HP LJ 4350 - Print is not centered on page

[thomasp94]

I am running 7 HP LaserJet 4350tn printers, they print on shipping forms with labels at the bottom for UPS. They print through the network from a database server located off site. Lately, on some of the printers the print isn't centered (left to right) on the forms. The print is shifted to the left of the page, this is problem because the forms are pre-printed with columns and the text isn't lining up with the columns, and some of the barcodes are running off the labels. Is it possible that the printers are causing this problem? Perhaps a part that needs replaced? Nothing has been changed in the printer settings, and nothing that I know of has been changed on the server that prints to the printers. Most of the printers are going on 2 million pages so it may just be time to look into getting new ones, but unfortunately I won't be able to do that till next spring. Any help is greatly appreciated as I don't know what to do to correct this problem.

Thanks!

It could be something as simple as the tracking is out, I know people think of cars when you mention the tracking but printers also have a tracking system on the print roller. I had a similar problem to yourself but mine was whilst doing some barcode label printing. Try lifting open the lid and looking at the roller position, you should be able to see if it has moved.

Hope this helps
