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

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.

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.
