An improved ink-jet printhead cap is described. In its preferred embodiment, the cap has a sealing lip, which extends peripherally around the generally planar expanse of the cap, the lip being suspended by a horizontal, resiliently deflectable, elastomer span that is supported on either end by vertical supports that define a channel dimensioned to receive partway therein the annular boss of a cap mount mounted on a sled. In cross section, the lip is centered above the channel, protrudes upwardly...

A print head cap includes a bottom surface; and a ring-like lip. The ring-like lip surrounds the bottom surface, protrudes toward a nozzle surface of a print head of an ink jet printer and is elastically deformable. The ring-like lip is pressed onto the nozzle surface to cover the nozzle surface therewith. The ring-like lip has corners that change the direction surrounding the bottom surface. The corners of the ring-like lip are more elastically deformable than the other portions of the ring-lik...

There is disclosed an inkjet printer including: a printhead having a front surface in which is formed at least one nozzle row consisting of a plurality of nozzles from each of which a droplet of ink is ejected; a maintenance unit including a purge cap which receives ink from the nozzles during a purging operation, the purge cap having a contact surface to be brought into contact with the front surface of the printhead, and at least one main channel extending alongside the nozzle row; and a plura...

A printhead re-capping assembly for a printer having a chassis, a platen assembly and a pagewidth printhead operatively mounted on the chassis to carry out a printing operation on print media passing over the platen assembly includes a base structure that is mounted on the chassis. At least one static solenoid is mounted on the base structure and is connected to an electrical power supply of the printer. A support member is actuable by the solenoid to be movable with respect to the chassis betwe...

In a suction recovery method in a liquid jet recording apparatus in which the discharge port surface of a recording head is capped by a cap in response to the movement of a carriage carrying the recording head thereon and which is provided with an atmosphere release valve for introducing the atmosphere into the cap after or during the suction of ink from the discharge ports, provision is made of one or more rails disposed on the back of the cap in parallel to the direction of movement of the car...

A capillary vent system for a service station cap system in an ink-jet printer having a basin formed on a substantially planar surface mounted on the under side of a nylon sled subjacent a cap for a printhead mounted on the top surface of the sled which serves as a cover for the basin. A vent is defined between a semicircular groove formed on the under side of the basin cover such that the vent is in fluid communication with the basin and has a lower surface substantially coplanar with the under...

A maintenance device for shielding a print-head includes a casing having a first traveling path and a second traveling path transverse to the first traveling path, a sliding member disposed back and forth along the first traveling path; and a shielding unit including a seat movable back and forth along the second traveling path, and having two flanges for engaging a guiding track unit of the sliding member, and a shield fixed on the seat. Movement of the sliding member along the first traveling ...

A mobile device including: an input interface for user control of the device; a battery for powering the device; a printhead for printing onto a media substrate; a media cartridge for storing a quantity of the media substrate; and, a media feed path for feeding the media substrate past the printhead; wherein, the battery is positioned between the media cartridge and the input interface.

A printer having a pagewidth printhead assembly and a capping mechanism. The printhead assembly has a single pagewidth printhead and ink ejection nozzles located along the printhead for delivering ink onto print media as it is transported past the printhead. The capping mechanism has a capping member having a length corresponding substantially to that of the printhead and located in a non-capping first position spaced-apart from the printhead, a first actuating mechanism arranged to move the pri...

An ink jet printing apparatus includes a maintenance device configured to minimize the occupied space. The maintenance device includes a movable cap carriage supporting a cap and including two guide pins. The cap is engageable with an ink jet head of the ink jet printing apparatus. A cover surrounds the cap carriage and includes two guide slots receiving the two guide pins of the cap carriage, respectively. When a printing carriage engages a printing carriage engaging member of the maintenance d...
