Printer display flashing

HP Recommended
HP Envy 7640
Microsoft Windows 7 (64-bit)

After my Envy 7640 printer is plugged in for several hours, I notice the display is flashing and has a message similar to 'there was an error in the connection and you need to turn the printer off and back on again'. It doesn't respond to pressing the on/off button, I have to physically unplug it and plug it in again after 10 or more seconds to get a normal display again. Sometimes the display is frozen even after this and doesn't respond to touch so I have to unplug it for a longer period of time before plugging it back in again. 

 

I started plugging the printer directly into the wall outlet instead of a power strip when this started happening but it didn't resolve the problem. Any suggestions?

@cybergrrl

 

Welcome to the HP Support Community.

 

Let's try and do a firmware update: https://support.hp.com/in-en/document/c02919168

 

Are you able to remove the cartridges from the Printer? If yes, remove them and unplug the Printer and plug it back a

in and insert the cartridges.

 

Let me know if this helps.

I'm sorry I was not able to get back to you until now. I tried doing a firmware update but it said it was already updated. I tried the removing and re-inserting the cartridges as you said and so far, no problems, but I'll have to wait a few days to be sure. 

BTW - I have not been able to successfully install the last 2 updates from HP -

 

HP - Printer - 6/9/2016 12:00:00 AM - 17.59.0.6180

Installation date: ‎1/‎8/‎2018 9:14 PM

Installation status: Failed

Error details: Code 80070103

- AND -

Hewlett-Packard - USB - 2/18/2019 12:00:00 AM - 40.13.1167.1948

Installation date: ‎3/‎29/‎2019 12:10 AM

Installation status: Failed

Error details: Code 800F020B

 

but since they were both optional, I wasn't that concerned.

I'll let you know at the end of the week if it loses power again or if it appears to be resolved. Thanks.
