Ricoh SP C250DN Laser Printer Toner Refill 理光激光打印机灌粉

Ricoh SP C250DN Laser Printer has a good quality of printing. Just the toner cartridge is pricy. I used to refill the toners a few times, but the roller of the black toner was damaged. So I decide to refill the C, M, Y toner and replace the black cartridge.

理光SP C250DN激光打印机的打印质量很好，只是好彩的价格太贵。我曾经灌过几次粉，可这回黑色的定影辊到寿命了。我决定更换整个黑色硒鼓，再继续给其它三色灌粉。
