Konica Minolta Bizhub Pro C6501 Error Code C2804
I have encountered error code C2804 with my Konica Minolta Bizhub Pro C6501. It's happening again n again so how to fix it properly.
Have you done any PM lately? what happened before it displayed the error code.
I just had this same code on a 6501, how do your test prints look? If your test prints look good check the color Reg. sensor, cln or replace. Mine ended up being the color Reg Sensor unit. The 2804 refers to black patch error in gamma correction.

Yep, colour reg sensor assembly probably needs a clean.
Also, check that the transfer belt hasn't wandered beacuse this can cause the reg sensors to get pretty filthy.
Thank u all for your kind response after i cln sensors code is not showing now but black print quality is down. It's not like before i mean black color print quality is not good.
Run the colour registration adjustment from the adjustment screen.
Also you can run the recall standard data under process and run all adj. again
