| Home > Problem Solver # 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 A4 size single-sheet paper or 10-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.
| When using continuous paper, 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.
| While holding down the Pause button, turn on the printer.
The printer enters the bidirectional adjustment mode. When using continuous paper, the printer prints the instruction sheet and the first set of alignment patterns.
| When using single-sheet paper, load paper in the printer. The printer 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. The Power, Pause and Paper Out lights show the pattern number which is selected at that time.
| Press the Pause 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 to exit the bidirectional adjustment mode.
