MX-6070V strange B/W issue.

[BillyCarpenter]

Billy, ALL OEM supplies and parts. Like I've said in 1st post I have replaced MC pwb, K DV unit and drum unit. Still doing the same thing..Ive replaced TC1 and TC2...same thing. Bias is fine through sims but is too quick to get a reading on multi meter as its too fast.

You've eliminated a lot of stuff but you're missing something. Bias may read fine thru sims but have you checked the contacts for the drum & DV? That would make sense to me since you've replaced with new drum & DV units but still getting same results.

EDIT: Use Allan's idea. Stop the print process in time to inspect the drum to see if the image is nice and dark on the drum. If not, there's a good chance you don't have good drum charge or high DV bias voltage.

I just can't assume. If I understand you correctly, it seems your internal prints are good, am i correct? If that is the case and its just copies we may have an issue with the scanner assembly, possibly.

No sir, horrible, please reference photo in 1st post. they looked all pixelized and dark.

UPDATE I found the problem.....just for shits and giggles I reseated the white ribbon cable to the the MFB that goes to the LSU pwb and BOOOOOOM. look beautiful. Thank you guys
