The power light and all color cartridges lights are blinking. According to HP support such light pattern means that those "cartridges are faulty or need attention" and the solution is:

  • reinsert cartridge, or
  • replace the cartridge

Through out the years, whenever there was a cartridge issue I just had to override it (resume button or power+resume x3). Unfortunately, now is different (although there is no visible damage or other known reason). Even cleaning the gold contacts of the CISS chip made any difference.


  • What might be causing such issue?
  • Any way to solve it without replacing the cartridges with new ones (extremely expensive)?

Additional Notes


I've already executed HP Officejet Pro Firmware. The firmware was already the latest one, even so I required it to be updated.


Damaged/dirty component/sensor

I've already cleaned them with isopropil alkohol.


Bad cartridge

They were all installed in 2010. Never had any issue with them. Recently all 3 decided to fail simultaneously. However, there are no visual damage and the gold contacts were also cleaned with isopropil alkohol.

I've also executed HP Print and Scan Doctor for Windows which shows:

|  black | yellow  | magenta | cyan   |
| ready | failure | failure | failure |

However, the sensors can precisely pinpoint whether the cartridge is missing or is a failure. For example, removing only the magenta would show:

|  black | yellow  | magenta | cyan   |
| ready | failure | missing | failure |


Cartridge compartment

I've already check that several times: cartridges compartment.


Bottom of the cartridges

I've already check that several times also: bottom view of cartridges.


Hard Reset*
(*) Fully power cycle the machine by shutting it down, take out the cartridges, unplug it from the power source, and pressing the power button 5-10 times, and then starting it back up.

I've already tried that with several different black cartridges and several different black/yellow printheads: cartridges and printheads.

  • You might need to do a hard reset (see ifixit.com/Answers/View/443001/…). If that doesn't help, the ink cartridge chips may have gotten corrupted, even though the cartridges are otherwise good. HP might replace them under warranty (there is actually a warranty on each cartridge). I would talk to HP before buying a new set of cartridges. They may have specific diagnostics or fixes to try, or may be willing to send some starter cartridges to see if the printer is bad (or they might want you to send the printer in for repair). – fixer1234 Dec 15 '18 at 23:53
  • @fixer1234 "You might need to do a hard reset" Already tried that several times. Take a look at the notes I've just edited in the original question. – Mark Messa Dec 16 '18 at 0:23
  • @fixer1234 "HP might replace them under warranty" This printer and its color cartridges are from 2010. I'm pretty sure there is no more warranty. – Mark Messa Dec 16 '18 at 0:24
  • @fixer1234 "I would talk to HP before buying a new set of cartridges." I've already tried that. Unfortunately, HP does not provide support for out of warranty devices. – Mark Messa Dec 16 '18 at 0:25
  • I answered based on the information in the question and early comments. Your last comments indicate that the situation isn't quite as described. It sounds now like you installed some cartridges in 2010 and have been refilling them ever since. We need to work from an accurate set of facts, because the underlying problems could be different. You can't refill cartridges forever. Also, the chips could have become corrupted, and it isn't clear whether you've disabled the chips. It's possible that the printer electronics or firmware is the issue. (cont'd) – fixer1234 Dec 16 '18 at 3:00
