Troubleshooting
1. When using continuous paper, make sure paper is loaded,
and the paper release lever is set to the correct position. Then
turn off the printer.
c
Caution:
Whenever you turn off the printer, wait at least five seconds
before turning it back on; otherwise you may damage the
printer.
2. To run the test using the Draft font, turn on the printer while
holding down the LF/FF button. To run the test using the
printer’s letter-quality fonts, turn on the printer while holding
down the
Load/Eject
button. Either self test can help you
determine the source of your printing problem; however, the
draft self test prints faster than the letter-quality test.
3. When using single-sheet paper, load paper in the printer.
After a few seconds, the printer loads the paper automatically
and begins printing the self test. A series of characters is
printed.
Note:
To temporarily stop the self test, press the Pause button. To resume
the test, press the Pause button again.
4. To end the self test, press the Pause button to stop printing.
If paper remains in the printer, press the Load/Eject button
to eject the printed page. Then turn off the printer.
c
Caution:
Do not turn off the printer while it is printing the self test. Always
press the
Pause button to stop printing and the Load/Eject
button to eject the printed page before you turn off the printer.
