6-3-3. Impact Head Printing Dot Alignment Adjustment Mode
(1) With the front cover open, turn the power ON while keeping the RELEASE button
pressed.
(2) Close the front cover and place the paper in the printer. Then, the printer will print "Dot
Alignment Adjust Mode" and enter the impact head dot alignment adjustment mode. The
printer will continue printing a total of 22 patterns of dot alignment adjustments as shown
below. The patterns are staggered in 1/8-dot increments.
The printed line above each pattern shows a number between 1 and 23 and its setting value
(Lv.xx). The pattern preceded by a "*" mark indicates the present setting value.
(3) As shown below, the adjustment patterns that are printed consist of a three-dot bar each
at the top and bottom for the forward pass, and a three-dot bar in the middle for the back-
ward pass. Check the patterns visually and select a pattern with the three bars forming the
straightest line.
(4) To set up a pattern, press the RELEASE button as many times as the number (1 to 23) of
the desired pattern. In the process, a buzzer will make a short sound (0.1 second) with each
pressing of the RELEASE button.
