Washed Magenta Color on Bizhub C220

[norbert_farkas]

Hello,

Any suggestions for the following problem? (image attached).
Drum unit was replaced last week, toner is more then 70%.
It`s doing this only on Magenta color, all the rest of the colors are printing fine. Thank you.

M drum replaced?
looks like classic developer failure

what is the life left on M dev unit?

really give us page count ( life left ) on all supplies/parts

OEM supplies?

Most likely drum M was heavy damaged and over life before replacement?

Thanks Brother.. 'prec the back up

OK I know some don't like my preaching...

LET's get back to BASIC theory...
yes drum cause voids... marks.. usually ACROSS the page ( depending LEF SEF)
BELTS voids in same pattern
DEVs in all my YEARS ( unless drum scratched then different MM spacing in defect ) will display many other but ONLY DIAGONAL voids

Yes I have been wrong ( God.. too many times ) BUT Xerography is the basic same thru all LASER BASED life forms...

Remove the dev tank and you will find your missing developer to be missing.
Probably due to overrun parts and crap toner.

Replace the dev tank. Or the developer and the chip if you know how.
