SOURCE: ERROR E840 FOR CANON IR5570
This is a fuser shutter error. Subcode 0001 is that the shutter is not being detected by the shutter sensor. 0002 is that the shutter is moving but on/off detection timing is off. When the copier is powered up you should here this shutter trying to find the home position. If the error occurs then, most likely the sensor is bad or unplugged. Have you done any fixing repairs recently and got this error?
