household glass cleaner and a dry, lint-free cloth to clean the glass.
If the problem with the printer is not fixed by one of these
troubleshooting methods, call your authorized service
representative or the Printronix Customer Solutions Center.

minimum distance of 1/2 inch or 20 times
the minimum element width, whichever is
