Item
The Fan Lock signal remains HIGH for a prede-
•
termined continuous period of time while the
Motor remains stationary.
• The Motor Lock signal remains LOW for a predeter-
mined continuous period of time while the Motor
remains stationary.
• The 2nd Image Transfer Pressure Position Sensor is
not activated (retracted position) within 2 sec. after the
2nd Image Transfer Pressure/Retraction Motor has
started turning during a sequence of the 2nd Image
Transfer Roller's retracting motion.
• The 2nd Image Transfer Pressure Position Sensor is
not deactivated (pressed position) within 2 sec. after
the 2nd Image Transfer Pressure/Retraction Motor has
started turning during a sequence of the 2nd Image
Transfer Roller's pressing motion.
• The 1st Image Transfer Retraction Position Sensor is
not activated (retracted position) within 5 sec. after the
1st Image Transfer Pressure/Retraction Motor has
started turning during a sequence of the Transfer
Belt's retracting motion.
• The 1st Image Transfer Retraction Position Sensor is
not deactivated (pressed position) within 1 sec. after
the 1st Image Transfer Pressure/Retraction Motor has
started turning during a sequence of the Transfer
Belt's pressing motion.
• No change is observed in the encoder sensor pulse
even after the lapse of 0.5 sec. after the Fusing Pres-
sure/Retraction Motor has started turning for a
sequence of the Fusing Pressure Roller's retracting
motion.
• No change is observed in the encoder sensor pulse
even after the lapse of 0.5 sec. after the Fusing Pres-
sure/Retraction Motor has started turning for a
sequence of the Fusing Pressure Roller's pressing
motion.
• The Fusing Pressure Position Sensor is not activated
(pressed position) even when 30 encoder sensor
pulses are counted after the Fusing Pressure/Retrac-
tion Motor has started turning for a sequence of the
Fusing Pressure Roller's pressing motion.
