Detection Timing
• The Motor Lock signal remains HIGH for a given period
of consecutive time while the LV Cooling Fan Motor is
being rotated.
• The Fusing Motor does not rotate evenly even after the
lapse of a given period of time while it is being started.
• The Motor Lock signal remains HIGH for a given period
of consecutive time while the Fusing Motor is being
rotated.
• The Retraction Position Sensor/2nd Image Transfer is
not activated (retracted position) within a given period
of time after the retraction sequence of the 2nd Transfer
Roller has been started.
• The Retraction Position Sensor/2nd Image Transfer is
not deactivated (pressed position) within a given period
of time after the pressure sequence of the 2nd Transfer
Roller has been started.
• The Retraction Position Sensor/1st Image Transfer is
not activated (retracted position) within a given period
of time after the Intermediate Transport Motor has
started rotating.
• The Retraction Position Sensor/1st Image Transfer is
not deactivated (pressed position) within a given period
of time after the Intermediate Transport Motor has
started rotating.
• The Polygon Motor does not rotate evenly even after
the lapse of a given period of time after it has been
started.
• The Motor Lock signal remains HIGH for a given period
of consecutive time while the Polygon Motor is being
rotated.
• The SOS signal is not detected within a given period of
time after the output of the laser has been started.
• The Heating Roller Thermistor does not detect the
specified temperature and the warm-up cycle is not
completed even after the lapse of a given period of time
after the cycle has been started.
• The Fusing Pressure Roller Thermistor does not detect
the specified temperature and the warm-up cycle is not
completed even after the lapse of a given period of time
after the cycle has been started.
• The temperature detected by the Heating Roller Ther-
mistor remains lower than the specified value for a
given period of time or longer.
• The temperature detected by the Fusing Pressure
Roller Thermistor remains lower than the specified
value for a given period of time or longer.
• The temperature detected by the Heating Roller Ther-
mistor remains higher than the specified value for a
given period of time or longer.
