Hi @Freeambler,
I'd like to help!
I understand you are receiving an E9 error.
An E9 error occurs when a problem occurs during a printer firmware update.
-
Set up the wireless setup again.
For more information, go to Wireless Printer Setup.
-
Touch the Information button
.
If the information page prints, the printer is back to normal state.
If the printer fails to print the Information page, it is still in recovery mode and needs to download the firmware again.
NOTE:
During recovery mode, the printer automatically downloads firmware from the cloud. Leave the printer about 2 hours, depending on your network speed, to complete firmware download and update.
Hope this helps! Keep me posted.
