[bullet12]

Unable to copy or scan because I am unable to change the paper size from 6 ¾" envelope to standard plain paper 8 ½ x 11.

Check the scanner bar functionality: partially lift the scanner lid, and then press the Copy button or icon. If the scanner light does not illuminate or move across the glass then it should be a scanner issue.

Perform a power reset , Reset the printer to recover from printer errors or failures.

1. Turn on the printer, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Wait at least 30 seconds.
5. Plug back the power cable straight to a wall outlet and printer without any surge protector.
6. Turn on the printer.

Update the printer firmware to install the latest updates
