Defective ink cartridge 934xl

[annoyed32081]

I am having a problem also with an HP934XL cartridge. I installed it on 12/21/18 and the warranty is good until May 2020. The printer shows that it's still about 2/3 full. Nothing I've done (such as cleaning the printheads 6 times) will cause the printer to print black. How do I file a warranty claim? I've spent over 3 hours troubleshooting and then trying to locate a way online to submit a warranty claim for the ink cartridge.

I gave up with my warranty claim on cartridge. They just went with warranty on printer, which mine is out of. I spent too much time troubleshooting on my own. Too much time trying to say it was cartridge and not printer. I actually ignored my printer and cartridge for like a month and miraculously the cartridge now works. However, I’m almost out of ink on this one and worried what will happen when I go to change this one for a new one.

Such a waste of money. I just installed a second 934 XL black cartridge and it is also not printing any black even after cleaning the printhead three times. I had bought a two pack of the cartridges and assumed perhaps the first cartridge was a dud but now I’m thinking it’s some other problem and not the cartridge itself

Please read this post then provide some details.  What printer model? What operating system?  Are there any error messages on the printer or computer screen?

The troubleshooting steps in the document here may help resolve black not printing on the Officejet 6830, your printer may be similar.  

If the standard troubleshooting did not resolve black not printing I would suggest removing the black cartridge.  Turn it over and examine the area around the ink port.  There are four orange plastic spots, left over from the protective cap.  Make sure these are flush with the cartridge body, if not carefully trim them flush.  If the plastic nubs protrude they can prevent the cartridge from seating properly.  Before replacing the cartridge in the printer dribble a few (maybe four) drops of hot water into the ink port in the printer and two drops into the ink port on the cartridge then snap the cartridge back in position.  

It may also help to manually clean the printhead as described in the post here.

I have also seen cases where leaving the printer overnight after the cleaning cycles allows black to recover.

If none of the above restores black printing your printer will likely require repair or replacement.
