OfficeJet Pro K850 - ink cartridge does not print

My K850 printer is not printing cyan. According to the Toolbox of the K850, cartridge series cyan was 75%, and the health of the print head has been fair. The cyan cartridge was beyond its expiration date I replaced it. The new cartridge does not better than the old cartridge print. Before I spend another $40.00 + did someone has something to suggest?


Although the cleaning of the print head has helped a little, it did not help, so I bought a new cyan print head. When I installed the new print head, the printer automatically aligned to the printhead and now cyan works very well. Unfortunately, the alignment process pointed out flaws in magenta and Yellow Printhead. Now everytime that I print anything the printer goes through a continuous systematic alignment printhead to try to correct the magenta and Yellow Printhead, waste of paper and ink, until I cancel all print jobs. New cleaning of the printheads and the contacts did not help. In the end, no matter what is the status of print head in the tool box, replacing the print heads is the only solution that worked.

    HP Officejet Pro 8500 a Premium does not print the docs of the computer, but will display a test page.  I constantly get a message that the computer cannot communicate with the printer.   Not only it will be not be printed docs, it will not print web pages using 11 IE or Google Chrome.

    I used print and Scan of doctor, he always reports there are no questions and print page one same test so I can not print anything else.

    Whenever I want to print, I have to restart the computer.  After the reboot, I have a chance to print.   This problem started on February 15, 2015.

    My operating system is Windows 8.1.   I have unintalled HP, rebooted, and then reinstalled the software software:

    The desk top is installed with a network card Netgear, I don't know the model, but I had it tested by a PC technology to verify that the card works.   The card and 8.1 of Windows have been installed on January 3, 2015.

    I have run virus scans and analyzes malware.  Whenever they show that there are no problems with my desktop computer.  What kind of desktop? Specially designed for my listing of... without brand computer parts store.  ASUS motherboard P6X580 Premium.  Now I will probably get hacked!

    I'm at my wits end.  And it's frustrating when I need to print something and the system hangs.  I often use screen printing to a word document to save in order to restart... but then I lose all sorts of features when I pick up what I needed.  It is also a time consuming.

    This printer we served well for two years and I have expensive cartridges pending; another two cycles of recharge.


    Addendum: can I scan with the HP printer help.  I open the HP printer assistant, he "gets" the printer information, then I select "scan a document or photo" and the printer answers.   I have no problem with the sweep.

    It has been awhile, but I played on something you wrote.  "There could be a software conflict with the HP software" everything worked very well... impression was shifted at best; just didn't know if it would work.  So I would eliminate a program, reboot clean, try to print, and then reinstall the software.  I finally found the culprit.  I had a program running in the background, occasionally.  When it ran, HP does not print.  Stop the program and I was able to print... Do not have a problem since I found it... I do not say that it was a software to share files... so I replaced since this program with something else that doesn't cause problems...  It took a long time and I couldn't work the question every day.... but I can say that I have problems printing for the past 5 days!  I can print with confidence.

  • HP Officejet 6500 a Plus: black ink cartridge does not print

    I have a HP Officejet 6500 a and have an operating system of Windows 10 on a Dell Inspiron 15R.  The printer does not print any black ink. I have genuine HP cartridges and the black cartridge is about 75% full. It was working properly until this morning. I downloaded your troubleshooting and everything seems fine. I ran the program cleaning head several times, but I can't always get black ink on a page. The other colors are fine. After the second head cleaning, I got a very small black image, but head cleaning has resulted in no black ink. I made sure that the wind had been reached on the cartridge and this problem occurs with wireless and hard wired connections. Time before, it happened and when I replaced the cartridge, it worked. After reading some of the messages on the map, it seems not to be the solution. I also hesitate to throw a cartridge that is only 25% used. Can you help me?

  • Photosmart 7510 - black ink cartridge does not print

    Recently, I replaced the ink cartridges on my Photosmart 7510 C311A. These are all the "genuine HP cartridges ', full.

    Black ink (with the symbol of the Pentagon) does not print, not at all. I ran through the standard troubleshooting steps:

    Cleaning of printheads

    Cleaning of copper contacts

    * Check for a good evacuation

    My colleague in the corridor as the printer even so I borrowed his black ink cartridge and tried: same problem. The printer does not record that there is a problem, but when I run printing tests, where there should be a black ink, there is absolutely none. All other colors print correctly.

    The printer doesn't lack NOT of the printer "align" test however does not offer a suggestion of what to do from there. I've not seen - in test reports - an indiciation of the misalignment.

