Here is other messages that shows on the printer

1. Ink Cartridge(s) Problem The following Ink Cartridges must be replaced. I have brand new ink cartridges.

2. It was printing about 2 weeks ago, when I replaced the empty ink cartridge. Then, it stopped. I called HP and they sent another one. Now, it will not accept the new cartridge. 

3. I have downloaded print drivers from HP.com and I have uninstalled and reinstalled the printer software about 4x.

I bought the HP OfficeJet Pro 8620 printer in 2015 and up until december 2019 it has worked perfectly. One day out of the blue, I recieved this error message: “The printhead appears to be missing, not detected, or incorrectly installed. Error code 0xc19a0023" . I reseated the printhead one time and the printer worked until next day, when the same error appeared. I followed HP’s troubleshooting steps 1. reset printer 2. reseat printhead 3 times 3. updating firmware, but no luck. I’ve disassembled the printhead and cleaned the contacts on PC board. I ordered this cleaning solution and cleaned the printhead, both soaking in the solution for some time and pushing the solution through. No luck. I then went on to buy this new print head from eBay, but the new one instantly gave the same error message.

Then I continued to troubleshoot some more. Since the new printhead failed I thought maybe the problem is in the printhead carriage inside the printer. I disassembled it and cleaned the contacts on the PC board. (This one is also possible to buy on aliexpress , but I’ve not done it). Everything looks ok. All the pins are undamaged. I’ve reset the CMOS battery on the main board, disconnected all cables and checked the cables specificly for the printhead carriage. I don’t have the equipment or knowledge to test if the cables actually work, but everything looks ok. Still getting the error message.

One last thing that I came by today on this page is that it might be the unoriginal ink that I installed for the first time last time I replaced my cartridges (about 3 months ago, I switched the last color from original HP to unoriginal). Could it really be the problem? Is it still worth a try to buy new original HP cartridges and will it even fix the problem? Or is the damage done already and not reversable? I’m a bit hesitant to invest more on this printer since I already blew up 72 EUR for the printhead…. Returning the printhead to China from where I live costs almost 40 EUR so it’s not worth the refund.

EDIT: I found an official statement from HP about a new firmware update removing Dynamic Security Feature which makes the printer fail when unoriginal ink is installed. However they explicitly say it’s only connected to a cartridge error message. Other error messages are not related. So in theory I’ve already solved this issue, when I updated my printer to the newest firmware early in the troubleshooting process. Both printheads give the same error message. This decreses my belief in buying new original ink to fix the problem…

EDIT 2: I found the old original HP empty cartridges I had before and installed them just to see if it would remove the error, but it didn’t. So now I don’t have to waste money on buying new ink at least…

Or am I missing something else? Thanks for helping out!

I have a LaserJet P3005dn which I am very happy with. A few weeks ago, however, it started jamming and jamming frequently. About every three to five pages it jams in the printer with the message 13.02.00 (jam in top cover area). I clear it by removing the toner, removing the paper, then continuing.

One clue what is happening is this: Right as it jams an empty paper is ejected (about halfways, usually) while another empty paper is stuck inside.

I have the service manual but really do not know where to start, i.e., what is the most likely cause here and what should I check first? Any help would be greatly appreciated.

Thank you!

​Message:

"Hi, I have an HP LaserJet Pro M402dne. When I turn it on, the fan starts spinning for a few seconds, but then I hear a loud 'double click' or grinding noise (clack-clack sound). Immediately after this sound, the fan stops spinning and the printer stays idle.

​I suspect it might be a stuck solenoid or a fuser gear issue, but I’m not sure. What is the most likely cause for this specific 'double click' sound on startup, and how can I fix it?

​Thank you!"
