Does not printing or copying ?

This is caused mainly by leaving the Corona Wire sliders anywhere other than where the arrows on the slider meets the arrows on the Drum Units. This leaves solid lines of colour down the length of the page (one per colour with the slider in the wrong place) if it is leaving more than the single line on the page it is probably leaking cartridges. These particular cartridges are known for their ability to leak badly (OEM and Remanufactured cartridges do it). The only option for a leaking cartridge is to replace it and clean out the machine with a lint free cloth preferably a 'Toner Grabber' cloth. If you nee one of the toner grabber cloths then talk to your local cartridge refilling place for one. If they refil toner cartridges there then they probably have them or can suggest a different option.

Try scanning at a lower DPI setting. The machine is only rated to a certain DPI which is how much information it can handle per inch. Lower the DPI the more pixilated an image you get becomes when blown up but unless you are planning on printing 6/4 photos in A3 size then 600-1200 DPI is plenty.

The scanner unit is faulty or the flat harness was not fitted properly to the main board.

There is no such error code. Please check again
