PROBLEM
Ink smears on the paper
when I print narrow
columns.
I've installed a new
ribbon and the printing
is smeared and
streaked.
There are dots missing
in my printouts.
The ALARM light is
flashing.
The ALARM light is ON
and the Character Pitch
10 light is flashing.
The ALARM light is ON
and the Character Pitch
15 light is flashing.
The printer needs paper.
The ALARM is not ON
and I can't load paper.
Continuous form paper
sticks to the sheet
guide.
The Print Quality and
Character Pitch keys on
the front panel don't
work.
SOLUTION
This may be caused by excessive printhead travel from the
centering position. Enter the Menu and set the Centering Position
to MODE 1. See "Using Your Printer, Menu Mode."
For the wide-carriage printer, if MODE 1 doesn't work, try setting
the Centering Position to MODE 2.
The ribbon shield (1) is either loose or missing.
1
Remove the ribbon cartridge and check the ribbon shield.
> If it is loose, secure it.
> If it is missing, find it and install it.
The head gap may not be set correctly. Try moving the headgap
lever.
Try turning the printer OFF and then back ON again. If the light
still blinks, call for service.
This indicates that the paper lever is set at the wrong position for
the paper you are trying to use. Move it to the proper setting.
This indicates a paper jam. Press the SEL key and correct the
paper jam situation. See
1. Press and release the SEL key.
2. Press and hold the SHIFT key and press the RESET/
CHARACTER PITCH key.
The ALARM light illuminates and you can now load paper.
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.
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.
