Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
How old is the printer?
Does it get power without a surge protector?
When you open any of the doors, does the clicking stop at any point ? if so determine what door opening stops the clicking.
Also try removing all paper from both paper trays. And try clearing the printer's queue on the computer that prints to it. See if either stops the clicking.
And, try opening the printer, and re-seating the cartridge(s), one at a time. See if that does it, also.
And, try leaving it Off long enough to cool down... which takes as much as an hour to cool thoroughly, being a laser printer. Let me know how it goes, and I will advise you further as appropriate to what you find out.
