Canon IR3100cn Error Code e000004-001

with that low amt. of prints- i would check this first--
Check to see if MS 3 is fully actuated with right door opened.

Remove the 2 screws holding the metal switch actuating cover (fig 13 pg 2-14 in parts catalog)which is located behind the plastic inner cover-

Also check if the front cover actuator has come into contact with and detached the front cover sensor PS22. The sensor can come in contact with the sensor mount, causing the 5V line to be shorted.
this can damage the sensor---------------------


When you remove the 2 screws and begin to move the metal cover you will notice the gear and spring mechanism will release MS3 actuating arm.
Re-position the metal cover, replace the screws, plastic cover and check that the mechanical operation of opening and closing the Right Door are now correct.

Check the door actuating switch MS3. If the switch is in the fully actuated state even with the right door open this code will been present.
Loosen or remove the 2 screws holding the metal switch actuating cover which is located behind the plastic inner cover , & repositioning the metal cover
