Fuser Unit Error(Error 170-177)

(10-1)  An error occurs right after turning on the power

Confirmation Items

Confirmation Tasks

Action at NG

(10-1-1)  Malfunction of thermistors

Upper thermistor, lower 
thermistor, frame thermistor

 Check to see if the thermistors are short-circuited or 
open.
Check the resistance value through the connector pins 
below the fuser unit. 
(See Subsection 9.1 Check of resistance values (Fuser 
unit.)

 Replace the fuser 
unit. To use a new 
fuser unit on a trial 
basis, use FUSE 
KEEP MODE of the 
System Maintenance 
Menu.

Installed state of fuser unit

Check to see if the fuser unit is securely pushed in to 
such a position that the connector at its lower part is 
plugged in.

Redo the installation 
of the fuser unit.

(10-2)  An error occurs in 1 min. from turning on the power

Confirmation Items

Confirmation Tasks

Action at NG

(10-2-1)  Temperature rise of fuser unit

Thermostat, halogen lamp

 Ensure that the heater control is properly exerted, and 
touch the fuser unit to confirm that it is hot.
If it remains cold, confirm that the resistance between pin 
1 and pin 6 of the connectors (2) measures from several 

Ω

 to several tens of 

Ω

.

Replace the fuser 
unit. To use a new 
fuser unit on a trial 
basis, use FUSE 
KEEP MODE of the 
System Maintenance 
Menu.

(10-2-2)  Temperature rise of fuser unit

Installed state of upper 
thermistor

Check to see if the upper thermistor is installed away 
from its prescribed position, causing the temperature to 
be measured low. Detach the heater cover, and check 
visually for warpage of the sensor, etc.

Replace the fuser 
unit. To use a new 
fuser unit on a trial 
basis, use FUSE 
KEEP MODE of the 
System Maintenance 
Menu.

Installed state of lower 
thermistor

Check to see if the lower thermistor is located away, 
whereas it should be in contact with the unit, causing 
a lower temperature than the prescribed one to be 
detected.

Replace the fuser 
unit. To use a new 
fuser unit on a trial 
basis, use FUSE 
KEEP MODE of the 
System Maintenance 
Menu.

(10-2-3)  AC input for halogen lamp

AC voltage of low-voltage 
power supply

Check to see if the AC voltage for the heater is supplied 
normally.
Between pins 1 and 2 and between pins 3 and 4 of the 
CN connector of the power supply.

Replace the low-
voltage power 
supply.

Heater-on signal delivered 
from PU to low-voltage 
power supply

 Check to see if the heater-on signal turns active at the 
warming-up timing. "L" active while it is ON. 
Pin 11 and pin 12 of the POWER connector of the PU 
PCB (PRF PCB)

Replace the PU 
PCB (PRF PCB).
