7. TROUBLESHOOTING IMAGE FAULTS/MALFUNCTIONS
0001 The triac is ON after the CPU on the
DC controller PCB has turned ON the
fixing heater triac drive signal.
0002 The triac is ON after the microproces-
sor on the DC controller PCB has
turned OFF the triac drive signal for the
drum heater.
The cleaning web solenoid has turned ON 270
times after the web length sensor detected the
lever.
0001 The fixing drawer connector connec-
tion signal CONNECT goes '0' when
the front cover is closed (i.e., the
drawer connector is disconnected).
0002 The fixing lever switch signal F-KBLK
goes '1' when the front cover is closed
(i.e., the fixing knob is not set).
0001 The rotation speed of the motor has
deviated from a specific value for 0.1
sec or more.
0001 The rotation speed of the waste toner
feeding motor has deviated from a
specific value for 0.1 sec or more (PLL
signal '0').
0002 The waste toner lock detection switch
(SW4) has been pressed for 0.1 sec or
more.
The rotation speed of the motor has deviated
from a specific value for 0.1 sec or more.
• The clock pulses of the pick-up motor
cannot be detected.
• The rotation speed of the motor has deviated
from a specific speed for 0.1 sec or more.
• The rotation speed of the duplexing feeding
motor has deviated from a specific value for
0.1 sec or more (PLL signal '0').
• The rotation speed of the polishing/oil
removing motor has deviated from a specific
value for 0.1 sec or more.
