You should use paper at least 210 mm (8 1/4 inches) wide to
run the self test; otherwise, the print head prints directly on
the platen.

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.

Caution:
Whenever you turn off the printer, wait at least five seconds
before turning it back on; otherwise you may damage the
printer.

LF/FF button.

After a few seconds, the printer loads the paper automatically
and begins printing the self test. A series of characters is
printed.

To temporarily stop the self test, press the Pause button. To resume
the test, press the Pause button again.

paper remains in the printer, press the LF/FF button to eject
the printed page. Then turn off the printer.
