COMBINED CAPPER AND PLATEN FOR A STATIONARY PRINT HEAD

1 . A capper-platen for a stationary print head, the capper-platen comprising:

a platen arranged below the stationary print head, the platen being movable towards and away from the print head;

a capper having a perimeter gasket, the perimeter gasket being arranged around the platen and movable towards and away from the print head, the movement of the capper being co-axial to movement of the platen and independent from the movement of the platen, the perimeter gasket sealing the stationary print head when moved against the stationary print head; and

an actuator for selectively moving the capper and the platen towards and away from the print head.

2 . A capper-platen as claimed in claim 1 , wherein the actuator comprises a drive means and a track arrangement movable by the drive means in a direction perpendicular to the movement of the platen and the capper, the track arrangement having cams or tracks corresponding to the capper and the platen, and the capper and the platen each having guides acting against the cam or track corresponding thereto, the cams or track translating the movement of the track arrangement into movement of the capper and the platen towards and away from the print head.

3 . A capper-platen as claimed in claim 2 , wherein the track arrangement is movable between at least three positions, the three positions corresponding three configurations of the platen and the capper, those configurations being:

the capper and the platen being spaced from the stationary print head;

the capper being proximal to the stationary print head and the platen being distant from the stationary print head; and

the platen being proximal to the stationary print head and the capper being distant from the stationary print head.
