I had the same problem. Chatted with HP technician who indicated the repair would cost more than a new printer. I asked for access to service manual but was told there is none. I was able to fix it myself by using a hacksaw blade to cut across the dark plastic bridge area that hides the open cover sensor. After removing this section of plastic I was able to see the wiring plug attached to the faulty sensor. All you have to do is jumper the two colored wires together (ignore the black wire) and the cover open error will go away. Make sure you clean out all the debris you created from cutting out the plastic section before powering it up. I placed a clean rag inside the printer under this area before cutting to catch most of the plastic "sawdust." It wasn't pretty, but it was better than throwing the printer away and buying a new one. It didn't take more than a few minutes to fix, and with the cover down, you don't even know it's been "hacked."

Try re-seating the ink cartridges and printing a test page. Those were new HP cartridges, right? Not some garbage from a ink cartridge refiller off ebay?

Printer lid open light is coming on when printer lid is closed


The printer lid error can appear if any of the following are true:
- top lid is open
- rear duplexer or flat panel is not installed correctly
- cartridge bay area door is open

All of these conditions are detected by a series of sensors or circuits in the printer design so with regard to the lid and cartridge bad door you need to make sure that nothing has broken off that closes the switch.

I'd lay odds that it's most likey the rear panel/duplex unit. I'd recommend taking this out as per the manuals instructions and then reinserting it, carefully so that it fits in place properly.

Hope that solves your problem.

HP Officejet Pro K850 printing problem


Soon after I posted the problem on this site, I went to different margin setting windows and they all appeared correct. I tried another test page and noticed the printer was off. I turned it back on and it worked perfectly. I had previously unplugged the power and cable and rebooted the system several times to no avail. I also have an HP Officejet 7410 All-In-One so I didn't need the other for everyday operations, just preferred it.
