resetting the printer to the factory default settings
Once the printer is configured for a network, its configuration settings are saved in its
memory.
Resetting the printer to its factory default settings will clear all the settings from the
printer's memory for your network. This should only be done as a last resort when
troubleshooting the printer.
Resetting the printer to its factory default settings may require you to reinstall the
printer software. Additionally, you will also have to reconfigure the printer's security
settings.
The printer's default settings are:
option default setting
communication mode Ad hoc
Network Name (SSID) [blank]
Encryption None
Wireless Radio On
Follow these steps to reset the printer to the factory default settings:
1. Verify that the printer is powered on.
2. Press and hold down the Power button.
3. While holding down the Power button, press the Cancel button six times.
4. Release the Power button.
