HP OfficeJet Pro 8620 Printer - Missing or Failed Printhead

TECH TIP: HP OfficeJet Printhead Cleaning: • HP OfficeJet Pro 8020 ...
---
For the #HP #OfficeJet #Pro 8620 #printer, if you observe a #missing or #failed #printhead #error then it is possible that the internal PRINTHEAD may have a bent or #damaged contact #pin or pins. When the cartridge is installed these pins make contact with the #Internal #PRINTHEAD. If there is poor electrical continuity contact between pins and the cartridge's #electronic #chip then errors such as #damaged, #failure or #missing will be displayed, in some cases a printhead failure error may be displayed.
To verify pin condition, remove all 4 ink cartridges and using a flash light, carefully inspect the internal PRINTHEAD contact pins for visible damage.
Each pin should be protruding outwards as shown. If the pin is bent down, it is possible to gently pry it back up with a small screwdriver. If a pin is broken, then the #HP8620 PRINTHEAD will need to be replaced.
Other printer error messages which could signify a PRINTHEAD problem include “Ink Cartridge #Failure”, “Cartridge Damaged”, “Cartridges Missing” or “The following cartridges are #not #intended for use in this Printer”.
-----
Note: If you have installed a refilled or aftermarket #HP950 or #HP951 ink cartridge into your HP #OfficeJet Pro #printer and observe the error message “Ink #Cartridge #Depleted”, " #Cartridges Depleted" or “ #Ink #System #Failure “, this is usually caused by one, or more, of the #HP 950/951 ink cartridges not having enough ink inside. In most cases one of the cartridges is empty but the cartridge’s electronic smart chip is telling the printer it has a full ink load.
An "Ink System Failure" #error #condition is generated due to air being ingested into the printer’s internal PRINTHEAD assembly and the presence of ink is not being detected via #sensors inside the ink cartridge. Thus as a #safety precaution to protect the printer, the printer is shutdown to avoid burning out hundreds of small electronic #thermal ink #firing #nozzles inside the PRINTHEAD assembly.
Remove all four #HP950 #HP951 (or #HP950XL / #HP951XL) #ink #cartridges and weigh them with a scale to help determine which cartridge has an inadequate amount of ink inside. The lightest ink cartridge, in comparison to other available full cartridges, will usually reveal the likely culprit. Replace suspect cartridge, or all four ink cartridges, with brand #new HP #original ink cartridges to completely eliminate root cause of both ink volume and attached chip compatibility.

The average person may agree that finding low cost #ink or #cartridges is top of the list when searching, i.e. #HP950 or #HP951 #inkjet #printer #cartridges, since originally branded ink is quite #expensive. Is refilling your #HP #OfficeJetPro ink cartridges, purchasing aftermarket 3rd party cartridges or signing up for HP’s #Instant Ink #subscription #program the better deal? Let’s look at the #HP Instant Ink program and real world numbers based on my own experience over the past few years.

You just saved me a few hundred dollars. I dismantled the print head and bent the pin back. The error I was getting was that an ink cartridge was missing, however, it had a brand new one installed.

[@LaurralynMike]

Very glad to hear this - nice job! (and yes, need to be careful when bending those pins back). Again, way to go!!! :-). UH

[@lakelady68]

I got the 'Missing or failed Printhead' 'the printhead appears to be missing, not detected, or incorrectly installed'-- bit confused because I printed something and went to print more and this msg came up..

[@LaurralynMike]

Remove the printhead and thoroughly clean the printhead electrical surfaces and then reinstall to see if the error clears.

What does error code 0xc19a0010 for "missing or failed printhead" on Officejet Pro 8620 signify ? Specifically, what part of printhead is at fault? Thanks for your help in advance.

[@LaurralynMike]

Electrical connectivity to the printhead....thoroughly clean PH surfaces and reinstall.

[@OldRatbeard]

If the pins seem fine but we're still getting the message that the printhead is either missing, failed, or not installed properly, what else should we check? I've removed the printhead and checked the pins, reseated the ink cartridges, and rebooted afterwards but it's still giving the same error.

[@LaurralynMike]

Hi OR, Did you thoroughly clean all of the electrical contact surfaces on the printhead assembly using warm soapy water? Also, ensure you wipe all of the ink residue off of the bottom nozzle plate surface (i.e. this is where the 80K+ ink drops are fired from per second during printing); while doing so check for any delamination of the nozzle plate surfaces (i.e. ink penetrating the outside edges of the nozzle plate, which could allow for ink intrusion beneath the plate surface, etc.). UH

I also have cleaned everything nothing is bent and it hasn’t been touched since it printed something 4 hours ago for me 🤷‍♀️

[@john4639]

John, do you have a reputable source for HP print heads?

[@LaurralynMike]

Hi John, while you could get an aftermarket part via Alibaba.com (for about 30% cheaper) you are much safer going with HP.com directly since you get a 90 day warranty on the part. Here is the hp support page which provides direct links for ordering: support.hp.com/us-en/document/c04091615 Good Luck! UH

[@LaurralynMike]

Internet feed or server error via KZbin most likely...close and then open the browser will usually fix this issue. UH

[@BarnabasJunction]

checked and tried this several times now without success, my printer was working 100% fine until i replaced my low (shop bought) cartridges with HP Instant Ink cartridges. they have now killed my printhead and refusing to fix it. #HPKILLERINK

[@LaurralynMike]

Yikes! :). UH

[@giovannidepetris6335]

only problems with Hp printers never buy another one again

[@LaurralynMike]

Yes, can be frustrating with all the chip encryption used these days.
