Canon IR7105 Error Code E001-002, E001-004

[tinnyjay]

Hello!
After E001 i changed both thermistors but i am still getting E001-002, E001-004.
I checked fuser connectors but they look ok. The machine can work for 2 hours without any problem, but if you remove fuser unit if you have a missfed, after closing the door i'm getting these codes in general. Sometimes it is working and just shows the code and even i reset, without colding down the fuser, the code dont dissapears. In Copier-Display-Analog i can see the temperatures of FIX-C & FIX-E and when the code is shown, FIX-C temperature shows 28 grade Celcius, even the fuser is very hot.
Any idea please?


PS- the lamps are ok

From SM:

E001-002: The reading of the main thermistor or the sub thermistor is 230 deg C or more for 2 sec or
more. (software detection)


E001-004: The difference in the readings of the main thermistor and the sub thermistor is 50 deg C for
1 sec or more. (main thermistor reading>/=sub thermistor reading)


Check the mounting/soiling of the main thermistor.
Replace the main thermistor.
Replace the sub thermistor.
Replace the AC driver PCB.
Replace the DC controller PCB.

Check for paper smushed(?) inside connector on drawer(on fuser) and at rear inside of machine. If they open drawer with paper hanging out of reg area or delivery area it will tear and when they close drawer it jams paper in connector. Look very carefully

The first think i did is checking the fuser connectors.
Sometimes after the code is shown the machine fall asleep.
