Officejet Pro L7650 black/yellow print head problem


There isn't a good fix for this problem. You can try the following;
1. Plug Unit Directly into wall, not thru a powerstrip.
2. Reset the Printer, Unplug Power Supply, Wait 30 Secs. Re-connect. Turn Power Back On.
3. Open Case, Wait for Printheads to move to right. Take Out Offending Printhead. Clean Gold Contacts / Soak Print Nozzles in 1/8" Water, if dried out. shake printhead to loosen stuck nozzles (watch out for flying ink!!). DO NOT PUT PRINTHEAD BACK IN YET!! Close Cover. Wait for printer to say "XXX Printhead is missing" Re-Open Cover, Wait till printheads move to right, Re-Insert Printhead, Close Cover. Reset if Necessary.
4. BTW None of this worked for me. I'm gonna see if anyone I know has one of these printers and swap out parts to see if it is indeed the printhead(s).
5. According to other posts, HP Service will tell you to try all of the above, then when it doesn't work, they tell you your printer is defective. Someone else mentioned a bad firmware problem. If you're out of warranty, your screwed. Another HP Horror Story! Oh My! California wants to elect their old CEO. lol.

Printhead Problem:


Have you tried to replace the black/yellow printhead? This is not the same as the ink cartridges, but it is located in the compartment under and to the right of the scanner lid.
Here is HP's link.

Getting message "problem with printhead k and y" what do I need to do to correct issue?


You need to replace the black/yellow printhead, and if you are using generic inks it won't last for more than a week. The new printhead is around $50.00

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.

Alignment failure


open the access door at the top of the printer

Remove the ink cartridges

Put your finger in the upper left corner of the printhead ( inside)

you will feel a small latch rigth there push it upward

the printhead will loose and you may now remove the printhead

L7680 won't print black


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.

HP officejet pro l7680 all in one


Most likely the print head has failed and the black is not printing which is causing the printer to have issues. Talk to HP as I guess printheads have warranty or simply change the yellow/black printhead. Or if all of these fail give the machine to HP to get you a new one as this is not right. I hope this helps.
