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
“BI-D Center” and input the approximation number that corresponding to the inclination of
misalignment you have confirmed previously. After changing the reference value for the Bi-D alignment
check printing, input “1” to select “(Production)” and back to the main menu and continue for the Bi-D
alignment adjustment from step 4.
Timing to write the specified value to EEPROM: Upon pressing ENTER key after input “Y”.
