Troubleshooting

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, Draft, Bit Image, and LQ (letter quality). Select the best alignment pattern from each sheet to align vertical lines.

Follow the steps below to perform bidirectional adjustment.

Note:
  • To print the instruction sheet and alignment patterns, you need four sheets of A3 size single-sheet paper or 15-inch (recommended) continuous paper. (See Loading Continuous Paper or Loading Single Sheets for paper-loading instructions.)
  • If you use single-sheet paper, be sure to load a new sheet of paper each time the printer ejects a printed sheet. Otherwise, you cannot proceed to the next step.

Make sure paper is loaded, then 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.

While holding down the Pause button, turn on the printer. The printer enters the bidirectional adjustment mode and then prints the instruction sheet and the first set of alignment patterns.

As described in the instructions, compare the alignment patterns and select the number of the pattern with the best alignment using the LF/FF and Load/Eject buttons. Font lights show the pattern number which is selected at that time.

Enter the number of the pattern of your choice by pressing the Font button. The printer prints the next set of alignment patterns.

Repeat steps 3 and 4 to select and enter the number of the pattern with the best alignment for each of the remaining sets.

Turn off the printer and exit the bidirectional adjustment mode.
