Printer Faults - Skewed Pages

To print skewed a page would have to pass through the registration station at an angle. The general idea of registration is to straighten up any slight feed errors in a pair of pagewidth roller that don't start to move until the print station is ready for a page.

Skewed feeding rather implies the registration station isn't managing to straighten the page - that might be because it is worn, or the paper feed process preceeding it has too much of a problem.

If a page arrives at the print station skewed; it implies:

Paper guides in tray too loose (or possibly too tight).

Uneven wear on feed rollers causing them to push the page to the registration station at an angle.

Another possibility is an obstruction in the feed path that impedes but does not block the paper.

In most printers it would be just about impossible for the optical path or print cartridge to skew a page. If the print cartridge were noticeably misaligned the laser scanner could not write to it and the transfer station could not move the toner. The problem has to be skewing of the paper.

If there is any doubt about how the paper comes to be skewed use a stop test to observe the page when printing is in progress.
