摘要:
A method of maintaining a printhead in an operable condition is provided in which a pad is moved between a first position in which the pad is sealingly engaged with the printhead, a second position in which the pad is disengaged from the printhead and a third position in which the pad is engaged with a pad cleaner. The pad is biased towards the second position relative to the third position.

A printhead maintenance system comprises: a stationary pagewidth printhead having an ink ejection face; an elastically deformable roller having a contact surface for contacting the ink ejection face; and a mechanism for rolling the roller across the face. In use, the printhead remains stationary when the roller is rolled across the face.
摘要:
A printhead maintenance station for maintaining a printhead in an operable condition. The maintenance station has an elastically deformable pad coextensive with the printhead. The pad is a one-piece elastomer pad having a uniform contact surface configured for sealing contact with all nozzles in an ink ejection face of the printhead. A mechanism is configured for reciprocally moving the pad between a first position in which the contact surface is sealingly contacted with all nozzles in the ink ejection face, and a second position in which the contact surface is disengaged from the face. The pad and the mechanism cooperate such that the contact surface is progressively contacted with the face during sealing engagement and peeled away from the face during peeling disengagement.

A printhead maintenance station for maintaining a printhead in an operable condition is provided. The maintenance station comprises an elastically deformable roller having a contact surface for contacting an ink ejection face of the printhead, and a mechanism for rolling the roller across the face. The contact surface of the roller is configured so as to avoid trapping of ink on or in the roller surface.

A printhead maintenance station for maintaining a printhead in an operable condition. The maintenance station comprises an elastically deformable pad having a contact surface for sealing contact with nozzles in an ink ejection face of the printhead. The contact surface has a sloping profile. The maintenance station has a motor and cam arrangement for moving the pad substantially perpendicularly with respect to the ink ejection face. The pad moves from a first position in which the contact surface is sealingly contacted with the nozzles to a second position in which the contact surface is disengaged from the face. The movement and the sloping profile of the pad causes the contact surface to be peeled away from the face during disengagement.
摘要:
Provided is a printhead assembly that includes a support structure with a printhead mounted on the support structure, said printhead having an ink ejection face, and a print media guide proximate the support structure for guiding print media past the printhead for printing. Also included is a wicking element mounted on the support structure between the support structure and the print media guide, as well as a printhead maintenance station configured to facilitate the transferral of ink from the printhead to the wicking element.

A method of maintaining a printhead in an operable condition is provided. The method comprises the steps of: (a) providing an elastically deformable pad having a contact surface for sealing engagement with an ink ejection face of the printhead; and (b) moving the pad between a first position in which the contact surface is sealingly engaged with the face, a second position in which the contact surface is disengaged from the face, and a third position in which the contact surface is engaged with a pad cleaner.
摘要:
A method of sealing nozzles on an ink ejection face of a printhead is provided. The method comprises the steps of: (a) providing an elastically deformable pad having a contact surface for sealing engagement with the ink ejection face; and (b) moving the pad from a second position in which the contact surface is disengaged from the face to a first position in which the contact surface is sealingly engaged with the face. The movement causes the contact surface to be progressively contacted with the face during sealing engagement.

The movement causes a contact angle hysteresis such that ink is wicked from the printhead onto the contact surface during disengagement, but remains substantially in or on the printhead during engagement.

Provided is a printhead assembly including a support structure, and a printhead mounted on the support structure, said printhead having an ink ejection face. The assembly also includes a print media guide proximate the support structure for guiding print media past the printhead for printing, and a wicking element mounted on the support structure between the support structure and the print media guide. Further included is a pad with an angled contact surface to operatively facilitate the transferral of ink from the printhead to the wicking element.
