sounds like a connection issue with wiring/ ie wrong cable to socket/ plugged in backwards etc..Right i turned my printer on for the first time and the printer head shot across to the left and there was a loud grinding noise! which was coming from the left hand side of the frame. Its coming from the belt that drives the printer head, like if theres gears jumpinf or grinding. can anyone offer any help??
this is the most frequent reason for the run away carriage.. double check all your wiring/connections..
