PF Motor Measurement
& Automatic
Adjustment
The PF 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.

Cut Position Check &
Adjustment
Adjust the auto cut with the auto cutter to cut
paper at the proper position. Feed the roll paper
and execute printing and cutting of the
adjustment pattern using the Service Program.
Measuring the gap between the bottom edge of
the printed paper and the pattern and inputting the
measurement result adjusts the cut position.
The cut position may be misaligned.