    Suggestions on what to do now?

    I had the same problem. I had replaced the empty cartridge black and suddenly, no ink. Finally, what has worked is
    (1) I removed all the cartridges and cleaned the copper connectors with wet Publix.
    (2) I got a wet paper towel and he pressed repeatedly on the silver circular vent that would be under the black cartridge. I did until no black came. Let it dry.
    (3) I replaced all the cartridges and on the printer. I went to tools/clean the cartridge. I did it a couple of times and he finally printed black ink! I confirmed by going to tools/align, and align the cartridges successfully. He had kept before crashes when the black ink did not work.

  • HP OfficeJet Pro 8500 has: HP8500A does not print the programs in Microsoft office in color

    I don't really know when this problem started, as I often do not print Microsoft Office files on this printer, but today I tried to print things in 2013 of Microsoft Office.  Even if the grayscale setting has been disabled - they always printed on this printer in grayscale.  I tried to print on two of my other printers and they printed color very well with similar settings for these printers.  I tried to print my email address on the 8500 - it printed color very well.  I tried to print photos with photo gallery and my 8500 them printed in color as well, so it doesn't seem to be a problem with one of the cartridges in the printer color such that it will print color with other applications.

    I restarted my HP8500A, and I got the same results.  I restarted my computer, the same results.  I went ahead, downloaded and installed Microsoft Update Office 2016 think there must be a problem somewhere.  It made no difference.  When I print to the 8500 with shades of gray turned off in Word and print selected in Publisher - RGB I'm still printing in grayscale.  I take the same documents and I print on my other printers (HP Photomart C5580 All in One) and HP Deskjet 1000 and the same Microsoft Office 2016 documents will be printed in colour on both printers.  I'm running out of ideas to try to correct the problem. Any ideas?

    Thanks for your reply.  After trying a few other things, I saw that page print test HP and the Scan doctor kept coming out in grayscale, but still the print quality diagnostics Page was in color and everything was reported as good.  I just decided when all else fails, uninstall the printer driver and then reinstalled as it was the last thing to reset.  I have restarted everything, kept my fingers crossed and all print in perfect color!  For now at least!  So, I would say that my problem is solved and if it happens again, I'll uninstall and reinstall to try to resolve that obviously some sort of glitch mounted in the driver software.

  • OfficeJet Pro 8500 a910 a does not print

    Hey all,.

    had some problems recently with my a910 Officejet Pro 8500 has.

    From 1 day to the other, it stopped printing, each document is put in the waiting room, but no paper out.

    The vacuum-ing line made no difference, al checked settings in the box.

    Had removed all software, installed again, all via HP.

    All fine until testpage, no go.

    All 3 Doctoringtools of HP given their chance, all very well once again, until the testpage, so no reaction.

    I'm all of the options, maybe one of you, the specialists have everything?

    THX in advance and regards, Sander

    I don't know why, after you close a couple of times b4 electricity, to reset, no result then.

    Maybe now, with the new software (6th time install) and HP tools, he decided to once again where I bought it for...

    Thus, solved!

  • 3520 Deskject HP all-in-one: newly replaced black ink cartridge does not print

    My ink level is full.  I just replaced my black cartridge (with genuine HP cartridges). No black is printing.  I tried all the troubleshooting tips including the alignment of the printer, clean the print head. Remove and reinsert the cartridges.  I replaced the cartridge several times during the past year is nothing new.  Can't understand why black will not only be printed.

    This is your last hope.

    Watch the videos and if you can remove the printhead and clean, it might work.

    Let us know...

  • HP 78 and purchased red ink cartridge does not print, purchase was by mail with a HP 45 cartridge

    Purchase was about a month to six weeks - waiting for the old cartridge to run out. Where red is normally printed is a shade of light green. Open to a suggestion of how to fix this problem. The printer is my old reliable Deskjet 990Cxi. The system is a HP Tower. works with Windows 7 SP2. This result occurs when the test page is printed when you install a new cardtrige (s) and when I print a document using Word with red symbology. There is no error message, just the eye ball and see that the page is incorrect. I bought HP cardtriges four or five times before with no problem, as long as they are not available in retail stores more.

    Thank you very much, Bill [personal information deleted]

    Okay Bill, because it is still under warranty I would say certainly contact HP telephone support on this issue, because I think that you will need a replacement cartridge.

    Can you please let me know how you go?

    Thank you
