CR Motor Measurement
& Automatic Adjustment
The CR 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.
Normal
mode
Auto Uni-d adjustment
Reduce misalignment of ink droplets fired to
paper during unidirectional printing.
If this adjustment is not made, print quality
problems such as misaligned lines, grainy image,
banding may occur.
Normal
mode
Auto Bi-D Adjustment
Reduce misalignment of ink droplets fired to
paper during bidirectional printing.
If this adjustment is not made, print quality
problems such as misaligned lines, grainy image,
banding may occur.
Normal
mode
PG adjustment
Adjust the platen gap of the CR Unit using the
thickness gauge.
When the PG is out of standards, the following
symptoms may occur.
Gap is too wide:
Unstable ink droplet paths or misaligned dots
occur, and it causes low printing quality such
as banding, printing misalignment, or grainy
image.
Gap is too narrow:
The head rubs paper.
