How do I remove the printer cover?
An envelope has jammed inside the printer and is not accessible from the front or back of the machine.

Here is a document from HP telling you how to get rid of paper jams on the c4780.
Good luck!

Thanks for this. The document reminded me about dropping the cartridge door. This solved the problem. Thanks again.
Good diagnosis.+
0ur printer makes a loud banging noise before it prints -the noise seems to be coming from
ink cartiages when they travel to the right side ?
