E-36 Section 4
Problem: I’ve installed a brand new ribbon and the
printing is smeared and streaked.
Solution: The plastic ribbon shield is either loose or
missing. The shield must be left on the ribbon when you
are installing the cartridge. To remedy this situation,
(caution—printhead may be HOT!) move the printhead
to the center of the platen and lift off the ribbon car-
tridge. If the ribbon shield is loose, secure it in place
properly. If it’s missing, locate it and reinstall it.
Problem: I see printing on the right side of the page
which is lighter or darker than the rest of the print.
Solution: Although the printer automatically sets the
head gap, it may sometimes need minor adjustment. To
do this:
1. Hold SHIFT button and press SEL button to enter
Menu mode.
2. Press GROUP button until Setup group prints.
3. Press ITEM button until Printhead Gap appears.
4. Press SET button to change setting. The default setting
is 0. If the printing is sometimes lighter, change the
setting to -1; if it’s sometimes darker, change it to +1.
5. Hold SHIFT button and press SEL button to save
setting and exit Menu mode.
Problem: The Alarm light is on and the Character Pitch
15 light is flashing.
Solution: This indicates a paper loading error. To stop the
flashing light, press the SEL button. Before trying to load
paper again, check to be sure that the paper lever is in
the correct position (BOT, TOP, REAR) for the path
you’re using.
If the paper lever is in the correct position and you’re
using rear feed, lift up the paper separator and check to
be sure that the paper is properly on the tractors and has
not jammed up somehow.
If the paper lever is in the correct position and you’re
using the optional bottom-feed push tractor, check the
bottom tractor unit to be sure that the paper is properly
on the tractors and has not jammed up before entering
the printer.
Once the paper is correctly loaded, press and release the
SEL button, then hold the SHIFT button and press the
RESET (Character Pitch) button.
