Unknown Device error

I am getting this error on my printers screen

 

DISCONNECT MEMORY DEVICE FOR MORE INFORMATION SEE THE ELETRONIC USER GUIDE-ALSO CALLED HELP-AVAILABLE ON YOUR COMPUTER AFTER AFTER YOU INSTALL THE SOFTWARE.

 

There is no memory card attached or inserted in the printer. I have tried a hard reset with no success and I am unable access the touch screen because of the message.  I have downloaded the latest firmware, but when I run the HP Printer Update the status says Up-To-date.  However I am wary of this message because the firmware I downloaded has a date of October 2020 and I haven't updated any driver or firmware for this printer since at least March of this year unless there an autoupdate  happened without me knowing. 

 

I am actually able to print but have no access to the printers touch screen and so can't manage the printers functions on the printer.  The HP diagnostic tool I downloaded from the HP support site, HP Print & Scan Doctor 5.5, detects the printer and successfully prints a test page when I run it.

 

The printer worked fine and the last print job before this error was a print job which was sent to the printer via the printers email address.

 

I am at my wits end and need some help.

 

Regards,

Edinco

Welcome to the HP Support Community.

 

We'll have to perform a reset on the Printer for this. I have sent you a private message, for more details that cannot be shared in a public post.

 

Please do check your inbox on the forums page for the private message.

 

Let me know if this helps.

 

If the information I've provided was helpful, give us some reinforcement by clicking the Accepted Solution button, that'll help us and others see that we've got the answers!

 

Thanks!
