CR Belt Tension Check
Apply a specified tension to the CR timing belt.
Measure the tension of the belt using the sonic
tensimeter to check if it is within standards. If
not, adjust the tension.
When the belt tension is out of standards, the
following symptoms may occur.
Belt tension is high:
The life of the belt will be shortened. High
load applied to the carriage causes frequent
wait control over the carriage movements to
prevent overheating. If the tension is too high,
the shaft of the motor leans and the brush in
the motor becomes worn, and will result in CR
overload error (113A).
Belt tension is low:
The belt teeth slip and the carriage swings.
The correction by the active damper does not
work and the bands (vertical bands) occur near
the side edges of paper.

APG function check
Rotate the APG motor to change the PG, and see
if the PG is correctly set to its home position
(TYP).
When the PG is not switched properly responding
to the print setting, low image quality or CL
operation abnormality may occur.

Ink Mark Sensor check &
Auto Adjustment
Check if the Ink Mark Sensor has any trouble/
connection failure.
Execute IMS Position Auto Correction
(pattern detecting position correction).
Correct the detecting position of the print
pattern in the sub scan direction and the main
scan direction.
Run the nozzle check to check if the Ink Mark
Sensor detects the nozzle clogging properly.
If the IMS does not work properly, automatic
adjustments such as Auto Bi-D Adjustment
cannot be executed normally.

CR Scale Check
Check the CR Scale for any abnormality such as
damage or dirt and check if the scale can be
properly read by the encoder.
When the CR Scale is not read properly, the
carriage will not operate normally.

CR Active Damper
Adjustment (Automatic)
Calibrate the active damper.
* Active damper is a function to reduce the
carriage vibration which causes vertical bands on
prints by outputting waveforms which have
phases opposite to the motor vibration.
Because the motor vibration/carriage vibration
cannot be reduced, vertical bands may appear on
prints.
