Ch means the side door is not closed or the toner is not installed correctly.

this sounds like you have a jam in your fuser unit.To remove this jam open the door at the left hand side,you should see a green lever to the back end lift up and take paper out,after doing this you then have to reset this error code.To enter service mode press P interupt C interupt key in 14 press start key then press CA.Photocopier should reboot if this does work then you need to get your service engineer out
