Question about HP Officejet Pro L7680 All-In-One Printer
Now saying there is a problem with the printheads
Sometimes it's just a case of the printer throwing a wobbly...
Try turning the printer off, leaving it for a couple of minutes and then turning it back on again.
(Sometimes it locks up in "shutting down" mode requiring you to pull the power lead, waiting 5 and then plugging back in).
If this doesn't resolve it and your printheads are in warranty I'd phone HP for warranty replacements.

SOURCE: Changing the printhead
FYI: The L7590 doesn't have any tape on either the cartridge or the printhead.
Right couple of things here...
1. The printheads in the L7590 are either K/Y (black/yellow) or C/M (cyan/magenta)... There's no single black printhead unless of course this is not an L7590 we're discussing here.
2. The cartridges ARE individual with K, Y M C (Black, Yellow, Magenta and Cyan).
It's likely that the printer has one of the following faults.
If the problem is the latter then you need to get the printer serviced and/or repaired at a service center.
If it's the former you should be able to fix it yourself.
If you're using non OEM (ie: not by HP) cartridges I'd recommend getting a new OEM/HP one to test before you go for a service as some cartridges are just poorly filled and/or designed.
Hope that helps.

To solve the
# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
# Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
# Continue doing this until it looks clean.
# Then dab the cartridge on the towel to make sure the ink is flowing.
# Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.
1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.
# Reinstall the cartridges, making sure you snap them correctly into the printer.
Hope this help. Please Rate My Response! Thanks!

Try this one
Take out the inks and printhead
Leave the cartridge door open, then unplug the power cord from the back of the printer while the access door is open
Close the cartridge door once the cord is unplugged
Reconnect the powercord, turn on the printer, then your printer will look for your printhead "Printhead missing or not installed correctly..."
Then put everything back. make sure it will snap in to place. Then print a calibration page, then scan it. This is just over writing the error message.
