Causes
Broken feed clutch coil.
Poor contact in the feed
clutch connector terminals.
Defective harness between
connect PWB and engine/
high voltage PWB.
Defective engine/high volt-
age PWB.
Defective connect PWB.
Poor contact in the eraser
lamp (PWB) connector ter-
minals.
Defective eraser lamp
(PWB).
Defective engine/high volt-
age PWB.
Broken wire in heater lamp.
Thermal cutout triggered.
Broken fuser thermistor.
Dirty sensor part of the
fuser thermistor.
Poor insertion main charger
unit.
Broken main charger wire.
Poor contact of main
charger terminal and high
voltage output terminal on
the engine/high voltage
PWB.
Defective engine/high volt-
age PWB.
Poor insertion developer
unit.
Poor contact of developing
bias terminal spring and
high voltage output termi-
nal (TAB1) on the engine/
high voltage PWB.
Defective engine/high volt-
age PWB.
Check procedures/corrective measures
Check for continuity across the coil. If none, replace the feed
clutch.
Reinsert the connector.
Check for continuity across the harness. If none, replace the char-
ness.
Replace the engine/high voltage PWB (See page P.1-5-14).
Replace the connect PWB.
Reinsert the connector.
Check for continuity. If none, replace the eraser lamp (PWB) (See
page P.1-5-19).
If the eraser lamp (PWB) turns on when YC8-2 on the engine/high
voltage PWB is held low, replace the engine/high voltage PWB
(See page P.1-5-14).
Check for continuity across each heater lamp. If none, replace the
heater lamp (See page P.1-5-10).
Check for continuity across thermal cutout. If none, remove the
cause and replace the thermal cutout (See page P.1-5-10).
Measure the resistance. If it is
(See page P.1-5-10).
Check visually and clean the fuser thermistor sensor parts (See
page P.1-5-10).
(See page P.1-4-15).
(See page P.1-5-6, P.1-5-14).
