The printer can print in color, but it does not print black text. I have changed the ink cartridge and there appears to be no issue with the printhead.

My HP OfficeJet L7680 just stopped printing ANYTHING black. I change the black cartridge twice.I cleaned the printer heads, aligned it and still it will no longer print anyhting in black. When I do a test...


It sounds like your printer setup has changed to generating black by MIXING the color inks... if you run out of the cyan and yellow it will do red in spite of how many changes you make of the black cartridge.

Investigate the setup for the printer to make sure it is set for black from the black cartridge.

HP Officejet Pro L7650 Print head problem


The reason why the printer refuses to print if you get low on one or more colors is that the system runs off negative pressure through the ink lines to the print head. If you were able to continue printing with an empty cartridge you could get air in the respective ink line, disrupt the negative pressure, make it so that that color will no longer print, and require you to get the printer serviced to fix the problem. I own a Cartridge World ink refilling store and I feel this is a good machine (compared to some of the others out there). The only down side with this type of machine is the print heads expiring or getting clogged as you are experiencing. The reason the black is clogged and not the other colors is that the black ink is pigment based and the colors are dye based. The pigment based inks do tend to clog print heads over time. You can try to rehydrate the print head with warm distilled water. if you can't get it working to your satisfaction you can buy a new black/yellow print head for $72. With this type of printer you should print at least one black and white and one color document per week to keep the print heads fresh. If they sit too long without ink flowing through them then they can get clogged and print poorly. I hope this helps belay some of the resentment you hold towards your printer.

L7680 printer was working fine. It stopped printing black but will print all other colors. I just replaced the black ink cartridge and it still won't print black. Do you know the fix for this?


If you print primarily black, your black/yellow printhead may have worn out and needs to be replaced. Go to start, printers and faxes, select the L7680 and then select properties. Print a test page and run the troubleshooter to clean the nozzles and lines. If it's not the nozzles or lines, search for C9381A on google and purchase a new printhead it should be about $70.

Can't get the black ink cartridge to print


Try taking out the cartridge and inserting it again to make sure it was originally put in the printer correctly and not forced in.

Standard black printing has faded to grey.


Could just be a faulty cartridge?

My hp printer developed a similar fault, and despite all my attempts to clean, realign, whatever, the problem wasn't solved till I fitted a new ink cartridge. It's worth a try.
