TECH TIP: HP OfficeJet Printhead Cleaning: https://www.youtube.com/watch?v=1ZqJSerkGu4

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.
