The print head will not move side to side just front to back

First, check to make sure nothing is inside the printer that could be interfering with the print head. Make sure that the switches (pictured below) in the back left and right of the print head are not being hit. If those are clear and you are still having problems you can try tightening the gear pulley to the right of the printer. If you are still having problems you can contact us at [e-mail].
