Detection Timing
See the relevant option service manual.
• The Main Erase Lamp Malfunction signal remains
LOW for a continuous 1-sec. period while the Main
Erase Lamp remains OFF.
• The Main Erase Lamp Malfunction signal remains
HIGH for a continuous 1-sec. period while the Main
Erase Lamp remains ON.
The output voltage from the AIDC Sensor Board does
not fall within the range of 0.9V to 1.1V even after the
contamination correction and variation adjustment
have been made.
• The output voltage from the ATDC Sensor remains
0.2V or less, or 4.5V or more, for a continuous 3-
sec. period after the Developing Unit Drive Motor
has been energized.
• The output voltage from the ATDC Sensor does not
fall within the range of 2.45V to 2.55V during an F8
operation.
A T/C of 2.5% or less (ATDC Sensor output being
2.86V or more) is detected.
• No Lock signals are detected for the period of 5 to
20 sec. after the motor has started turning after the
Power Switch was turned ON.
• No Lock signals are detected for the period of 5 to
20 sec. after the motor has started turning at full
speed after the Start key was pressed.
• The Lock signal remains HIGH for a continuous
period of 3 sec. or more while the motor is running
at steady speed.
No answer is received within 1.5 sec. to a report trans-
mitted by the engine.
A LOW VD signal is not detected even after the lapse
of 60 sec. after an IDREQ signal has been output.
