[tmdjs]

I amhaving the same problen.  After multiple tries, I cannot get my HP Envy 7640 to accept the 62XL ink cartridges as correctly installed. What do I do?  I have tried to reset my printer with no luck.  It will accept the empty one.

Greetings and Welcome to the HP Support Community. 

Don't worry, I'm here to help! To better assist you - Are you enrolled in the Instant Ink program? 

While you respond to that, let's try these steps -

1) Take out the cartridges. 
2) Unplug the power cord from the printer & wall. 
3) Wait for 30 seconds.  
4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector. 
5) Insert the cartridges back into the printer.

For the steps to clean the cartridges, refer to soluton# 3, 4 and 5 from this document.

Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware

Hope this helps!

Let me know how that goes.
