CHAPTER 10 TROUBLESHOOTING
10-100
Code Cause
The density sensor is faulty.
The developing rotary assembly is
faulty.
The holding plate lifter (multifeeder) is
faulty.
The duplexing roller of the duplexing
unit drive mechanism is faulty. (The
duplexing unit is an accessory.)
The horizontal registration guide
mechanism of the duplexing unit is
faulty. (The duplexing unit is an
accessory.)
The temperature/humidity sensor is
faulty.
The laser of the scanner unit is faulty.
The laser scanner motor is faulty.
The EEPROM on the DC controller
PCB is faulty.
Description
During image stabilization correction
control, the LED intensity signal
(LEDCNT) is not generated or, if gen-
erated, is not received by the diode
1/2 normally.
• The developing rotation position
sensor (PS3) does not detect the
rotation position flag even when the
developing rotary motor has rotated
for a specific time.
• The developing rotary position sen-
sor (PS3) detects a faulty or wrong
rotation position flag width.
During multifeeder pick-up, the hold-
ing plate position sensor (PS1302)
does not detect the holding plate
even when the DC controller PCB
has generated the holding plate sole-
noid (SL4) ON signal.
The duplexing feeding roller 1 home
position sensor (PS23) does not
detect the home position of the
duplexing feeding roller 1 when paper
is being fed to the duplexing unit.
The duplexing driver PCB has detect-
ed that the horizontal registration
guide has moved in excess of the
maximum distance from when the
home position has been detected.
During image stabilization control, the
DC controller PCB cannot detect the
temperature sensor signal (TMPSNS)
or the humidity sensor signal (HUM-
SNS).
The DC controller PCB detects
BDERR for 2.5 sec or more after the
scanner motor has rotated at a spe-
cific speed.
• The scanner motor fails to reach a
specific revolution within 10 sec
after it has started to rotate.
• The BD PCB detects an error within
2.5 sec after the scanner motor has
rotated at a specific revolution.
The EEPROM (IC212) on the DC
controller PCB has an error.
