CUT Motor
Measurement
The cutter motor is designed to stop when the
amount of heat generation (motor temperature)
during motor operation reaches a predetermined
limit. The amount of heat generation is estimated
based on the electrical characteristics of the
motor, which vary by motor and power supply of
the printer. Therefore, to get the motor control to
work properly, the electrical characteristics
values of the motor need to be measured and
stored in the memory on the MAIN BOARD.
If this adjustment is not made, the estimation of
the motor temperature cannot be made properly
and may cause the following symptoms.
†
Even though there is no problem with the
motor temperature, the printer pauses during
printing because it judges that the motor is in
high-temperature state.
†
Despite the motor is in a high-temperature
state, a lower motor temperature is estimated
and the printer does not stop. This may cause
the printer to malfunction.

Paper thickness sensor
adjustment
Adjust the installation position of the sensor so
that the Paper thickness sensor detects the paper
thickness correctly. Adjust the paper thickness
sensor using the jig for paper thickness
adjustment.
If this adjustment is not made, the thickness of the
paper cannot be detected correctly. As the result,
the PG is not set correctly against the paper
thickness which is actually inserted.
†
When the PG becomes wider: Low print
quality such as unstable ink droplet paths or
misaligned dots
†
When the PG becomes narrower: Head rubbing

Rear AD Adjustment
Adjust the detection sensitivity of the PE
SENSOR so that it can recognize the paper
inserted in the printer correctly. Let the sensor
detect the Standard Sheet (translucent media)
which is hard to recognize to check the result on
the Control Panel. (By using the media which is
hard to recognize, paper can be recognized
regardless of the environmental condition or the
media)
If the adjustment is not executed, paper
recognition failures may occur (e.g. paper empty
error occurs even with paper inserted, some media
are not recognized).
