3-3-5. Faulty cutter
Problems The cutter remains in the lower position.
The cutter will not come down.
Causes 1) The cutter fails to go up/come down smoothly. (The cutter moves jerkily.)
2) The cutter height is not correct.
3) There is a short in the cutter drive circuit.
Checking procedure 1) Remove the head cover and check whether or not the cutter can be
smoothly lifted/lowered by hand.
2) Remove the head cover and fully lower the cutter by hand to check whether
or not the cutter comes in contact with any other component.
3) Check whether or not the cutter goes up (abnormal state) when turning
the power off or detaching the connector from the slider PCB in the
solenoid with the cutter held lowered.
Remedies 1) Replace the cutter unit with a new one.
2) Adjust the height of the cutter assy.
3) Replace the main FPC, the main PCB, the slider PCB with a new one.
