    摘要： A printhead maintenance station (20) for maintaining a printhead (5) in an operable condition is provided. The maintenance station (20) comprises an elastically deformable pad (6) having a contact surface (7) for sealing engagement with an ink ejection face (8) of the printhead (5). The maintenance station (20) also comprises engagement mechanism (25) for moving the pad (6) between a first position in which the contact surface (7) is sealingly engaged with the face (8), and a second position in which the contact surface (7) is disengaged from the fac (8). The maintenance station (20) is configured such that the contact surface (7) is progressively contacted with the face (8) during sealing engagement and peeled away from the face (8) during disengagement.

    摘要： There is disclosed an ink jet printhead which comprises a plurality of nozzles (3) and one or more heater elements (10) corresponding to each nozzle. Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble (12) therein. The generation of the bubble causes the ejection of a drop (16) of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. Each heater element is configured such that the energy applied to it to heat the bubble forming liquid to cause the ejection of a drop is less than that required to heat a volume of the ejectable liquid equal to the volume of such a drop, from an ambient temperature (being the temperature at which the bubble forming liquid enters the printhead) to the temperature of such a drop when it is ejected. The printhead thus has a self-cooling function.

    摘要： A capping mechanism (21) for a printhead having a capping member (29) which has a length corresponding substantially to the length of the printhead and which is configured to contact the printhead in nozzle capping engagement, and a pivotal carrier (30) supporting the capping member. An actuating mechanism (31) is provided and arranged to effect pivotal movement of the carrier back and forth between a first position at which the capping member is located remotely with respect to the printhead and a second position at which the capping member is located in contact with the printhead. The capping member is pivotally mounted to the carrier and is arranged to pivot relative to the carrier during back and forth transitional movement of the carrier between a transition position and the second position, wherein the transition position is located intermediate the first and second position.
