Hi
C440 error on device problem toshiba e-studio 456 se
Please let me correct code.
400-08 code did not work on 456
Thanks

This is fuser judgment abnormality.
usally you can just reset the code and the machine willl work.

to reset the code do the following:
1. Turn the mahine off from the main power switch (on front or side depending on the model)
2. hold down the '0' and '8' keys on the keypad and turn the machine back on.
3. when the machin starts and the startup screen is done enter 400 and press start.
4. u will see the same number twice. write this number down and keep it in case the error comes back.
5. now press the '0' key and the enter button on the display.
6. turn power off wait 5 sec and turn it back on normally.
this clears the code, if the code returns you can try repeating this but most likely you will need to call for service and give them the error code and the number you wrote down

There really are 1000 reasons the check engine light is coming on. If you keep resetting it and it comes back on, and it is not affecting the engines performance it is more than likely a faulty sensor. But thats just 1 of the many reasons. They want to keep you coming back so unless you tell them to fix it. They are going to be very vague. Get the obdII software and reader is the best thing I can tell you. Then you can read the code that is tripping the CEL. Hope it helps!

First of all check what is sub code with this .if it is not showing code press clear & 8 key at same time .code will bi shown .if no code just reset pm cycle count.MIAN AKHLAQ
