Cause
• The SSR1 has a short circuit.
• The CPU PCB is faulty.
• DC driver PCB is faulty.
• The cleaning belt inside the fixing
assembly has been taken up for a
specific length.
• The fixing cleaning belt length
sensor (PS11/PS67) is faulty.
• The DC driver PCB is faulty.
• The CPU PCB is faulty.
• The drawer connector of the fixing
unit is faulty.
• The DC driver PCB is faulty.
• The CPU PCB is faulty.
• The fixing oil pump driver PCB is
faulty.
• The DC driver PCB is faulty.
• The CPU PCB is faulty.
• The main motor (M4) is faulty.
• The main motor drive system is
subjected to an overload.
• The main motor driver PCB is
faulty.
• The DC driver PCB is faulty.
• The CPU PCB is faulty.
• The drum motor (M2) is faulty.
• The drum motor drive system is
subjected to an overload.
• The DC driver PCB is faulty.
• The CPU PCB is faulty.
• The waste toner feedscrew lock
detecting switch (SW7) is faulty.
• The waste toner feedscrew is
faulty.
• The DC driver PCB is faulty.
• The CPU PCB is faulty.
Timing of detection
xx indicates a heater.
xx=01: upper heater
xx=02: lower heater
xx03 The gate array of the DC
driver PCB has determined
that SSR1 (for the fixing
heater) is on for about 1.6 sec
or more even after the DC-
CPU turned it off.
0100 As many as 2,000 copies have
been made after the fixing
upper cleaning belt length
sensor detected the sensor
lever and indicated a warning
on the control panel.
0200 As many as 2,000 copies have
been made after the fixing
lower cleaning belt length
sensor detected the sensor
lever and indicated a warning
on the control panel.
0000 During copying operation, the
connecton signal (CNCT*) for
the fixing assembly drawer
connector goes '1'.
0000 The fixing oil pump driver
PCB does not generate the
drive signal even when the
fixing oil pump drive signal
has been turned on.
0001 The fixing oil pump driver PCB
generate the drive signal even
when the fixing oil pump drive
signal has been turned off.
The main motor ready signal
(MNMRDY) is '0' for 1 sec or more
while the main motor is rotating.
0001 Not used.
0002 The drum motor ready signal
(DRMRDY) is '0' for 1 sec (4
sec during deceleration) while
the drum motor is rotating.
The waste toner feedscrew cannot
rotate, and the waste toner feedscrew
lock detecting switch has been
pressed.
