4.2.2.3 Ink Charge Operation
If either of the following service is made, internal ink paths of the printhead unit is completely empty. Therefore, a brand-new ink cartridge must be installed and all ink paths must be charged with fresh ink by performing the following operation to ensure proper printing operation.

Replacing the printer mechanism Replacing the printhead unit

CAUTION
Since this operation consumes large amount of ink, do not perform it unnecessarily: *Black: Approx. 8.8% of the ink charged in the cartridge *Color: Approx. 16.2% of the ink charged in the cartridge (CMYcm total) The ink charge operation takes long time to complete. Do not turn off the printer until it stops completely.(The POWER indicator blinks during the operation.)

1. Start "Preparation for Adjustment" and complete 1 to 4 procedures. (Refer to section 4.2.2.2) 2. At the main menu [SCREEN-3], input "2" to select "Ink Charge" and press ENTER key. Then, the printer starts the ink charge operation.

4.2.2.4 VH Setting
The piezo-electric element used in each printhead unit has unique electrical characteristic and the electrical characteristic of each printhead is measured at the production and each printhead unit is given with the ID code. Therefore, this ID code is need to be stored in EEPROM on the main board when the following service is made and the printer read this information to compensate the difference of characteristic for printing control and an amount of injected ink is maintained at the specified level.

Replacing the printhead unit Replacing the printer mechanism (the after-service unit comes with the printhead unit installed)

*Refer to the next page for [SCREEN -1] to [SCREEN-3]. 1. When replacing the part mentioned above, take a note of the ID code indicated on the unit as below.

Re-assemble the printer. Start "Preparation for Adjustment" and complete 1 to 4 procedures.(Refer to section 4.2.2.2) At the main menu [SCREEN-1], Input "1" to select "VH Setting" and press ENTER key. At the next menu screen[SCREEN-2], input "0" as "M/C No." and press ENTER key. Then next menu [SCREEN-3] appears on the screen, and input the ID code which you noted at the beginning of this procedure.

VH ID Code format:

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]. 1. Before performing this adjustment, be sure to perform "VH Setting" (Refer to section 4.2.2.4) 2. At the main menu [SCREEN-1], input "3" to select "Angular Adjust Printing" and press ENTER key. 3. Check to see if the lines printed in MAGENTA color is positioned in the middle of two BLACK lines with the check pattern printed by the program. If the position of MAGENTA lines are incorrect, input "K" to select "Angular Adjust Setting" at the main menu and the carriage assembly moves to the middle of the printer. Then, loosen a screw (No.3) fixing "FASTNER, HEAD" a little bit and shift the position of angular adjust level located at the right bottom of the carriage assembly to either forward (move MAGENTA line to down) or backward (move MAGENTA line to up). 4. After adjusting the position of angular adjust lever, input "Y" and press ENTER key and the carriage assembly returns to the home position. 5. Input "3" to print the check pattern again. If the level is still not correct, repeat the step 3 and 4. 6. If the level is correct, input "K" again and tighten a screw to fix "FASTNER, HEAD". Then, at the menu [SCREEN-2], input "Y" and press ENTER key to complete the adjustment.

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 = If EVEN line is shifted to LEFT =

Requires (-) value 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.
