[CQ] Konica-Minolta BH c454 Repeating Marks

[JR Skewing]

My client has a Kon-Min BH c454 with marks repeating at a 156mm interval.
I determined this exact symptom after cleaning the fuser upper/lower pickers and replacing the xfer cleaning blade, which was somewhat worn.
The fuser appears to be in fair condition.
Yes, I am peeling an onion here.
What would cause repeating marks (ghosts) at a 156mm interval?
btw, I only had time to verify this symptom using black, as the client was closing for the day, and I had to vacate the premises.
TIA!

what does the manual say for 156mm repetitive defect?

so you aren't sure if the colors are affected also?

what are the page counts on PM and supplies?

ghosting usually come from fuser/drums

Sounds like fuser. Especially if the rollers were dirty and you cleaned them off. They are probably worn out. BTW.. did any black dust/metal filings fall out of the side when you removed the fuser? The Bearings wear out, if so this would also cause the double image/ghosting
