Question about HP LaserJet 2420 Printer
The printer has an error saying close top Cover. The cover is closed. What to do?
Start by trying this.
Open the cover and look around for openings in the where the cover closes. In those openings there are interlock switches. 1 of 2 things have happened.
1, The switch may have become dislodged.
2. Look on the cover you have opened for actuators, ( pieces of plastic sticking out) that would go into those holes to turn the switch on when closed. Those often break off.
One of those 2 items is your problem, The switch is just not being actuated properly.
Make sure nothing is binding the cover also.
