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.
