4.2 Adjustments
This section describes the detail procedure of each adjustment.
4.2.1 Paper Gap Adjustment
The paper gap is a distance between nozzle surface of the printhead unit and a paper surface and is
adjusted to specified gap at the assembly. Therefore, if the carriage assembly is removed from the printer
mechanism for any reason, this adjustment should be made to fix the gap.
CAUTION
Do not scratch the surface of “PAPER GUIDE, FRONT;B” and “ROLLER, ASSEMBLY, PF”.
Be careful not to damage or make dirty the nozzle surface of the printhead unit.
[Paper gap - Right-hand side Adjustment]
1. Attach both “BUSH, PARALLEL ADJUST” (L/R) to the side frame and align the position mark on top
edge of it to a notch on the edge of the side frame.
2. Set “LEVER, PG” to front side (Position “0”).
3. Move the carriage assembly to the middle, and put the thickness gauge at the position specified in the
figure.
4. Move the carriage assembly over the thickness gauge.
WORK POINT
The thickness gauge must be placed on a flat surface of the ribs of “PAPER GUIDE, FRONT;B”.
During adjustment, always pull the timing belt to move the carriage assembly.
5. Shift the position of “BUSH, PARALLEL ADJUST, RIGHT” to backward (Gap: Narrower) until when the
thickness gauge starts sliding together with the carriage assembly when you move it to right and left for
about 20mm.
6. At the point of above step, shift the position of “BUSH, PARALLEL ADJUST, RIGHT” for one notch to
forward (Gap: Wider).
7. Then, confirm that the thickness gauge do not slide when you move the carriage assembly, with either
“LEVER, PG” is at position “0” or “+”.
[Paper gap - Left-hand side Adjustment]
8. Repeat the above step 2 to 7 with “BUSH, PARALLEL ADJUST, LEFT”.
[Gap Confirmation]
9. Repeat the step 3 to 4 again.
10. Confirm that the thickness gauge do not slide when you move the carriage assembly to right and left
for above 20mm.
11. Shift the position of “BUSH, PARALLEL ADJUST, RIGHT” for one notch to backward (Gap: Narrower)
and confirm that the thickness gauge is sliding by moving the carriage assembly. If not, return to step 1
and repeat adjustment again.
12. If the gap is correct, shift “BUSH, PARALLEL ADJUST, RIGHT” for one notch to forward (Gap: Wider).
[Fixing “BUSH, PARALLEL ADJUST”]
13. Fix both bushes with 2 screws (1 each : No.1).
When the paper gap adj ustment complete, confirm that the overlap of printhead nose and “CLEANER,
HEAD”.
1. Move the carriage assembly next to “CLEANER, HEAD”.
2. Confirm that the overlap of printhead nose and top edge of “CLEANER, HEAD” is more than 0.5mm.

4.2.2 Adjustment using Adjustment Program
Since the characteristic of printer mechanism and its components are varying, every printer mechanism
are checked and it’s own characteristic information is stored in EEPROM of the main control board as a
compensation parameter for the mechanism control. Therefore, if the combination of printer mechanism
and the main control board is changed, the printer should be adjusted using the adjustment program in
order to maintain optimum performance of the printer.
4.2.2.1 Overview of Adjustment Program
This adjustment program(K00A10VE.BAS) is developed specifically for this printer and the basic operation
with this adjustment program is illustrated in figure below.

4.2.2.5 Head Angular Adjustment
The head angular means the angle at which the printhead unit installed on the carriage assembly against
the carriage movement direction and the printhead must be parallel with the carriage movement direction
so that the lines printed with each nozzle are evenly positioned. Therefore, this adjustment should be
made when the following service is made:
Replacing or removing the printhead unit
The head angular actually set by the adjust lever installed on the carriage assembly and the program print
the check pattern to see the level of head angular.
*Refer to next page for [SCREEN-1] to [SCREEN-2].

4.2.2.6 Bi-D Alignment Adjustment
This adjustment defines the carriage drive control parameters to compensate the variation in mechanism
components characteristic so that the print position become even in bi-directional printing. This
adjustment is required when one of the following service is made:
Replacing the printer mechanism
Replacing the main board (C209 MAIN)
Replacing the CR Motor assembly
Replacing the carriage assembly
The values defined with this adjustment are stored in EEPROM on the main board.
*Refer to next page for [SCREEN-1] to [SCREEN-3].
1. If the printer mechanism is replaced, the ink charge operation and the VH Setting operation should
be performed prior to this adjustment. (Refer to section 4.2.2.3 and 4.2.2.4)
2. Go to the main menu [SCREEN-1].
3. Input “4” to select “Bi-d Adjust” and press ENTER key.
4. The program prints the check pattern (one with the compensation value=“0” and another two patterns
each printed with the value “-2” and “+2”). Select the number of the pattern with which the printed lines
are most properly aligned, and input the number and press ENTER key at the menu [SCREEN-2].
Then, the program print the sample pattern with the compensation value you have selected.
5. If all patterns printed by the program are completely mis-aligned, confirm the inclination of
misalignment with the pattern printed with the value “0” by checking the relative position of the EVEN
line to the ODD line:
If EVEN line is shifted to RIGHT = Requires (−) value
If EVEN line is shifted to LEFT = Requires (+) value
Then, once input “Y” and press ENTER key to return to the main menu, and input “E” to select “Go to
SETTING MENU” and press ENTER key. At the setting menu screen [SCREEN-3], input “6” to select
