Question about Xerox DocuPrint 4512 Laser Printer
From the moment i power up the printer he gives the error message "cover open". I've tried to reinstall the drum allready, but that won't help. I thought that in the past the fans immediate started when the printer was powered. Now he "hangs" with the message cover open.
A couple of possibilities.
There are two types of interlock switches on those machines.
First step would be to look all around the machine for any cover that may be slightly ajar.
Then look for broken plastic tabs on those covers that may actuate a switch.
Also some of those switches are actuated by a magnet, and one of the magnets may have come off.
But there is one switch that is not being closed.
Just look carefully for the openings where the switches are located on the machine.
