temperature) during motor operation reaches a
predetermined limit. The amount of heat

Overview Symptoms that the Adjustment is Needed
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.
When cartridges or tanks are not recognized
When the cleaning cartridges are not recognized
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 PF motor causes frequent
wait controls during paper feeding 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 PF
motor overload error (112A).

Belt tension is low:
The belt teeth slip and paper cannot be fed
properly.
