Thank you for sharing. Is there a Part 2?

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

[tomtin]

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.

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

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!

[AG-luxv]

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....

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.

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.

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

[mohamadallouch]

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

[ivoandonov]

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.

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..

[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

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.

[iliaszissiadis]

[Anthony.VTangi-uceb]

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

[ashleylasaventurasuk]

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

[liad]

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