Hi,

Unfortunately it's highly likely that your black printhead is clogged due to the conditions you are using the printer in (ie: warm, dry, air-conditioned?).

I get this a lot in hot offices and school classrooms.

The only solution I've found that works long term is to use a dyebase black ink instead of the pigment ink that HP provide but this obviously means you would have to source a 3rd party ink supplier with ink of this type.

In the mean time a shorter term solution is to purchase a new black/yellow printhead and follow the process for changing the printhead for this new one.

Hope that helps.

Martin

SOURCE: HP L7680 prints red instead of black

Check your default ink setting if red is default then change it and make black ink default settings.
Thank You

SOURCE: HP L7680 black print streeks every 5-6 lines

Any inkjet printer with this problem is caused by a build-up of ink on the undercarriage or the wiper assmbly.Usually on the right side where the cartridges are at rest. You have to get messy and clean that build-up with moistened cloth, qtips etc.

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.

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.

HP L7680 won't print black, cartridge is new, says it is full, Self diagnostic page says printhead is good


Try printing a Diagnostic page or clean cartridge. Looks like the printheads might be clogged due to low usage or general wear and tear, they may not be working as desired.
