Dirty sensor part of the
fixing thermistor.
Broken main charger wire.

Check for continuity across the coil. If none, replace the drawer
paper feed clutch.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U032 and check if YC8-3 on the drawer
main PCB goes low. If not, replace the drawer main PCB.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Check for continuity. If none, replace the cleaning lamp.
If the cleaning lamp turns on when YC3-7,8 on the engine PCB
is held low, replace the engine PCB.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U061 and check if the exposure lamp
turns on with YC1-1 and YC1-6 on the inverter PCB go low. If
not, replace the inverter PCB.
Run maintenance item U061 and check if YC17-1 and YC17-6
on the engine PCB goes low. If not, replace the engine PCB.
If the exposure lamp does not turn off with YC1-1 and YC1-6 on
the inverter PCB high, replace the inverter PCB.
If YC17-1 and YC17-6 on the engine PCB are always low, re-
place the engine PCB.
Check for continuity across each heater. If none, replace the
heater M or S.
Check for continuity across thermostat. If none, remove the
cause and replace the thermostat.
Measure the resistance. If it is ∞ Ω, replace the fixing thermistor.
Check visually and clean the thermistor sensor parts.
