Operating Procedure
Before starting the procedure below, be sure to set letter-size or A4-size paper in the paper tray

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 the 1 or 9 key is pressed in any of steps (2) to (4) above, the machine shows
"PRINTING" on the LCD and prints the vertical alignment check pattern again. Go back to step
