This printer has an automatic interface selection feature that is turned on by default. This lets it automatically change the interface to USB, or Ethernet depending on which interface is receiving data.

Since the default setting is on for the automatic interface selection mode, simply connect the interface cable to the printer. Always turn off both your computer and printer when connecting or disconnecting the cable.

Auto Interface selection can take a few seconds to work. If you only use one interface it would be advisable to select that interface; use the control panel to access the General Setup menu, choose Interface and then choose Select. If only one interface is chosen, the printer will allocate the entire input buffer to that interface.
