Question about HP Officejet Pro L7680 All-In-One Printer
Help my hp L7680 wont print black
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.

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.
