Deskjet 3070A Printer stop printing black ink

[boumbh]

A few days ago, I started experiencing black ink problem with my Deskjet 3070A, something like this:

I changed the cartdridge but that did not fix it. I ran a print quality diagnostic which gave me something like this:

I cleaned the print heads (all three levels). Then it got worse, black text was almost unreadable.

Now, black ink does not even get out. The vent on the cartdridge seems allright. When I shake it I can hear it is full of ink. The software tells me that levels are at the highest.

Note: The printer is one year old (guaranty just expired), I never used a third party cartdridge, only HP genuine cartdridges.

Then I removed all the plastic and glue on the top of it, blew a bit into the vent and ink came down from the cartdridge.

Is the printhead stuck?

I’m very annoyed I really need a printer at home for my work.

Is there a way to remove the printhead assembly? I could not find any latch handle... And what is the point of these weird screws? The printer should be sold with the corresponding wrench... How am I supposed to troubleshot the device ^^' ?

Before posting I searched for similar topics, I found a lot of them but no relevant solution. Am I supposed to throw the printer away already? :'-(

Hi Boumbh,

I understand that you're printer is not printing black ink.  I would take a look at the document below.  

Let me know how it goes.

Hi Garytech1,

I did it twice already, that’s where I found some of the images of my previous post.

Thanks for your support. I think I was very unlucky with this failure and I need to buy an other device now... with 3 years extended warranty this time .

Regards.

Wow. What a surprise (not)

this is the 5th thread on here today with more than one user complaing of the same problem- black suddenly stopping.

here is another thread

http://h30434.www3.hp.com/t5/Printing-Issues-Troubleshooting/FORUM-COMPLETE-READY-FOR-DELETION/m-p/2...

right now it has a lot of traffic but they are looking to delete it-

I have the same issue with my HP photsmart 5512.

even bought a multi=pack of brand new black, xl, but it is not working. 

Please help, HP!

this looks exactly like my sheets when I lost my black earlier today! no, nothing, not a drop!

Maybe I should have tried and opened my 3070A... But I wasted two XL black cartridges and that made me going a bit nuts, I didn’t want to deal with the printer again, and I really needed to print.

I tried but could not sell the printer for 10€ so I ditched it.

I searched for a laser black and white printer for I thought it was less prone to planned obsolescence.

Then I bought a HP Officejet Pro 8600 (cheap cheap ink), and I applied to a 3 years warranty.

I still only trust HP for the good value for money of the supplies.

Still, some marks of hypocrisy annoy me a bit. The worst one is the B&W option which is hidden behind three levels of option screens and that you must tick every time you print, they sure did it on purpose and it’s kind of dishonest.

Same problem with my 3070A, black stopped printing. New XL ink cartridges installed for all colors (all were displayed as nearly empty), worth Eur 58 ... no improvement. All standard advice followed ... no improvement.

Device is just out of warranty.

Thanks HP for this exactly planned life span and congratulations for making me pay even the last set of XL cartridges! Maybe in the future the remaining device lifetime in days can be shown on the little display?

Will buy me a printer of another brand tomorrow!

Bought two of these 3070A for my parents last year and this must be the most unreliable printer ever.  Latest replacement(#4) failed to print black after just 3 weeks. It also stupidly demands all the cartridges to be in before starting to print in the first place, even if only black is needed. A horrible waste of time and money.  

Have to mention also my dad died in traffic on his way back from the ink store getting black 364XL cartridge for it, needless to say, in vain. :catfrustrated:
