Fix HP 7612 Printhead Missing or Failed Problem - Part One - Remove and Install

[@iamrobinson]

Thank you for sharing. Is there a Part 2?

[@AtomkeySinclair]

Hey - removing the top of the print head and turning it over to insert the ribbon cables was a great idea - thanks!

[@tomtin2001]

Didn't he forget to remove the plastic cover that he placed over the print head to protect it. I didn't see him pull the plastic off and he replaced the print head without removing it? Probably the reason many reported that his fix didn't work.

[@StevenGrant_Photographer]

yes for sure he left the tape and film on printhead but i know for sure he knows what he is doing in regards to printers.

[@AG-lu1xv]

Thanks very much - quite helpful - I was finally able to get printhead out of its carriage, and clean everything. Unfortunately, after all the efforts, my 7612 is still giving me the "Ink System failure" message, and I can't get past it. I haven't found anything to help further with that....

[@eduardoferraz6907]

Better buy a new PrintHead for $25 at eBay

[@dgshen]

Maybe the thin transparent plastic is leaking air. Try to find some glue to seal it airtight again.

[@kmah1974]

Can you please post a link to part two? Annoying as the aim is to fix the problem but the video ends as it started - with a broken printer!

[@nlambuca]

On this printer I am getting carrier jam but carrier moves. I cleaned the print head. Not sure I pushed it from park position... would that cause the problem? How to restore park position (cover on print nozzles) ? Thanks

[@paulmohney5450]

i would bet those contacts are a couple of microns of gold plating. Cleaning themwith an abrasive, is a good way to ruin them. Like the contacts on my Camera lenses, I would suggest using Isoppropyl alcohol, and a cotton tipped swab. That's what canon reccomends

[@DirkCilliers]

Part 2 Please, i have the same issue

[@fbatista1973]

I got one printer like this for free, and it has the same error. Have you already published part 2 of this video? I didn't find it.

[@RafaelPernia]

same here. Have you figured it out? thanks

[@jonneal2287]

I recently change ink to a generic brand.. then didn't use the printer for a week.. when I came back I got this error- I watched this but rather than taking it ALL apart, (Cables air lines etc etc) I just lifted the up the print head and saw ink all over the bottom.. so I wiped it with alcohol and it seemed to be fine... and I switched back to HP ink.

[@freemangray8279]

There are 2 wide cables at back of printer head do both ge connected or just the upper one...the cabkes are on the left of printer head..

[@mohamadallouch4239]

I have cleaned printhead but still same problem. What can i do to fix it?

[@nemanjaradonjic6620]

Hey guys I have an Hp 6700 premium printer and I have the same problem as in the video. I took out the printer head and cleaned it but I still have the same problem, the printer says that the printer head was not detected, missing or incorrectly installed.I need a little help because i'm not sure if it's a broken print head or something else.

[@ivoandonov117]

Let me tell you guys, gals and whatever what worked for me after watching and reading any possible video, document and forum on the net: I sucked with a syringe in the pressure port of the printer. Then after power up one can clearly hear the short pssss hissing sound of air pressure being released when the head moves out of its home position. And there it is - the printer is working again. Again - I sucked in the PRINTER pressure port, not the head's mating hoses side. It seems the pressure pump was stuck or there was some obsticle in the pump's hose. Probably a stuck motor though.

[@geglogu]

Ivo Andonov what’s a pressure port?

[@Dogzbrk]

Where is the pressure port?

[@dgshen]

@@geglogu I guess he refered to the upper part of cartiage which has springs attached to it. And if you hear unusual high hissing sound during the clean up, there must be some air leaking from the thin transparent pastic seal. You may need to find some glue to seal it back again.

[@zgr44]

ok, and how did you sort the issue ?

[@angelawicks7727]

I enjoyed the music, broaden your horizon. I found the video great for cleaning the printhead, however, a loss for not resolving the problem.

[@nokke36]

Indeed, useless video, also for me it does not resolve the problem

[@fbatista1973]

i had the same issue on my HP Officejet 7612. I had tried all sorts of reset (partial reset, OOB reset), except the full reset (no setup cartdriges available), but nothing was working for me. I have even tried to add the aluminum foil on the printhead circuit, but it did not help either. So, with nothing to lose, I entered in the service menu and decided to try the option “MFG”. A grid appeared on the print screen, and I let it run for about 5 seconds, then I unplugged the power cord from the printer. After that, I reconnected the power cord, and the printer started working fine again!

[@jigsawmultimedia1970]

I have the same printer and I am having these issues. How did you access the service menu

[@BIZEB]

Holy shit, this actually works.

[@markvanvlerken5507]

@@jigsawmultimedia1970 In standby mode: - unplug power cable - press power button - keep it pressed while plugging power cable - keep it pressed for 10 sec - then by the screen press in sequence : home, back, home, home

[@adriank2959]

I DON'T SEE MFG MODE UNDER SERVICE MENU

[@edipopetroleo]

It didn't work for me :''(

[@nflmonica]

He forgot to remove that big piece of tape he put on the back.. I dont know???

[@asuryadi7]

Right

[@kosh3996]

Sure ,otherwise it would have worked I guess.

[@ashleylasaventurasuk1792]

My printer prints are black stripes, I give the option to clean the head, it prints white stripes for several times and then returns to print the images with black stripes. I have tried to align it but it tells me that the alignment cannot be completed. Should I replace my printhead or what can I do? Thanks

[@shabbiransari1646]

I have tried same but not working , it's 20% chance to solved printhead issue in this printer.

[@Pilifonia676]

Very clear and detailed instruction. One of the better videos on utubr

Thanks so much for subscribing to my channel and for taking the time to comment! Your support means the world to me, and every subscriber brings me closer to my goal of reaching 100k. It’s been an 8-year journey, and I’m halfway there, but I’m committed to creating high-quality content and helping subscribers like you. I’ll always do my best to answer your questions as quickly as I can, but if I miss something, feel free to email me directly at [e-mail]. From what you’ve described, the issue is most likely with the printhead itself. We’ve found in most cases like this that it’s a malfunctioning printhead rather than the cables causing the problem. Even though you’ve replaced the cables and cleaned all the contacts, refurbished printheads from sources like AliExpress can sometimes have underlying issues that make them unreliable, even if they initially seem fine. I understand how frustrating this can be, especially after spending so much time and money trying to resolve the issue. My advice would be to try sourcing a new printhead from a reliable seller to rule out a hardware issue completely. If you need more specific guidance, feel free to reach out-I'll do my best to help! Thanks again for your support, and good luck with your printer!

[@subratapaul6398]

sir pls. send a video for hp desinejet (plotter) t830 and 730 how to clean cloged head with a machine and without machine

[@malaquai1]

Ok, where is the part II ?

[@boinger5]

And I still have the printer carriage cannot move error & Ink system failure. I'll look for another video. I already bought a new printer head with the same problem

[@liad1706]

Maybe next time give a heads up regarding the two cables that get disconnected the moment you pick the ink head up!!!!!

[@MMm-ex9jf]

where are part 2

[@oopsss47]

Real solution would be interesting! Part 2? Or is it like it is (was) widely discussed, that HP made those printers stop working once you had inserted non-HP-ink (by firmware-updates) - basically a criminal act and there were several trials dealing with this "policy", obviously with not too many results - will never buy something from HP again ...

[@326147]

There not brass plates they're gold plated... or they were before you sanded them.

[@BCHTechnologies]

Okay, gold.

[@rokketron]

It didn`t work then?

[@EternalBlox777]

Poderia me informar se alguém resolveu esses problema?

Printhead Missing or Failed Problem in HP Designjet T830

[@BCHTechnologies]

Check if the printhead has good contact with the printer. If it does, then the printhead may be fried.

[@vetorengenharia2002]

Friend! I'm in Brazil. I have a hp T730 that has the same problem. Did you fix your print head or did you have to buy another one?

[@najibsafsafi5596]

You'd better have the steady hands and keen eyes of a neurosurgeon before taking this on...

[@kriley9386]

After all this, the HP still didn’t work. So I trashed it and bought a new wide paper printer.
