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, and LQ (letter quality). As described below, you select the best alignment pattern
from each sheet.
Note:
❏
To print the alignment patterns, you need three sheets of A3 size single sheet paper or 12 inch
(recommended) continuous paper.
❏
If you use single sheets, you need to load a new sheet of paper each time the printer ejects a printed
sheet from the sheet guide.
Follow the steps below to perform bidirectional adjustment.
1. Make sure paper is loaded and the printer is turned off.
!
Caution:
Whenever you turn off the printer, wait at least five seconds before turning it back on;
otherwise you may damage the printer.
2. While holding down the
button, turn on the printer. The printer enters bidirectional
adjustment mode.
