A friend of mine is having trouble with his copier. On the message panel it is displaying: door covers open. close covers on relay. I have been over the machine checking all the door covers and even activating the sensors to try and get it to register they are closed but to no avail. Any ideas ? cheers in advance. Ray.
I post a solution for this problem see: www.fixya.com/support/t2748127-false_door_open_reading_aficio_350
- Check the fuse FU1 y FU2 in the power supply board FU1 display open door Without
saying as.

laser also can cause the fault of open door,
cut or badly connected this also it can be indicate door opened without indicating
as.
El
cable plano del laser cortado o mal conectado, tambien puede provocar
la falla de puerta abierta sin indicar cual de ellas está abierta.

First check the small door below the duplex unit on right side, if that is closed porperly and all others are also, it could indicate a blown fuse condition.
