5.1.4.20 Alignment of Vertical Print Lines in Monochrome (Function code 65)
Function
This procedure aligns vertical lines printed in the forward and backward directions of the head/
carriage unit.
If the head/carriage unit, main PCB, engine unit, or carriage motor is replaced, you need to
make the adjustment given in this section.
Note: If the head/carriage unit or the engine unit is replaced, you need to make other
adjustments in addition, referring to Chapter 4, Section 4.1 [ 4 ].
Operating Procedure
Before starting the procedure below, be sure to set letter-size or A4-size paper in the paper tray
for printing check patterns.
(1) Press the 6 and 5 keys in this order in the initial stage of the maintenance mode. Then press
the 1 key in succession.
The machine displays the "PRINTING" on the LCD and prints the vertical alignment check
pattern of A to D rows (see the next page for a sample printout). Each of A to D rows
consists of #1 through #9 blocks.
The "A No. (1-9)" appears on the LCD.
(2) Check the A row, find which number block shows most indistinct vertical lines, and then
enter that block number.
The "B No. (1-9)" appears on the LCD.
(3) Check the B row, find which number block shows most indistinct vertical lines, and then
enter that block number.
The "C No. (1-9)" appears on the LCD.
(4) In the same way, enter the block number of most indistinct vertical lines for the C and D
rows.
The machine automatically returns to the initial stage of the maintenance mode.
Note: If #1 or #9 block is fully aligned so that you press the 1 or 9 key in the above procedure,
the machine shows "PRINTING" on the LCD and prints the vertical alignment check pattern
again. Go back to step (2) and make adjustments again.
