Common Problems

1. Nothing happens when the printer is powered ON.
Make sure the printer is plugged in.
Check the power cord connection to the printer and the outlet.
If a power strip is being used, make sure the strip is powered ON.
2. The ALARM lamp is lit.
The printer may be out of paper or the paper may have jammed. The SEL
lamp will not light. After loading paper, press the SEL switch.
If the ALARM lamp does not go out after paper is loaded, refer to Section 4.5
of this Service Handbook.
3. The printer does not print when the computer sends it data.
The printer may be deselected. Make sure that the SEL lamp is lit. If it is
not, press the SEL switch.
4. The paper keeps jamming.
Verify that the top of form is set so that the paper is held in place by the bail
bar. If the top edge of the page is below the bail, it will catch on the bail as it
advances. Do not use the FORM FEED switch to load paper into the printer.
If the paper does jam, power OFF the printer. Carefully back the paper out of
the paper path by using the platen knob. Remove any shreds of paper from
the paper path.
5. The printer suddenly changes to unidirectional printing. It then stops printing
completely. The MENU light is flashing.
This indicates a Printhead Overheat Condition. When the printer prints for a
long period of time, heat will build up in the printhead. When the printhead
temperature reaches approximately 115 degrees Celsius, the printer will print
unidirectionally. If the temperature continues to rise, printing will stop until
the printhead cools. Printing will resume after the printhead cools.
6. Static electricity causes the paper to stick.
In cold, dry weather, static charges can build up on continuous-form paper.
This can make the paper cling to the paper separator. If this problem occurs
during high-volume printing jobs, try moving the single sheet paper guides on
the separator together so that the paper rests on the guides rather than on the
separator itself.
