  • jcleary Aug 20, 2008

    Tried the HP Support yesterday. They are telling me it is a malfunction and I have to buy a new printer! Of course it is just our of warranty!

  • jcleary Aug 20, 2008

    Spoke with HP support again. They said I am out of luck and will have to buy a new printer. I said it will not be an HP!

  • morrisrsm Sep 03, 2008

    I have exactly the same problem only my printhead reported to be defective is the cyan/magenta.



  • gettsold Jan 15, 2009

    have just replace the black/yellow printer head with an HP printer head and the printer does not recognize the new printer head. It keeps saying replace printer head black/yellow.
    Tim 703-298-7218 call anytime.

    I also have the error message 'Printhead(s) Problem', but mine is the magenta/cyan printhead. I called HP technical support - was on hold for 15 minutes before I talked to anyone. She put me on hold for 7 minutes and then said she was transferring me to technical support and gave me a case number. I was on hold for technical support and then got disconnected. I called back and have been on hold for 17 minutes. While I have been on hold, I went to the web site and followed the instructions - but no luck. I have also turned the machine off, disconnected the power cord, reconnected the power code and turned the machine back on. I am still getting the same message. This would almost be funny if I didn't need to get my work out!!!!!!

    This is my second HP Officejet Pro L7680 printer.
    The first one (brand new) said it had a problem with both printheads immediately after installation. Couldn't solve it so we sent it back to the supplier. I have just received a new one which is reporting the same error on the Black/Yellow printhead and I haven't even got through installing it fully yet!
    Nothing I do makes a difference and I am now faced with sending back a second BRAND NEW printer!
    Aaaaaaaaaaaaaaaaaaaargh!

    My Officejet Pro L7680 was replaced with a "refurbished" printer rather than a new printer 9 months after purchase...(they, as in HP and Staples, give impression unit will be replaced with new one if u purchase "Service Warrenty"; they fail to tell u warrenty expires when unit is replaced).

    18 months into owning such an expensive unit, printerhead (K/Y, Black/Yellow), began showing "Streaks", HP sent new printerhead, which worked perfectly....for 3 days.

    HP tech advised I need a new printer...

    After owning a total of six HP computers, desktops and laptops & 3 HP printers, (wish my G55xi had not died), this will definitely be my last HP printer.

    HP Corp. should be going online to read all the negatives with their printers and advise Tech Support to replace the units, however, I assume if they would do such a rightous act, they would need to contact Washington for a "bail-out".

    Nuf said.

When installing the print heads out of the box you MUST shake them for 30-60 seconds, same goes for ink tanks. If you do not then the lubricant that is added to them will seperate and it will draw thinned out ink causing damage to the print heads. Also, if your system sits for more than a couple weeks (and this goes for ALL printers) then run a test page ence every 2 weeks to keep the system from drying out.

I used to work at a couple office supply stores and this was almost always the issue with bad printheads on HP, Brother and Cannon printers.

You may have some luck with trying to following...
I have brought back to life a few printheads by putting them in a bowl so the spot where the ink comes out (the actual printhead) is on the bottom and the rest is standing up away from the chance of getting wet...
1st ) Add a few drops of rubbing alcohol to help soften the ink 2nd ) Fill with some hot water so it covers the print head area and let it stand for a few minutes 3rd ) Let it dry, shake it off, etc... I wouldn't suggesting touching the bottom with paper towel. 4th ) install and hope that it recognizes it without a problem...
5th ) if it still sees a problem you could try a reset.... power down, unplug, hold # and 6, plug in and power. Wait for message to come up - 15-45 seconds. If it shuts off press power and let it do it's thing

    I had a lot of problems after I bought and inserted refillable cartridges.

    I suspected that HP were accessing the printer via the internet and I blocked printer access to the web. After this I had no more problems!

    Also they used netbios, which is open to abuse by hackers - I blocked this protocol on the PC and the router.

please take your print head and get it tested or get it replaced, or you could take your printer to a local HP service centre and get it checked, rather than trying to fix it yourself you mite damage the sensors for the print head.

The error states that you are using non-HP cartridges for all colours. If black prints fine then you should replace the colour cartridges with genuine HP colour carts. You should be able to get a refund on the refills since they clearly do not work as intended.

L7680 has been printing perfectly - printed


Yes, you can pop the cover on the right over where the printhead parks, and remove the black/yellow printhead and soak it in about a 1/4 inch deep water for 30 mins or so, you only want the nozzle area on the bottom in the water. However if you are using generic inks it may report a printhead failure soon. After soaking you dab the bottom on a paper towel and look for a solid black line on the towel.

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.

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.
