The left side is a normal machine, and the right side is a problem machine.
This is chart number 10 on the test page, and it appears as if there is fog.
It's an automatic color correction pattern, but it seems like the 4 colors of black appear as blue.
Things I've tried
4-color drum replacement,
Patch sensor inspection
Developer BK, C replacement
Toner is not provided and the same toner is used as the left pattern machine.

Can you post a pic of PG-10 from service mode please.
Practice makes perfect

Thank you for your answer
This is test page 10.
The middle is the original,
adjust - hv-tr 2tr off
Left is -100
If the right side is + 100.
Is the image on ITB ok?
the sec.transfer roller could be causing problems.
If it's not ok:
Try replacing the dc from another device.

I tried replacing the belt Assy, but the symptom is the same, so I will check DC.
