Error in the printer - Deskjet 6840

My printer displays the message - "Not compatible with the printer ink cartridge" and will not print a document.

I use HP 94 and 95 cartridges. They were new a month ago. The printer has been my reliable MAC since the purchase of this issue four or five years ago.

What should I do to clear the message and continue printing?

Thank you

These new trucks never worked, or made the mistake of the printer on when you inserted the?  If the latter, one or several carts my be bad.

You can try to remove the two wagons and close the cover

Turn the printer off

Remove the power to the printer for a few minutes

Plug the print back, turn on.

Once he tells you that the carts are missing, insert 1 and close the lid.

Look for the error messages on this basket.  If it appears, and the error message on this basket, than using another basket if possible as it appears, it may be bad.  If there is none, pass the following, if it doesn't throw an error to try to printer.  If so, what this basket can be the problem.

    Hi @roopuk,

    Thanks for getting back to me.

    Sometimes the manual DNS 8.8.8.8 / 8.8.4.4 won't work in some configurations of network users.  Try the same steps as described above, but this time use the following parameters:

    Manual preferred DNS Server: 209.244.0.3
    Auxiliary manual DNS server: 209.244.0.4

    If you encounter the error, as before, we take our proverbial gloves off to try a more intensive troubleshooting.

    What is happening, it is that your router allows your printer connection that to enable wireless, but not a secondary connection to Web services.  In order to get these devices to 'shake hands' a second time, you may need to enable DMZ mode on your network through the router's built-in Web server.  HP does usually not this configuration for its customers as errors can cause serious network problems, but I can certainly post the info you need on your router or the ISP of the staff support company so that they could help you directly.

    Here is the information that you need for your provider service to open ports on your router/modem...

    -Multicast must be enabled
    -Hello enabled for AirPrint (relevant for iOS and Mac OS users)
    -Mac filtering should be disabled
    -Also, make sure that your router's firmware to date if
    necessary
    - The dmz on the router mode and turn it on to the printers IP address: _

    Ports to open are: Eprint and Apps

    Incoming Ports.

    UDP
    80
    443
    ------------------
    Outbound ports

    TCP
    5222
    5223
    -------------------
    Once they are open, you should have no problems connecting to services web eprint on your device.

    I would like to know how it works for you.

  • C4780 - error in the printing system

    C4780 worked without incident for months until recently - now I find randomly in status 'offline '.  Today has been visited by "error in the printing system.  Any ideas?  I already deleted the printer and the software which then does a re - install using the downloaded software from the HP site (can't locate the original install CD).

    OK, I'll assume that this printer is connected wireless to your router.  I would like to know if it's USB to your PC.

    First of all, don't use WEP.  It is not safe and can cause connection problems.  Use WPA with a password of 13 + character that you create yourself!  Much easier and safer.

    From the front of the printer: [Scan] Setup > network > wireless network Test.  It will be radio of the printer self-test.

    When the printer is offline, run this utility.  It will tell you what is happening.

    Good question.  Although it is listed as being supported under Snow Leopard, there is not another print and scan all drivers.

  • 'Use the cartridges SETUP' error on the printer, need help!

    I bought the printer last year in the months of August and after 6 months of use, it started having problems printing wireless. I always had to use USB to print from my laptop so I was recommended by people in this forum to reset my printer to the factory.

    I have reset several times and nothing worked, so I was advised to do so by using the Cancel button and the middle button that reset the printer. Now the problem is it says "Cartridges use SETUP" and my printer is out of warranty, it expired last month. I'm really confused about what to do. I am a student and I still have the print job and I can't afford a new printer. Calling support has no idea what to do and email support does not because of my warranty as you exhale.

    My printer is a HP Deskjet printer Wireless 3070. Product number is CQ191B.

    I really need help has begun the new year of college and I have a lot of missions to print.

  • HP P3015: ERROR ON THE PRINTER CAN'T USE. There 49.4C02 OF the ERROR AND DO WE ALLOW to ENTER IN THE MENU SETTINGS/AUTO

    OUR LASERJET P3015/CE527A CAME UP WITH THE ERROR 49.C02.  HE WILL NOT ENTER

    MENU/SETTINGS FOR AUTOMATIC RECOVERY.  IT COMES UP WITH THE ERROR AS SOON AS IT IS TURNED

    TURN IT BACK ON AND CANNOT ACCESS THE SETTING.

    This could be a few things-

    First thing I would do, is try to turn the machine off and then remove the network cable from the machine.  Once extracted, try to turn the machine on and see if the error goes away. If so, there are probably a print job corrupted in the queue. Which you can remove by going in Printers and devices - the print driver for the HP - go to 'see what's printing' - right click and delete the tasks in there. If the drivers are not on a server or on your computer, you may wander and find the computer on which the print job is
