The exposure lamp
does not turn off.
Defective inverter PCB. If the exposure lamp does not turn off with YC1-1 and YC1-6 on
the inverter PCB high, replace the inverter PCB.
Defective engine PCB. If YC17-1 and YC17-6 on the engine PCB are always low, replace
the engine PCB.
(13)
The fixing heater
does not turn on
(C6000).
Broken wire in fixing heater
M or S.
Check for continuity across each heater. If none, replace the
heater M or S.
Fixing thermostat triggered. Check for continuity across thermostat. If none, remove the cause
and replace the thermostat.
(14)
The fixing heater
does not turn off.
Broken fixing thermistor
wire.
Measure the resistance. If it is
∞ Ω, replace the fixing thermistor.
Dirty sensor part of the fix-
ing thermistor.
Check visually and clean the thermistor sensor parts.

The original size is
not detected.
Defective original detection
switch.
If the level of YC18-5 on the engine PCB does not change when
the original detection switch is turned on and off, replace the origi-
nal detection switch.
(19)
The original size is
not detected cor-
rectly.
Original is not placed cor-
rectly.
Check the original and correct if necessary.
Poor contact in the original
size detection sensor con-
nector terminals.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
