Margins being cut off on HP LJ 5si

Every 2 out of 10 pages the the margin moves over to the right and cuts off some of the text

I have done the paper path test from all trays, no success

The printer is a HP Laserjet 5si with the 2000 sheet feeder. It doesn't matter from what tray this happens on, it still cuts off the printing on about 20% of all pages printed

Any ideas?

Thanks

Any chance you could scan an example and post it?

If not no biggy, most likely it's the registration assembly. You have to remove the transfer roller to get to the two front screws and then there are two holding the back down, but they are in plain sight.

Have you also tried it with the manual feed tray? If it still does it on the paper path test from the manual feed it's definitely the registration assembly.
