To perform micro adjustment of the loading position, first load
your paper, and then press the ON LINE button to set the printer on
line. The MULTI-PART indicator light starts to flash. While this light
is flashing, you can use the FORM FEED and LINE FEED buttons for
micro adjustments.
Now press the FORM FEED button to feed the paper forward or
the LINE FEED button to feed the paper backward.
Each time you press the button, the paper moves 1/180 of an
inch. If you hold the button down, the paper moves continuously in
1/180 of an inch increments.
When the paper reaches the factory set loading position, the
printer beeps and micro-adjustment feeding pauses for a moment
before continuing. You can use this factory setting as a reference
point when adjusting the printer's loading position.
Micro adjustment can be used to adjust the loading position
immediately after loading paper only. Using micro
adjustment on continuous paper establishes a new loading
position that remains valid even after the printer is turned
off, reset, or initialized. When using micro adjustment on
single sheet paper, the new loading position does not remain
valid after the printer is turned off or reset. When the paper
reaches either the minimum or maximum top margin, the
printer beeps and the paper stops moving.
