Ink cartrige remove and reinstall error

[Kbchiampa]

I have an HP 7640 printer with instant ink. The printer keeps telling me to remove and reinstall the ink cartridges.  Everytime I do this I get the same error message. This has been going on for a few weeks now.  Please help

Hi @Kbchiampa,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand you have trouble using the ink cartridges with the Instant Ink enrolled HP ENVY 7640 e-All-in-One Printer, 

Have you checked your HP Instant Ink account page? Your Instant Ink account page will have notifications if there are any issues with the account or recent cartridge shipment, and it will even provide solutions on how to fix the issue. You may log in to your HP Instant Ink account page from here.

Also, please try the steps below and let me know if this helps.

Please remove the Cartridges from the Printer if possible, and try a Hard Reset. Do keep us posted to help you better

** Hard reset :
1. Turn the printer on, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Unplug the power cord from the wall outlet.
5. Wait at least 60 seconds.
6. Plug the power cord back into the wall outlet.
NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
7. Reconnect the power cord to the rear of the printer.
8. Turn on the printer, if it does not automatically turn on. The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
9. Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Please uninstall the HP Smart app --> restart the Device, Wi-Fi router and printer --> install it back and add the printer

Please update the Firmware from the link, This will help with how to update the firmware on the printer or devices

I hope this helps.

Take care and have a good day.
