Inkjet print head recapping mechanism
First Claim
1. A print head recapping mechanism for recapping a page width print head structure, the recappino mechanism comprising;
- a first, stationary ferrous arm;
a solenoid coil wound around a portion of said ferrous arm;
a second, moveable arm juxtaposed with said first arm and biased towards said print head structure, the moveable arm being displaceable between a first, rest position and a second position; and
a sealing means attached to said second, moveable arm, said sealing means sealing said print head structure when said moveable arm is in its rest position, said solenoid being activated to cause said moveable arm to move to its second position away from a surface of said print head structure with sufficient clearance to allow print media to be inserted between said sealing means and said print head structure for the printing of ink on said print media, a magnitude of current required to displace the moveable arm from its first position to its second position being greater than a magnitude of current required to retain the moveable arm at its second position.

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.

7. A method of operating a hand held camera device having a printhead for printing on a roll of print media, said print head including a recapping mechanism and a paper cutting mechanism, the method comprising the steps of:
-
activating said recapping mechanism to move said mechanism away from said printhead so as to allow for printing by said printhead on print media;
printing an image on said print media;
cutting said print media on a border of said image so as to form a detachable separate image;
rewinding said roll print media so that said print media clears the space between said printhead and said recapping mechanism; and
deactivating said recapping mechanism so that it moves adjacent said printhead.
