You can initialize the printer settings.

 When using the printer over wireless LAN, note that initialization erases all network settings on the printer, and printing operation from a computer over network may become impossible. To use the printer over network, perform setup with the Setup CD or perform it with the files on our website.

To initialize the printer settings, press and hold the RESUME/CANCEL button, then release the button when the POWER lamp flashes white 15 times.

All the printer settings are initialized.

 You cannot initialize the current position of the print head.
