POSSIBLE CAUSE/CORRECTIVE ACTION
Paper supply in lower enclosure not aligned
•
properly.
Paper snagging on box. Cut top of box off.
•
Paper not loaded properly. Reload paper and
•
check tractors for proper adjustment.
Excessive tension on paper.
•
Readjust paper tension lever, readjust print gap
•
wheel, check right side upper and lower tractors
for correct lateral paper tension.
Paper jams are most often caused by incorrect
•
paper tension (see above) or misaligned tractors
or paper.
1. Turn the print gap wheel to the LOAD position
and physically clear paper jam.
2. Reload paper, readjust right side tractors, paper
tension, and gap.
3. Press CLEAR key to print buffered data and to
clear the fault display.
Ribbon worn. Install a new ribbon.
•
Paper gap too large. Adjust print gap wheel to a
•
smaller gap.
Ribbon cartridge improperly installed. Check
•
installation by repeating installation procedure.
Print heads too close to paper. Adjust paper gap
•
setting for thicker paper.
Check for loose cable connection on print head
•
actuators.
Bad Actuator indicates that an actuator or the
•
driver circuit controlling that actuator has failed
the printer's test of the circuit. Try replacing the
actuator.
Driver Circuit is displayed when the printer's self
•
test determines that ALL of the actuators or wire
drivers are defective.
When either of these occur, call for service.
•
Continue to use printer if light or missing dots
can be tolerated temporarily.
