how the toner is 'transferred' onto a surface?
    I know, I know. You probably already explained but it would mean so much and make me very happy if you would confirm this! I'd really appreciate your input and expert advice.
    On saying that, I don't really expect a reply coz it's been a few years since you uploaded this but I had to reach out. I had to try.

    Reasons that he doesn't like ink-jet printers:
    -Ink dries out, meaning that the printer needs to either constantly be preforming a "maintenance mode" which wastes ink, or you need to print rather frequently which, in this paperless age, fewer people are doing.
    The herky-jerky nature of the print heads as they travel back and forth is very unpleasant compared to the smooth print of pretty much any laser printer.
    -ink cartridges are usually priced at stupid levels, meaning that you're forced into bbuying generic ink which often clogs the inkjets so you're damned if you do, damned if you don't
    -Because the ink is liquid, freshly printed documents have a tendency to smear if touched until the ink is dried.
    -Water-based inks are likley to completely wash away if the paper they are printed on becomes wet meaning shipping labels printed on some inkjet printers can be rendered completly unreadable if they get wet from something like, oh I don't know, rain.

      Canon inkjets don't have most of those issues, especially not "maintenance" pissing away the ink. Canon printheads are easily removable so in the very rare event they clog they can be soaked in rubbing alcohol overnight. A cleaning cycle or two has them working again. It takes a long time idle for a Canon head to dry up when unused, more than a year if tanks with ink are left in.

HP claimed the ink was "recycled" but that was BS. More than once when a tank was almost out when I'd turned it off suddenly was conveniently empty the next time I turned it on and it just had to do "maintenance" again.

    Perhaps one day I'll rejoin Team Inkjet. Particularly for photo printing (and images in general) inkjet reigns supreme. But for now, I'm planted in the realm of toner so that, when I have to do my taxes, I don't have to waste time, energy, and money fighting the stupid inkjet with clogged heads.

    I enjoy your technical talks. This one hit home. I worked for Xerox and a couple of other mom & pop shops as a Copier repair technician. So allow me to point out some trivial things. I say trivial because they really don't matter to the end user, but make a big deal to us techs that troubleshoot and repair them.
    The first, in your description of how the image is formed on the drum, is missing a little bit of info. Again, this only really matters if you need to troubleshoot the image quality. Some of the imaging systems will use the laser to erase the charge for the toner to get attracted to the drum. We refer to this as 'write black' as in writing black to the drum. Which was the method you described. The other method is 'Write White'. In this method the laser clears away the charge on all of the area where the toner will not stick. So basically the laser is writing to the drum as if it were a negative of the actual image.
    The other thing was how the color image is transferred. On the machine you had, when you pull out a drum, you will see a conveyor belt below all the drums. This is called a 'image transfer belt' or 'ITB' (often we just called it the ITB or transfer belt). This is used to transfer the complete image at once before getting to the paper. The paper never touches the drums. The drums transfer the image to the ITB, which once completed can be transferred to the paper.
    Some color machines do not use the ITB method, but instead send the paper around the machine up to four times, to get the image on the paper. Sending it once around the machine for each drum to be used. The drums on some of these machines would be on a carousel, and be rotated after its image is transferred to the paper, and the the next one gets a go at it, before it then gets sent on to the fuser.
    Again, this stuff doesn't matter to the end user. But to us techs, it means a lot. Especially when you need to fix things. (especially when the customer breaks these things by using the wrong kind of paper, or paper that is stale. Yep, paper past its shelf life).

I don't use the term LED printer with anyone outside the trade, because they wouldn't know what I was talking about. To the layman they are all "laser printers". One interesting thing between the old analog copiers and the modern digital (laser/LED) printers is that the polarity is backwards between them. Had a customer once with an old analog copier and a newer digital one where the toner cartridge wasn't quite different enough. They put the analog toner into the digital machine and made a huge mess.

  • @QuakeGamerROTMG
    @QuakeGamerROTMG 4 ปีที่แล้ว

    I work for Fuji Xerox in Australia working mainly on office printers and I've never really thought about it much since I'm not the one using the printers, I'm the one fixing them, but every single colour printer I've worked on has had an intermediate transfer belt between the drums and page.
    Basically all four drums write their image onto the transfer belt as the belt rotates (if you stop the printer mid operation and look at the belt you can see the fully formed image) and then the page runs up against the belt where a magnetic transfer roller pulls the full image onto the page all at once.
    Whether the image is in colour or black and white the process should be exactly the same, I've looked through a manual for one of the models I work on and it seems to be saying that the transfer belt does a single pass of all four drums and the image is drawn all at once. This would mean there should be no difference between black and white vs colour printing, the colour drums simply have no image drawn to them at the start.
    Where you do see a difference is in the colour vs black and white models of the same printer, a black and white printer only has one drum so no transfer belt is needed, just pull the image from the drum to the page.
    You can see the LED printer in the video has this same setup or at least very similar, you can see the black transfer belt underneath where the drums sit at 6:45 or a close up at 5:44
    One thing I will say is that reliability aside these LED strips would probably be a lot easier to replace than a laser unit and be much less likely to be damaged in transit. The laser is pretty bulky and fragile and is buried deep inside the printer so they are a pain to replace on most models, though it is far from the hardest repair.

