Black background / banding horizontally
I am stumped!!
A customer has brought in a brother dcp-9020cdw, they had put a black toner into the printer without inserting it into the drum first. They can't remember if they closed the top cover but now they are getting this background. They installed a new drum, but still the same. I have verified it is something to do with the black print position. When I install the other colours into the black position they all fail causing the same fault, thus proving the black position.
I have swapped over the black and magenta LED's, problem remains at black.
Checked all contacts and cleaned, reseated HVPS, still the fault remains.
Could the belt unit cause a fault like this?
Any help would be appreciated.
