7.5.13 Alignment of Vertical Print Lines
Function
This function allows you to align vertical lines printed in the forward and backward direction of
the carriage.
NOTE: Before this alignment job, be sure to correct the positioning error of the print head. (Refer
to CHAPTER 6, Section 6.3 "ADJUSTMENT.")
Operating Procedure
(1) Press the 6 and 5 keys in this order in the initial stage of the maintenance mode.
The equipment prints out a set of vertical alignment check patterns which consist of No. 1 to
No. 9 lines for each of the 600 dpi, 1200 dpi, and 450 dpi.
If the vertical alignment is ON, No. 5 line (each in the 600 dpi, 1200 dpi, and 450 dpi
printouts) shows vertically aligned lines as given on the next page.
The LCD shows the "600DPI NO.(1-9)."
(2) Check the printed vertical alignment check patterns for the 600 dpi and find which number
line shows full alignment. If the line is other than No. 5, enter that line number by using the
numerical keys.
The LCD shows the "1200DPI NO.(1-9)."
(3) For the 1200 dpi, perform the same operation as in step (2).
The LCD shows the "450DPI NO.(1-9)."
(4) For the 450 dpi, perform the same operation as in step (2).
The equipment automatically returns to the initial stage of the maintenance mode.
NOTE: If No. 1 line or No. 9 line is fully aligned so that you press the 1 or 9 key in the above
procedure, then go back to step (1) to confirm that No. 5 line becomes aligned.
