Turn the printer OFF by pressing and holding the START/STOP button until the POWER LED turns orange/amber.
Move the printhead all the way to the left or to the home position.
Using a blunt-pointed object (a ballpoint pen cover, for example), gently press and hold the button located in a small opening just above the printer's Ethernet port. Click here to see its location.
Turn ON the printer by tapping START/STOP button once while still pressing and holding the network button.
Release the network button once printhead initializes or after the printhead moves back and forth from the home position.
