cs-820 intermittent image shift

[yakyitz]

The image will intermittently shift so that the top half of the image is completely missing from the page and the bottom half is shifted to the top half. The customer claims either the whole run is OK or the whole run is not. Originals and copies are landscape. Please see attached sample of original and copy. Of course it didn't happen when I was there. Any ideas? Thanks.
Correction originals/copies are running "portrait" NOT "landscape"

You need to look at your document processor. Under the seperation roller there is a torque limiter (part #22 of the exit section in the parts list). Look at the housing and see if it is cracked, the crack may not be all that large. If it is replace it. If not, clean it. I believe that is your problem.

Zackuth Thanks for your reply. But from your reply I realized I made an important mistake in regards to the direction off the originals/copies. They are running "portrait" NOT "landscape.

Re: cs-820 intermittent image shift

Ok forget what I said earlier. You have a BAD image shift problem. If you look at your copy, you can see a line that refers to the bottom of the original. Make sure the DP guides aren't broke as both top and bottom guide should close to the paper size. If that doesn't work you wil have to go into the maint mode and run the adjustments for scanning positions.

Re: cs-820 intermittent image shift

Oops, I forgot you said intermittent. Your customer might be running portrait but have the machine set to landscape, or A4 or some such. Have you had the customer make copies for you?

She actually is one of those end users who actually knows her machine. I have to check with her to find out what she did in order to continue.

Re: cs-820 intermittent image shift

Just copies, or prints also? I had something somewhat similar ... let's see if I can find it ...

It was on a VoyagerE CS-C4035E: Image registration is late by 137.5 mm (~5") on prints only from all applications. No effect on fax & copies. Tried installing updated driver, but didn't help. Restarted the print card. Press Print Menu, Others, Printer Reset, Yes (do not turn power Off).

Re: cs-820 intermittent image shift

I have once that problem, machine AMS not working properly because switch was dirty ant if i remember that format width limiter have very specific system to detect what format you placed. But first check if you have turn "on" automatic format rotation. probably you have this option of and default original is set to landscape <- this is very often cause (machine show you in screen how is placed original), user change it without know that :P
