An E840 error code which occurs shortly after the power switch is turned on.
Workaround :
The E840 code relates to a fixing unit shutter position error condition. The error code can be generated because the shutter motor is not moving the shutter to the sensor detect position or because the shutter position sensor is not detecting the proper movement of the shutter. In this case, the shutter motor had failed because the shutter did not move. The shutter movement was inhibited by a bent Rear Shutter Gear Stopper (Part number FC6-3528-000).
The pictures below show the improper position of the stopper.These pictures below show the proper position of the stopper.The stopper is located on the rear of the Fixing Assembly pictured below.
Accidents don't just happen. They must be carelessly planned. -
ERROR CODE:
E840 (shutter error)
0001 Indicates that the HP sensor signal is not detected when the shutter is operating, after executing 3 retry operations.
0002 The interval of ON-OFF detection by the sensor in response to shutter operation is shorter than a specific time period.
The shutter is set to the appropriate position by driving the shutter motor (stepping motor) for a specific number of steps. A cut-off is found in the periphery
of the shutter gear (front) operating in conjunction with the shutter; the machine checks to see if the shutter is set to the appropriate position with reference
to the output of the shutter HP sensor (PS53), i.e., whether the sensor has detected the cut-off.
[1] Shutter drive gear (front)
[2] Cut-off (for HP detection)
[3] Cut-off (for medium-size paper detection)
[4] Cut-off (for small-size paper detection)
PS53: shutter HP sensor

After mounting the fixing roller, check to be sure that the main thermistor , shutter thermistor , and sub thermistor are parallel and in contact with the fixing roller.
Check the connection of the connector of the shutter motor and the shutter HP sensor.
- check the mounting of the pin used to match the shutter gear phase of the fixing
unit**Knowledge is time consuming, exhausting and costly for a trained Tech.**

Thank you for your help
My fellow techs I want to thank you for the help on the Canon 5570 copier fuser code. As of two days ago I did the adjustment and the customer has not called back, then it must be working great again. thanksComment
