Follow the steps below to perform bidirectional adjustment.
Note:
❑ To print the instruction sheet and alignment patterns, you need
four sheets of A4 or letter size single-sheet paper or 11-inch or
longer continuous paper. (See Chapter 3, "Paper Handling," for
instructions on loading single-sheet or continuous paper.)
❑ 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.
1. Make sure paper is loaded, then turn off the printer. While
holding down the Pause button, press the Operate button
to turn on the printer. The printer enters the bidirectional
adjustment mode and then prints the instruction sheet and
the first set of alignment patterns.
2. As described on the instruction sheet, compare the alignment
patterns and select the pattern with the best alignment. To
specify the pattern number you want, press the LF/FF
button (to decrease to the number) or the Load/Eject
button (to increase to the number) until the Font lights
correspond to the correct number as indicated at the
bottom of the instruction sheet.
3. Press the Font button to save your selection and print the
next set of alignment patterns. Then repeat step 2 to select
the best alignment pattern.
4. Press the Font button again to save your selection and print
the final set of alignment patterns.
5. Select the best pattern in the final set of alignment patterns
as described in step 2 and then press the Font button to
save your selection.
6. Press the Operate button to turn off the printer and exit the
bidirectional adjustment mode.
