Photo Tray Blocked Error

[sander47]

Hi, 

I have a HP Envy 7640 Printer, I changed the ink today, and now every time I try and print something it comes up with the error "Photo Tray Blocked". - I can assure you it is not blocked. I followed the guidelines online for this error and everything is in order, yet it still won't print.

I might cry! I just bought the very expensive ink today to put in, and now it doesn't want to print anything. My warranty expired so I can't speak to anyone over the phone, and the virtual assistant brings me to the same guideline I followed, but did not work.

 I restored the printer, turned it off and on again - noting is working. I need to print my work!!!!

PLEASE HELP!

Hi @sander47

Welcome to the HP Support Community. 

Appreciate you trying the steps, let's try resetting the printer - 

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. 

Have you tried re-seating the tray? If you haven't, try step#1 from this document. 

Also, try updating the printer's firmware. Download and install the firmware for macOS 10.12 version from this link. 

Note - The firmware update is specific to HP ENVY 7640 e-All-in-One Printer series. 

Hope this helps! Keep me posted.
