Closure mechanism for a printhead
First Claim
1. A capping mechanism for a print engine, the capping mechanism including:
- A closure for a printhead of the print engine, the closure being displaceale between a closure for a printhead of the print engine, the closure being displaceable between a capped position in which the printhead is capped and an uncapped position in which the printhead is uncapped;
a resilient member which acts on the closure for displacing the closure; and
a displaceable body which co-operates with said resilient member such that, when the body is in a parked position, the body engages the resilient member and urges the closure toward the capped position and, when the body is out of its parked position, the closure is urged by the resilient member to the uncapped position.

Abstract
A capping mechanism for a print engine includes a capping member mountable in alignment with a printhead of the print engine. The capping member is displaceable into and out of abutment with the printhead for capping and uncapping the printhead respectively. A torsion bar arrangement acts on the capping member for displacing the capping member. A mechanical displaceable element co-operates with the torsion bar arrangement such that, when the element is in a parked position, the element engages the torsion bar arrangement to cause the capping member to be displaced into abutment with the printhead to cap the printhead. When the displaceable element is out of its parked position, the capping member is urged by the torsion bar arrangement out of abutment with the printhead.
