How do I fix D80774EC error on HP ENVY 7855 printer?

[windyHoffman]

The printer screen shows D80774EC on blue.  Restarting lets the printer operate for a while, but then overnight the message comes up again.

I have unplugged, waited, and powered up again.  Still get message after printer works for a few hours.

Reinstalled ink cartridges.  Same effect.

So what do I do?   It is annoying to restart every day when I need to use the printer or scanner.

Hi @windyHoffman,

Welcome to the HP Support Community. 

I'd be happy to help you! 

I understand you are receiving a "D80774EC" error.

We can perform factory defaults on the printer to resolve the issue but you will have to set up the printer and the service again.

• The reset instructions are specific for your printer and performing those steps on a different printer may corrupt the device.
• I've sent you a private message with reset instructions, follow the reset instructions to perform a full reset and re-initialize the printer.
• In order to access your private messages, click the private message icon on the upper right corner of your HP Support Community profile, next to your profile Name or simply click on this link: https://h30434.www3.hp.com/t5/notes/privatenotespage
