Xerox DC12 - image shift

[JimmyB]

on Xerox DC12

When printing from tray 5 image is shift 2mm in back side as on picture.

any advice?

Did you do a tray alignment for Tray 5.

Shift dosent happen just for one side. There must be 1 mm shift when you print the 1st side.

If tray alignment dosent work it could be 2nd BTR.

i have done tray 5 alignment, of course.
Actually, the shift is about 1 mm, but when print on both side (manual duplex), there is shift about 2-2.5 mm.
this happend on random pages.

i guess, that problem is in 1st BTR on registration rolls or sensor??
or probably some rolls in tray 5 is wear

I'd say send a PM to Milo Wilson and ask....but it sounds to me like you are on the right track.

yup thats where you should be looking . but remembe 2mm tolerance is what's the tolerance for DC12 back to back registration as per Xerox tech here.

[JimmyB]

After made maintenance on 1st BTR and adjust it, the problem is solved

now shift is 0-0.3 mm and on most of prints is almost 0mm.
When printing on both sides (manual duplex on Tray 5) shift between duplex prints is less that 1 mm

I cant agree for 2mm shift .... probably on ExtraHeavy paper, could be on some sheets of course.

if you have shift more that 1 mm, have to looking for service

Thanks for all guys
