Why does the print area shift in a laser printer (Xerox 3117)?

Question

Seal

In the above printer, closer to the mileage of 9,000 - 10,000 pages, there was a problem with the print area shifting up the page by 2-4 cm. It turns out that the text is cut off at the top of the page, and there is a large empty space at the bottom.
In this regard, the question is - is this problem common in laser printers in principle and is it solved by replacing the rollers (and which ones)? I can’t think of anything more logical as a reason and solution.
Thank you.

Answer 1

I have exactly the same problem. Moreover, from Mac OS it prints with a shift, but from Windows it is normal.

Answer 2

I don’t know about Xerox, but HP can set shifts of this kind in the tray settings, a parameter may have been set. Make sure paper, guides are set to A4, auto-advance to Letter<->A4 is off. Again, try different versions of the driver, PostScript, PCL5, PCL6.
Does the event log report errors? (if there are problems with the mechanics, then there should obviously be messages about the activation / deactivation of sensors at off-hours)
