Aligning Vertical Lines in Your Printout

If you notice that the vertical lines in your printout are not
properly aligned, you can use the printer's bidirectional
adjustment mode to correct this problem.
During bidirectional adjustment, the printer prints three sheets of
alignment patterns, labeled Draft, Bit image (ESC * 26H), and LQ
(letter quality). As described below, you select the best alignment
pattern from each sheet.
Note:
Prepare an A4 size sheet of paper before entering the bidirectional
adjustment mode.
Follow these steps to perform the bidirectional adjustment:
1. Turn off the printer.
c
2. Turn on the printer while holing the F2 button.
3. Press the F1/Eject button while the F1/Eject, Offline, and F2
lights are flashing.
Caution:
Whenever you turn off the printer, wait at least five seconds
before turning it back on; otherwise you may damage the
printer.
