weather heating is used because low humidity increases static
electricity.
Adjustments
Bi-directional Alignment Adjustment
Perform this adjustment with the black print cartridge installed.
1. Turn off the printer.
2. Hold down the Install Print Cartridge button and the Line Feed
Button, then turn on the printer. Release the buttons when all the
lights go out.
3. A page loads and the bi-directional alignment pattern prints. The
pattern consists of three lines of vertical bars. The bars are
aligned when the adjustment is correct. The following sample
requires the center vertical bars to be moved to the right.
4. The center bars can be coarse aligned or fine aligned. Coarse
alignment moves the center bar 1/300” (.085mm). Fine align-
ment moves the center bar 1/1200” (.021mm). To perform the
coarse alignment, open the operator panel cover and use the top
two buttons to move the center bar. Press the left button to move
the bar to the left. Press the right button to move the bar to the
right. Each time you press the button the three lines will print.
5. To fine align the bars, close the operator panel cover and use the
two bottom buttons. Press the left button to move the center bar
to the left. Press the right button to move the bar to the right.
Each time you press a button the three lines will print.
6. When the alignment is correct, press the Draft button to switch to
the draft mode. Follow the same procedure as above to align the
bars in the draft mode.
7. When you complete the adjustment and turn off the printer the
settings will be saved in NVRAM.
