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.

acceleration and
deceleration correction
†
Auto Bi-d adjustment: Reduces misalignment
of ink droplets fired to paper during
bidirectional printing.
†
Acceleration and deceleration correction: To
improve print quality for bidirectional
printing, corrects the movement speed of the
CR UNIT.
†
Auto Bi-d adjustment: If this adjustment is not
made, print quality problems such as
misaligned lines, grainy image, banding may
occur.

PW + T&B&S check
and adjustment
†
PW: Checks that the PW sensor detects the
edges of paper correctly. Feed A4 matte paper
from the paper cassette and perform the
detection operation using the Service
Program.
†
T&B&S: Adjusts the print start position of the
top, bottom, right and left edges of paper.
Feed A4 matte paper from the paper cassette
and print the adjustment patterns using the
Service Program. Measure the adjustment
patterns then input the measurement result.
The print start position is automatically
adjusted.
If this adjustment is not made, the width or length
of paper cannot be detected correctly. As the
result, misaligned print position or insufficient
blank space may occur, or printed images may be
broken.
