Solution
The head gap may not be set correctly. Try moving the headgap lever
to a lower setting. If that doesn't help, the printhead may be
damaged; call for service.
Problem
The ALARM light is flashing.
Solution
Try turning the printer OFF and then back ON again. If the light still
blinks, call for service.
Problem
The Print Quality and Character Pitch keys on the front panel don't
work.
Solution
The Operator Panel Function in the printer menu can be used to
disable these buttons (Limited Function). If the printer is part of a
customized system or if it is used by a number of people, the system
manager may have used this option to make sure the printer is always
set properly.
Check with your system manager before changing any menu settings.
Problem
My printer keeps indicating "Paper out" when there is paper installed.
Solution
The most likely cause is that the paper sensor groove in the platen is
not being covered by paper. Re-align paper to cover the sensor
groove.
Problem
When I am using continuous feed paper, the sprocket holes are torn,
causing alignment problems.
Solution
The most likely cause is that the paper lever is set to friction feed.
Move the lever to "Fan-fold" (to the front of the printer)