My favorite example: Something that discusses...solid ink? Most people aren't familiar with these things. These printers appear to use ....crayons, rather than tonor. The claimed print speed is surprisingly competitive, compared with laser printers. The cost is (almost) on par with color lasers, and the output is just ....(invariably glossy) cool. The inner-workings, along with the history of the tech is potentially a cool story. No complaints - at ALL, just...sayin (giving unsolicited advice), so of course - ignore without concern. But darnit - these are basically printing with crayons, which is funny and cool: (one example) The ColorQube 8580.

    back in the 90's I had a Okidata (i don't know when they shortened it to OKI) LED printer, it was fantastic for a couple reasons, back then I was in the Navy and I was in charge of my ships news letter which I printed on my Okidata, they were usually 7 to 8 pages and I was making 70 copies every month. My unit came with 2 meg ram, I added 16 meg for 18 meg total so no matter how complex the image it printed just fine with no errors. Best of all the toner cartridge was separate from the image drum, and the toner was about 10 or 15 dollars, and I might replace 5 or 8 of them before there was any issue with the drum and replace it. this made the operation cost so much cheaper the say a comparable HP laser printer at the time which I think was either the model II or the III. Added bonus I had a page scanner that had a parallel port pass through and connected to the printer I could make copies without the computer even connected. As time went on eventually I got newer printers and scanners and such and gave the Okidata and scanner to my dad who used it until he retired in 2006, sadly after that it went to goodwill i believe.

      yes, they are usually cheaper than laser printers, but often produce prints of lower quality, and the fact that the toner and drum are usually put into the same cartridge means toner cartridges are more expensive than printers with separate toners, drums and fusers. You usually don't need to replace the drum with every toner cartridge replacement. The same thing can be said for those cheap-ass inkjet printers like that +-50 $ hp printers. they are cheap because they don't have print heads. In those printers the printhead is a part of every ink cartridge (making those cartridges even more expensive)

      I intend to buy a mid level Epson inkjet with EcoTank to test it out. But I believe the ink for ecotank printer's isn't that higher quality pigment-based ink, but rather dye-based. Also those new HP laser jet pro color printers intrigue me.

      I noticed you say this in another comment--the drum and toner cartridges are separate on the printer featured here. Whether or not a manufacturer integrates the drum into the toner cartridge has nothing to do with it being LED vs. laser. In fact both of the printers that I have experience with which used a combined toner and drum replacement cartridge were - you guessed it - laser.

      HP has always bundled the drum with the toner cartridge, even on the original black and white LaserJet.

      Many low cost "lasers" are actually LED. The Dell c1760nw, which often goes for as little as $70, is a popular color "laser" that uses LEDs. Quality is not as good, but for a second or third printer, it does not matter.

    A rule of thumb is that LED printers are in the range below 24ppm. This is limit is created by the time the LED requires to get dim again, while a laser is just manouvered by the prism and has shorter on-off response.

    Transfer belt unit, used in color printing process. Paper does not come in contact with the drums in these units. Instead the color is created on the transfer belt first and then applied to the paper. My research on your LED printer shows that your printer, also has a transfer belt.
    The laser printer uses a polygon mirror which allows the smooth transition of the laser from left to right, This does add a bit more size to the laser component but the LED strip for each color could result in failed LEDs in the strip, requiring the entire strip to be replaced to correct it. LED strips are also used in scanning, but they are also measured for intensity across the array. To guarantee that there are no areas brighter or darker.
    I do like the LED printers, and I believe that in the future, they will become part of a tonerless system. That also utilizes UV instead of a fusing unit.

    Thank you for clearing up why when I've stripped some printers in the past I never managed to find a laser diode anywhere inside a 'laser' printer.
    There never was one to find!

    Speaking of laser printers I recently realized that I worked on the worlds first laser printer. Xerox of course held the patents on the xerographic process used in copiers but strangely IBM beat Xerox to the market on the laser printer by several months. The first such printer installed in a customer environment, there were naturally some engineering models before then, but the first laser printer in the real world was installed at the F.W. Woolworth data center in Milwaukee in 1976. I worked on that printer many, many times but it wasn't till just a couple years ago that I realized that was the first laser printer ever installed in a customer environment.

    Brother has to be the best printer brand out there. I owned a lot of brother products. I can say one thing for that Samsung printer. It’s pretty damn quick, but one flaw I’ve seen in it is photo printing. I’ve always had to lighten the photos up almost drastically when I print or the photos come out dark.
