TROUBLESHOOTING

If you have tried the corrective actions listed in Tables 5-1,5-Z, and 5-3, and your printer
still will not print correctly, try the following troubleshooting techniques.

Self-Test

with the printer itself.
Load paper into the printer and turn off the power.
For best results, use continuous papers to run the entire self-test.

To stop the self-test, simply turn off the printer power.
Your self-test printout (see pase 6) provides the first print position, print head test
pattern, and the printer internal fonts. The print head test shows any pins that may be
broken. The solid horizontal lines printed at the both sides of the printer model name
("Pinwriter P2000" for P2000, "Pinwriter P2x" for P2X) should have no missing or
discontinuous bars.
