Bizhub 758 Light prints

[slytukana]

I am experiencing a light print on bizhub change drum and developer still the same.

When printing on double sided one side is printing well while the other side is light. Single sided all prints are light try changing paper but still same.
Appreciate your help

Re: Bizhub 758 Light prints

Could be a transfer problem. Secondary or primary. Would lean toward secondary with one side being better than the other.
Stop the print mid cycle and check the density of the image on the transfer belt.
If the image is light on the transfer belt then pull the drum mid print and check the density on the drum.

But the IDS value could also indicate where the issue lies.
Play with the transfer voltage values in service mode to see if tat helps.
Any P-codes?

Could be bad contacts to the transfer roller, ITBU or a bad HV board.
