Restoring Factory Defaults

Restoring factory defaults returns the printer settings to the original
factory settings.
Perform the following steps to invoke factory defaults:
1. Turn the printer power off.
2. Open the top cover.
3. Turn the printer power on. The printer starts POST.
4. The operator panel Error LED comes on solid.
5. Press and hold the operator panel button until all the LEDs are
on solid indicating the printer is restoring factory defaults.
6. Release the button. The printer indicates the operation is
complete by turning all the LEDs off except the Error LED.
7. The configuration mode can be selected by doing a brief button
press or closing the top cover which causes the printer to enter
either the normal mode or the demo mode.
