Abstract

A print head recapping mechanism is disclosed for recapping a page width ink jetting print head structure, comprising a first stationary ferrous arm; a solenoid coil wrapped around a portion of the ferrous arm; a second moveable arm located substantially adjacent the first arm and biased towards the print head structure; a series of membranes attached to the second moveable arm the membranes sealing the print head structure when in a rest position; the solenoid being activated to cause the moveable arm to move away from the surface of the print head structure sufficient to allow a 'paper or film' to be inserted between the membranes and the print head structure for the printing of ink thereon. Preferably, the membranes are resiliently collapsible against the surface of the print head structure. The membranes can comprise two mutually opposed elastomer strips running substantially the length of the ink jetting portions of the print head structure so as to surround the ink jetting portions. The solenoid can include an elongated winding of a current carrying wire which is wrapped around a protruding portion of the first arm, the elongation being substantially the length of the print head structure.
