Function
This function allows you to align vertical lines printed in the forward and backward direction of the
head/carriage unit.
If the head/carriage unit or main PCB is replaced with a new one, you need to make the adjustment
given in this section.

Operating Procedure
(1) Press the
6
and
5
keys in this order in the initial stage of the maintenance mode. Then press the
1
key.
The machine displays the "MAINTENANCE 65" on the LCD and prints two sheets of check
patterns as shown on the next page.
--------------------------------------------------------------------------------------------------------------------
----
On the 1st sheet, two sets of vertical alignment check patterns in monochrome are printed for
600 dpi and 1200 dpi, each of which consists of #1 through #8 blocks. If the vertical alignment
is ON, #5 block (each in the 600 and 1200 dpi printouts) shows vertically aligned lines.
On the 2nd sheet, the vertical alignment check pattern is printed for 750 dpi.
--------------------------------------------------------------------------------------------------------------------
----
The "600DPI NO. (1-8)" appears on the LCD.
(2) On the 1st sheet, check the printed vertical alignment check patterns for 600 dpi in monochrome
and find which number block shows full alignment.
If the block is other than #5, enter that block number by using the numerical keys.
The "1200DPI NO.(1-8)" appears on the LCD.
(3) For 1200 dpi, perform the same operation as in step (2).
The "750DPI NO.(1-8)" appears on the LCD.
(4) On the 2nd sheet, check the printed vertical alignment pattern for 750 dpi and perform the same
operation as in step (2).
The machine automatically returns to the initial stage of the maintenance mode.
NOTE:
If #1 or #8 block is fully aligned so that you press the
1
or
8
key (or you enter 1 or 8) in the
above procedure, then go back to step (1) to confirm that #5 block becomes aligned.
