Hello. I have a C454E with around 60,000 copies. The black density is poor and streaky,
almost like a bad drum. If you run halftones with any othercolor they are fine. Just black
is bad. I swapped the drum and developer units, transfer belt and roller,updated firmware
, swapped memory (never know), and the problem is still there. You can streaks in the copy
count sheet, that are in opposite direction of the paper feed. I have an hv board ordered,
along with a mfp board. Just looking for any suggestions.
Thank for any help
