Hi! In this video I'll show you how to fix the error "Print Unable E9" on the Brother MFC-L6800DW/6900DW/6950DW/6970DW, and the DCP-6600DW.
The part I replaced is the NFC PCB, code: D012X8011

My Brother MFC-L9550CDW when initially started does not give any error message, and can be instructed to print or copy any number of documents which it does flawlessly. If I then try to perform a further function, it returns "Print Unable Error E9". If I then switch off then restart it, the same thing happens. There is no evidence of paper jamming, and I have thoroughly blasted it out with compressed air. It has done 32750 print copies. Do you have any suggestions for me please? Thankyou, Richard.
