ABSTRACT:
A printer is disclosed which has:(a) a pagewidth printhead assembly having a pagewidth printhead and a plurality of nozzles located along the printhead for delivering ink onto print media as it is transported past the printhead, and(b) a capping/purging mechanism associated with the printhead.The capping/purging mechanism comprises—(i) a rotatable turret having a longitudinal length corresponding substantially to that of the printhead,(ii) a longitudinally extending capping member carried by the turret,(iii) a purging chamber carried by the turret and connected in fluid passage communication with a suction device,(iv) a first actuating mechanism arranged to effect rotation of the turret selectively to position the capping member or the purging chamber in alignment with the nozzles of the at least one printhead, and(v) a second actuating mechanism arranged to effect movement of the turret whereby an aligned one of the capping member and the purging chamber is selectively positioned in engagement with the printhead.
