Item
• The error was found when reading out the counter
value.
the fusing roller retraction sensor does not change
even after the specified period of time has passed
after the fusing retraction motor started rotating.
• With the fusing roller being pressed, the pulse of the
roller retraction sensor does not change even after
the specified period of time has passed after the fus-
ing retraction motor started rotating.
• During a pressure operation of the fusing roller, the
fusing roller is not at the pressed position even after
the roller retraction sensor counts the specified num-
ber of pulses after the fusing retraction motor starts
rotating.
• The motor lock signal remains HIGH for a predeter-
mined 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 fan motor lock signal remains HIGH for a prede-
termined continuous period of time while the motor
remains stationary.
• The fan motor lock signal remains HIGH for a prede-
termined continuous period of time while the motor
remains stationary.
• The temperature detected by the heating roller ther-
mistor/C does not reach a predetermined level after
the lapse of a predetermined period of time after the
heating roller fusing heater lamp lights up.
• The difference between the maximum and minimum
temperatures detected by the heating roller ther-
mistor/C within a predetermined period of time after
the start of a warm-up cycle is below or above a pre-
determined value.
• The temperature detected after a pressure level cor-
rection remains under a predetermined level even
after the lapse of a predetermined period of time
after the start of the temperature detection.
• During a warm-up, a zero cross signal cannot be
detected after the lapse of a predetermined period of
time after the fusing heater is turned ON or OFF.
• After warm-up operation starts, the fusing pressure
roller thermistor does not detect a temperature as
high as a predetermined one though a predeter-
mined period of time has elapsed.
• The temperature of the pressure roller remains lower
than a predetermined level even after the lapse of a
predetermined period of time after a temperature
correction.
