deskjet HP 720 printer

I have a problem that my 45 black ink cartige is full, but when I try to print the does'nt color black appear. I want to know if the Digital problem with connectors from the ink cartige or place it in the printer itself thank you

Try soaking the print head black in about 1 "of very hot water for 10 minutes, then gently dry the print head and try to print the test page.  If there is no black print pieces, even though the light and only a few strands, this would indicate the electronics is OK, but the cartrdige is at fault.  In this case a new cartridge #45 should solve the problem

If there is no trace of black most likely cause is the electronic and it would be not possible to fix the printer they are often used for $20 or less at thrift stores or garage sales.

  • Example: Deskjet 3050 - J610: printer removes items in the print queue

    Please see problem posted on June 9, 2016 and thread support. Sorry, I don't know how to go on this subject but the problem that I've marked as being solved is no longer is. It it is possible to mark as resolved and to reopen the thread please let me know how and I would be glade to do. Essentially sent items to the queue printing are deleted until they can print. They show in the print queue and then are marked "delete." I ran Print ahd doctor Scan of my desktop PC, and he says that everything is OK with the printer. I can see what the ink levels in the printer, and it printed on the printer succcessfully diagnostic information when asked to do so. I can see all of the information on the model of the printer, the serial number etc. so it seems that the PC can see the printer. But it will not print emails or Word documents - while he has done it before. Problem seems to have started when I tried to scan a document in and it would not. Printer is connected wireless and has an IP address, it doesn't seem to be the firewall attached - I disabled the Anti Virus software and it will not print. It runs the Windows firewall good that cause issues? I disabled that too, but it did not help. I followed the intstructions given by Gemini02 a HP Support Agent and it seemed to solve the problem but it only did it once and then continued to remove items from the print queue. I also tried to turn off the printer and then the PC, left for a while and then restarted them and that seemed to work. He already showed the printer as offline and printing and scanning doctor fixed that but when I ran it but still it only printed once and then returned to the deletion of items in the print queue. Grateful for any advice anyone can offer please.

  • Why my printer HP Deskjet 3350 A prints the message? Nothing to do with the scanning

    My HP Deskjet 3055 A printed satisfactorily for months. Recently transferred to a wi - fi connection and he began to Miss entire lines of text messages, it's printing.  Why would he do that?

    Hi Rosewright135,

    Thank you for being a member of the HP support community.  I understand that you have experienced problems with print quality because you changed printer Deskjet - 3055 has a Wi - Fi connection.

    I've included two different documents for you.  First a diagnosis of print quality issues is the document to follow when you have a print quality problem.  The information that you gave, I suspect that you have a print quality problem.

    I suspect that the transition to a wireless connection is probably a coincidence, but just in case I get the troubleshooting document printer does not maintain the wireless connection . Please follow the steps if the print quality paper does not solve the problem.

    HP Deskjet 970Cse only prints red after the new color cartridge installed. I use black HP 45 and HP 78 color. Both are new. I know the printer is an older model, but it works well a month ago.  Any help would be appreciated.

    Thank you for your help.  It was a faulty cartridge.  I pressed a white cloth on the ink source and only yellow and blue were visible, without red (magenta).  I've returned the fabric and cartridge in the store (with my receipt) and managed to get another canister... it worked!  Both cartridges have dates of expiry of 2016.  Glad I didn't have to spend time troubleshooting my printer.

  • HP Deskjet 1510 - Wont print in XP

    Hello

    I'm trying to set up a printer on an XP machine 1510. I tried again and again to get it going, but nothing works.

    In the current attempt, I installed base from the HP Web site drivers, the drivers are installed correctly and XP can see the printer, this is the default and I checked all the ports and parameters of the driver etc..

    However with everything apparently works, if you print a job goes into the print queue, is sitting there for a few seconds, then disappears, nothing prints not, nothing happens, the printer itself doesn't even make a noise.

