Re: Overall density is low, white spots on solid pattern - Pro 951
Hello guys again! Today I borrowed Dev. unit (of course developer too) from good working machine, after installing it on problematic machine, I tried to print 100% coverage from service mode, it printed perfectly, but showed error code C2412 and it's clear why, after auto maximum density adjustment, I retried to print 100% coverage and density became lower and engine showed same error code. Definitely Developer is faulty there, but I'm little afraid, what if after replacing developer and dev. unit with new ones, making toner density sensor initial adjustment, density will become low? I'm asking because it's fact that density is very low and machine recognizes it as normal :||
P.S. Before installing borrowed dev. unit, I tried dipswitch 6-7=1, it gave nothing.
