Laser Printer not centered

[desy]

So anybody know why a laserjet 5-SI would cut the top of a page off
I mean the printer has shifted the top margin
It was fine and now its not?

Carefully check the driver defaults/settings for changes. The printer should have come with several tests (alignment for one) try running them. May have corrupted the driver - DL the latest, remove the current ones and install the new ones. If that doesn't fix, may need to have the hardware repaired or replaced.
