Parallel Port Service Check - Lexmark T520 Service Manual

Infoprint 1120 and 1125
Multipurpose Tray
Paper fails to feed from the multipurpose tray.
The pick roll should make one complete revolution and stop with the
flat side down. If the pick roll turns but does not pick paper, check
the roll for signs of wear, oil or grease on the surface of the pick roll
or slick spots. If you find a problem, replace the pick roll assembly.
Check to ensure the media that is being fed through the
multipurpose tray assembly meets recommended paper
specifications.

Parallel Port Service Check

Run the "Parallel Wrap Test" on page
Note: The Parallel Wrap Test is designed to check the parallel port
hardware by using a wrap plug (P/N 1319128) and invoking the
Parallel Diagnostic Test. This test helps isolate the printer from the
parallel cable and host. The test provides failure information on the
display for approximately three seconds. If the test indicates that a
problem is detected, replace the controller board.
