Abnormally low fixing unit thermis-
tor temperature
• The fixing thermistor detects tempera-
ture lower than 100 °C/212 °F for 10
s.
• When fixing heater M is on, the tem-
perature of the fixing thermistor is
lower than 40 °C/104 °F and contin-
ues to drop for 24 s. (If the tempera-
ture in the copier is 10 °C/50 °F or
less when power is turned on.)
• When fixing heater M is on, the tem-
perature of the fixing thermistor is
lower than 40 °C/104 °F and contin-
ues to drop for 14 s. (If the tempera-
ture in the copier is higher than 10 °C/
50 °F when power is turned on.)
Fixing unit connector insertion prob-
lem
• Absence of the fixing unit is detected
continuously for 1500 ms while there
is no error on the copier.
Broken fixing unit thermistor wire
• The fixing temperature remains at 0
°C/32 °F for 30 s continuously when
the fixing heater is on.
Toner sensor problem
• While the toner container sensor is
on, the toner sensor in the developing
unit does not turn on after the toner
sensor turns off and toner is replen-
ished from the toner container.
Image formation unit connector in-
sertion problem
• Absence of the image formation unit
is detected continuously for 1500 ms
while there is no error on the copier.

Check the connection of connector CN10
on the main PCB and the continuity across
the connector terminals. Repair or replace
if necessary.
Measure the resistance. If it is ∞ Ω, replace
the fixing unit thermistor.
Check and reinstall if necessary.
Check for continuity. If none, replace the
fixing unit thermostat.
Check and reinstall if necessary.
Check for continuity. If none, replace the
fixing unit heater M or S.
Reinsert the fixing unit connector if neces-
sary.
Replace the fixing unit.
