اليك اخى علاج كود E0020 فى الالة3170c canon iR
you have fixing trouble, to be specific E002 Insufficient temperature rise of the fixing unit.
The non-contact thermistor fails to
reach standby temperature (normally
190 deg C) within 180 sec after reaching
180 deg C.
Try to clear the error by entering service mode:
press *
Press the 2 and 8 keys of the keypad at the same time.
press *
navigate trough service mode : COPIER>FUNCTION>CLEAR >ERR
If these doesnt helps, replace entire fixing assy, its most reliable way to get rid of complications.
Hope that helps!
