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:

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.

Turn on the printer while holing the F2 button.

Press the F1/Eject button while the F1/Eject, Offline, and F2 lights are flashing.

When the Ready light turns on, insert a sheet of A4 paper into the front slot. The printer prints the guide to adjust the bidirectional alignment and the first set of alignment patterns.

As described in the instructions, compare the alignment patterns and select the pattern with the best alignment. You can select the alignment pattern by pressing the F1/Eject button (for the next pattern) and the F2 button (for the previous pattern). The F1/Eject, Offline and F2 lights show the pattern which is selected at that time. Each time you press the F1/Eject or F2 button, the printer makes a short beep.

Set the pattern by pressing the Offline button. The printer prints the next set of alignment patterns.

After you select the best pattern in the final set of alignment patterns and set it by pressing the Offline button, turn off the printer. The setting does not change even if the printer is turned off.
