Reset the print server to factory default settings
I needed to factory reset a Brother HL 2270 printer, and found the following instructions:
1: Turn the printer off.
2: Close the front cover, make sure it is plugged into power.
3: Hold down the “Go” button and turn the printer on. Wait until all of the LEDs light up and the “Ready” LED turns off.
4: Release the button. Make sure the LEDs turn off.
5: Press the “Go” button six times. Make sure that all of the LEDs light up, indicating the printer has been reset. The printer will then reboot.