    I tried the printer on my Win7 machine, works perfectly. I tested the USB ports and cable, no problem there.

    I have worked through many documents of troubleshooting on the 1510, including the spool of printer etc..

    I reinstalled the drivers and the software several times, the same result each time, see the printer XP is by default but when printing nothing happens.

    I'm getting closer to return the printer.

    Thank you

    Hi @JimDirt,

    Welcome to the Forums of HP Support!

    I see that your new printer HP DeskJet 2130 guard print a "test page" each time you print.  I'd be happy to help you and don't forget to come back to this thread and check "Accept as Solution", if I have successfully helped solve you the problem. If you want to say 'Thank you' to my effort to help, click on the "thumbs up" to give me a Kudos.

    I understand how frustrating, it would be for you. It seems that alignment has not completed when you installed the printer at the start. The alignment sheet must be scanned or the process repeats. This is normal and it will continue to realign itself ended successfully.

    This guide illustrates the alignment process:

    Load paper into the paper feeder (make sure that you load into the fresh, unused paper tray).

    Load plain, US letter or A4 paper in tray after installing ink cartridges.
  • DeskJet 3050 a: Deskjet 3050 a prints blur sometimes, new drivers, alignments, no cleaning, no joy.

    If I print a test page for the printer it comes out perfect.

    If I print a test page for Windows7 it comes out perfect.

    If I right click and highlight text when it is on the internet and press print it comes out blurry.

    Print an e-mail comes out blurry, even as wordpad.

    Basically, but no test pages come out blurry, unless I do a google search and find a random test page not associated with Win7 or HP which will be blurred.

    I tried new drivers, ink cartridges are fairly new, but they were good job and forwards the problem.

    I did several cleanings, alignments, not troubleshooting, no joy.

    He has been connected to the same USB port, worked many years.

    No updates of windows 7 or changes.

    No matter whether this printer is default, I also have a Canon iP2600 and it works perfectly, it was also in the years of system, once again no change, I can't see that would not cause this problem.  There is probably a change, but it is over my head as to what.

    Thank you

If you want to say 'Thank you' to my effort to help, click on the "thumbs up" to give me a Kudos.

    I understand how frustrating, it would be for you. You mentioned that you uninstall and reinstall the HP software. Looks like the drivers are corrupt, it is necessary to clean your system and try to reinstall again.

    Is the Canon iP2600 that printer as plugged in USB?

    You say that ' no updates Windows 7 or changes ", you have automatic updates is turned off? Please make sure that your Windows updates are up-to-date.

    When you install a USB printer, it is recommended that you disconnect the other USB printers during installation. In this way, the computer does not confuse the two and installs the correct driver.

    You unplug the Canon before reinstalling the HP Deskjet printer?

    I suggest to try the following steps in the following order for best results.

    If the problem persists, I will try this solution.

  • HP Deskjet 2540: Wireless printing problems with HP Deskjet 2540

    Hi all

    I have a problem with a printer HP Deskjet 2540 - it prints if I connected a USB cable; However, he refuses to print if I try to print wireless.

    I had initially solved this problem when I went into system preferences > printers and Scanners and noticed two 2540 Deskjet series icons in a window titled 'Printers '. I ended up removing one of these icons and set it as a default, which temporarily seems to solve my problem. Now, I see two icons back in the "Printers" menu and my printer refuses to print over my wireless connection.

    My printer is connected to my internet connection so I don't think there is a problem here - I also recently installed the software for this printer to make sure it wasn't some kind of driver issue; However, it doesn't give me the permanent solution, that I'm looking.

    Any advice? My operating system is OS X Version 10.9.5

    Hey @love2dance,

    Please come back to me and let me know what you have tried.  I found an article by HP which has a more in-depth approach to troubleshooting your network configuration.  Click on the title of the article and start of Solution 2 and work your way down until finish you setting up your printer successfully:

    Note that the steps are for Mac OS X 10.8 but you will find that again, as they apply to your configuration of Mavericks.
