3. Repair Details
3.1 Precautions
3.1.1 Precautions regarding ink stains
Be careful not to touch the ink path and stain the printer, work bench, hand, or clothes with ink during repair.
3.1.2 Precautions when releasing the carriage lock
The carriage locks at the capping position when the power is turned off normally, with the cartridge installed
in the carriage.
If the printer does not operate normally, manually release the carriage lock as necessary.
Turn the gear in the figure in the direction of the arrow to release the carriage lock.
Figure 1-1 Releasing Carriage Lock
3.1.3 Precautions when removing/installing tap screws
Tap screws are used to secure the printer unit and the base. When a tap screw is removed, mold scrap may
adhere to the screw threads, which can damage the mold-side threads when the tap-screw is re-fastened.
Therefore, remove the mold scraps adhered to the screw or use a new screw when re-installing.
3.1.4 Code strip handling precautions
1) Do not apply grease to the code strip.
If grease contacts the code strip, the code strip slits may become unreadable, causing errors.
If grease contacts the code strip, wipe off thoroughly with alcohol. 2) Do not bend or scratch the code strip.
Replace the code strip if it is scratched, or bent until it is white. 3) Extend the leaf spring when attaching or removing the code strip.
The code strip is held taut and secured by the leaf spring.
Note that if the spring is stretched too far in the direction of the arrow, it will not properly re-secure the
code strip.
Be careful not to pull too hard on the code strip when installing or removing it.

3.1.6 Logic board removal precautions
The Logic Board can be damaged due to short circuiting during removal.
When removing the Logic Board, unplug the power cord and allow the unit to sit for approximately 1 minute
to discharge the capacitor.

3.2 Adjustments
3.2.1 Waste ink counter setting
(1) When replacing the logic board, replace the waste ink absorber, depending on the value of the waste ink
counter.

3.4 Verification
(1) Print the nozzle check pattern when replacing the print head, sheet feeder unit, purge unit, or carriage unit.
(2) Check the connection with PC and print the nozzle check pattern when replacing the PCB.
4. Printer Transportation Method
This section describes the procedures for transporting the printer (for example, when returning after repair).
(1) Keep the print head in the carriage.
(2) Turn off the power and ensure that it is properly capped at home position.
If the print head is left alone by itself, the ink may solidify.
Therefore, keep the print head (with ink tank) in the carriage even when transporting.
Also, secure the carriage at home position to prevent it from moving and applying stress to the encoder film
during transportation.
If the print head must be transported by itself, perform the following:
1. Install ink tanks for each color. (to prevent nozzles from drying)
2. Install the orange protective cap on the print head.
(to prevent damage to the print head due to shock etc.)

2. Cleaning Mode and Suction Amount
Print head cleaning is performed effectively and efficiently depending on conditions in order to prevent print
errors caused by bubble, dust, or ink clogging.
Cleaning is performed before starting to print except at the following timing:
Dot count suction: Performed after paper ejection
Manual cleaning/refreshing: Performed during operation
Unit delivery: Performed when access cover is closed
