Detection Timing
The state of the Retraction Position Sensor/Cleaning Blade
is not changed from the blocked to unblocked state even
after the lapse of a predetermined period of time during
predrive.
The Retraction Position Sensor/Cleaning Blade is in the
blocked state even after the lapse of a predetermined
period of time during predrive.
The Retraction Position Sensor/Cleaning Blade is not
unblocked (blade in the retracted position) within a
predetermined period of time after the retraction sequence
of the Cleaning Blade has been started.
The Retraction Position Sensor/Cleaning Blade is not
blocked (blade in the pressed position) within a
predetermined period of time after the pressure sequence
of the Cleaning Blade has been started.
The Belt Positioning Sensor does not detect the Transfer
Belt position detection hole a second time even after the
lapse of a predetermined period of time after it has
detected one while the Transfer Belt is rotated.
The Rack Positioning Sensor is in the blocked state when
the Rack Motor remains de-energized.
The Rack Positioning Sensor is not blocked a second time
even after the lapse of a predetermined period of time after
it has been blocked once while the Rack Motor remains
energized.
The Rack Positioning Sensor is unable to detect the
deceleration control position after the lapse of a given
period of time after the Rack Motor has started while the
Rack Motor is turning.
The count value of the edge of ON signal of the Rack
Positioning Sensor during each developing positions are
not a predetermined value while the Rack Motor is turning.
The Thermistor does not detect a predetermined
temperature value even after the lapse of a predetermined
period of time after the current warm-up cycle has been
started and the current warm-up cycle is thus not
completed.
The temperature detected by the Thermistor remains lower
than a predetermined value for a predetermined period of
time.
The temperature detected by the Thermistor is a
predetermined value or higher for a predetermined period
of time.
The condition of a temperature rise of less than 1° C
extends continuously for a predetermined period of time
that begins when the warm-up cycle is started.
It is determined that the OHP Sensor is faulty through a
check made at the end of the predrive.
It is determined that the LED and photoreceiver are faulty
through a check made when a new Imaging Unit is
detected.
