Problem
Continuous-form paper sticks to the sheet guide.
Solution
In cold dry weather, static charges can build up and make the paper
cling to the sheet guide. Try moving the paper guides together so that
the paper rests on the guides rather than on the separator.
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.
