HP L7680 black ink prints a few yellow some not black, no Magneta or Cyan, but the cartridges are full

I have cleaned the print heads, all lined up. Clean the cartridge connections. Only use brand HP inks.

Help?

I'm happy that we got the results with the printhead to the cleaning operation. There is a manual method of cleaning of the printheads in this article:
http://support.HP.com/us-en/document/c01628836

This article is for a different question, but I recommend the manual steps to wipe the nozzles and contacts to make sure there is no jets dried or debris preventing the ink to produce quality printing results.

  • I can't go to my printer. It will not recognize the ink cartridges are full!

    My epson 7400 has not been used for 6 months. I cleaned and aligned the nozzles and it used 2 full cartridges. I installed new ink cartridges, and he says they are empty. Now none of the buttons work, it does not seem to recognize all commands. What should I do?

    Hello

    Turn the printer off

    Unplug the printer from the computer and the wall outlet

    Reinstall the cartridges

    Support all the ink cartridges until they snap into place to make sure that they are well housed

    Close the cartridge cover and push it down until it snaps

    Close the scanner

    Press on the Stop button to start loading of ink. It takes about 2 minutes.

    When the the light stops flashing and remains on, the ink load is complete

    Caution:

    Never turn off the Epson Stylus CX while ink is in charge or you'll be wasting ink.

    If the ink light flashes, press on the Stop button and lower all the cartridges safely

    Manually clean the print heads

    Plug the printer into the wall outlet and the computer.  Turn it on and try printing again.

  • My HP photosmart 6510e all-in-one scanning pictures in black and white but the docs are still in color.

    Scan pictures into my a6683w HP Vista in black and white, but the documents still scan in color.

    Hello there ingridt, welcome to the Forums!

    I noticed your post on the scans of your Photosmart 6510, scan to your system from Vista in black and white. I want to offer my suggestions to you to see if they can help you with this.

    First of all, try to launch the HP print and Scan Doctor who is used to fix the printing and scanning problems. You choose the option "Scanning" when the tool is run. It will inform you if the software is completely installed, or if there is a problem, it can not correct. If it detects an error and shows you a red 'X', I suggest then uninstall and reinstall.

    Here are some links to help with uninstalling and reinstalling if you happen to do these steps.

    1. uninstalling the printer software

    2. restart your PC

    3 reinstall: Photosmart HP 6510 e-All-in-One Printer - B211a

    Try a scan now and let me know how make you out!

    Good luck!

    2. You are able to print using the printer?
    3. What is the number and model of the printer?
    4. Did you the latest changes on the computer?

    Method 1

    Check and make sure that this printer is not set offline.

    (a) open the start menu and click on the "printers and faxes". This will open a window with a list of the printers currently installed on your computer.

    (b) double-click the icon of the printer that you want to change online. It will open a pop-up window describing all current print jobs.

    (c) go to "Printer" in the menu bar of the pop-up window and uncheck "Use printer offline." This action will change the printer from offline to online mode.

    Range of all-in-one printers, HP Photosmart 7510

    The function scan of my 7510 new does not recognize my computer as part of the network. (He said that the scanner can not find the computer)   It prints fine from the computer, however.  HP ran diagnostics and cannot find the problem in their system.  Suggested that I try to find a solution to the millisecond.  I was unable to find a solution yet.  Can anyone help?

    I suggest try to connect your printer to the computer and check if the scanner works.
  • I have a black screen after start up, but the mouse behaves normally. What's wrong?

    Hi, today I turned on my Pavilion DV9500t off for an hour. It would normally start Windows 7 64-bit (the Welcome screen was during more than usual), but instead of going to my office, the screen went black with the cursor has normally and only flashes do not. No keyboard function works well.

    I started from the install disc and from there I fixed start-up (no problem found) and restored to the previous points several times without success.

    There is no error message and I have not noticed a strange behaviour, with a view to this. Any suggestions as to the cause and the cure are greatly appreciated.

    I suggest you reboot your device and pressing F10 to enter the BIOS. While in the BIOS, I ran the disk hard self test in the diagnostics tab and see what the results are.
