< Operating Procedure >
Adjustment of vertical print lines
(1) Press the 6 and 5 keys in this order in the initial stage of the maintenance mode.
The "MAINTENANCE 65" appears on the LCD.
(2) Press the 1 key. The machine displays the "PRINTING" on the LCD and prints the vertical
alignment check pattern (see page 5-45 ).
Upon completion of printing, the "A NO. (1-9)" appears on the LCD.
(3) Check the A row, find which number block shows the most indistinct vertical lines, and
then enter that block number.
The "B NO. (1-9)" appears on the LCD.
(4) Check the B row, find which number block shows the most indistinct vertical lines, and
then enter that block number.
The "C NO. (1-9)" appears on the LCD.
(5) Check the C row, find which number block shows the most indistinct vertical lines, and
then enter that block number.
The "D NO. (1-4)" appears on the LCD.
(6) Check the D row, find which number block shows the most indistinct vertical lines, and
then enter that block number.
The machine saves the adjustment values and automatically returns to the initial stage of
the maintenance mode.
Note: If the 1 or 9 key is pressed during the above procedure, the machine shows "PRINTING"
on the LCD and prints the vertical alignment check pattern again. Go back to step (3) and make
adjustments again.
