Description
• The BD signal does not arrive within 1
sec after the output of the laser drive
signal.
• The BD signal does not arrive for 1 sec
or more while the laser is on.
• The laser power data cannot be written
to the laser driver PCB 1 when starting
copying or printing operation.
• The constant speed rotation signal (LM-
RDY) does not arrive for 15 sec or more
after the output of the laser scanner
motor (M4) drive signal.
• The lock signal (FM14LCK) is detected
for 5 sec or more while the laser scanner
fan (FM14) is being driven.
• The lock signal (FM5LCK) is detected
for 5 sec or more while the laser driver
cooling fan (FM5) is being driven.
• The scanner home position is not
detected within a specific period of time
when the power switch or the Copy Start
key is pressed.
• No image signal is detected while the
scanner is moving forward in fixed
reading mode or when the home position
is being detected.
• No image signal arrives from the ADF
while in stream reading mode.
• The temperature around the fluorescent
lamp does not exceed 10°C 2 sec after
the fluorescent lamp heater has turned on
at power-on.
• The temperature around the fluorescent
lamp is 0°C or less at power-on.
• The temperature around the fluorescent
amp is 170°C or more when the
fluorescent lamp is off.
