ABSTRACT:
A print head restraint mechanism for limiting movement of a print head during transport of the printing apparatus is provided. The restraint mechanism includes a moveable pin that selectively engages the print head. An engaging mechanism moves the pin into and out of engagement with the print head when the print head is positioned in a restraint position. During printing the restraint mechanism is positioned away from the travel path of the print head to avoid interfering with print head motion. An interlock prevents actuation of the restraint mechanism when the print head is away from the restraint position.
