[CQ] Bizhub 920 duplex print: too light

[ondemandprint]

Bizhub 920 issue.

There is a problem with print quality. While duplex printing from computer: 1st side has a normal density, but 2nd side is much more light.

duplex does second side first first side second. may be damp paper? once it goes through the fuser for the "second side" the paper dries more and the second image (first side) is transferred to paper better.

I have the same problem today with Bizhub 950.
I try good 80gsm paper and its the same.
Interesting is when set paper as 130-160gsm only duplex side print is light on every sheet but when set paper to 80gsm it is much better and 1 of 5 sheets is light.
Drum,developer,coronas,fuser,... is rebult with new parts (not by me),i just get this machine.
Could it be something with transfer assist sheet?

Problem is solved.

57GAR71400 Separating Assembly have been restringed. Strings were too burned and assembly can't maintenance right charge value for the 2nd side as I see. It prevents normal transfer on already charged (after 1st side printed) paper.
