An ink jet recovery device comprises an elastic cap that is movable between a retracted position, in which it is spaced from a recording head, and a contact position, in which it is pressed against and seals the recording head. The recovery device also includes a rotatable drive gear having a cam surface, with a retracting cam and a compression cam, for moving the cap. When the drive gear is in a first angular position the retracting cam moves the cap to its retracted position, and when the driv...

A capping mechanism for an ink jet print head, both of which are mounted on a carrier for lateral movement on a laterally extending guide rail by a motor controlled by a control device in a direction across a recording medium placed in an ink jet printer. The ink jet print head has a plurality of ink ejection nozzles for forming characters on the recording medium as it laterally moves across the recording medium under the control of the control device in response to the inputting of such charact...

In an ink jet type print recording apparatus, a predetermined number of pulses are first produced in a positive direction when gear disengagement is carried out to drive an line feed motor in a forward direction at an angular amplitude within a half of a gear tooth width. Subsequently, pulses whose number is twice as large as the predetermined number are produced in the opposite direction to drive the line feed motor in the reverse direction. Subsequently, a predetermined number of pulses are pr...

A service station for use in servicing one or more inkjet print cartridges includes a service station sled assembly movably attached to a service station chassis. In one embodiment, the service station includes a sled assembly that includes a cap for enclosing a printhead of a print cartridge, a sled carrier on which the sled assembly is positioned, a cam follower structure including a cam follower, a cam positioned to interact with the cam follower, a mechanism for compliantly attaching the cam...

A service station for use in servicing one or more inkjet print cartridges includes a service station sled assembly movably attached to a service station chassis. The sled assembly includes at least one wiper and at least one cap. In one embodiment, the service station includes a cam and cam follower that interact to move the sled assembly. The cam is shaped so that movement of the cam to a first position causes each cap to contact a printhead of a corresponding inkjet print cartridge. Movement ...

In an ink jet printer, a carriage carrying print heads engages with a print head cap support member when the carriage reaches a position where the print heads are positioned opposite to a print head cap supported on the print head cap support member during its movement toward a capping position where the print heads are capped with the print head cap, and moves together with the print head cap support member. As the carriage moves further toward the capping position, an operating member is opera...

An ink jet recording head mountable in a recording apparatus, provided with a cleaning member capable of cleaning the ink discharging port formation surface of the recording head for discharging ink, in which there is provided for the ink jet recording head a concavity or a plurality of concavities in the traveling path of the cleaning member on the discharging port formation surface cleaned by the cleaning member at the upstream side in the traveling direction from the discharging port formatio...

According to the present invention, there is disclosed a capping device for an ink jet printer which is constructed such that a cap supporting member 14, adapted to move from the non-capping position to the capping position by the thrust action of a carriage 3, is arranged on the home position side of the ink jet printer so that the outer end part of the cap supporting member 14 is displaced toward the nozzle surface of a printing head 4 with the aid of a guide surface 15b having an inclined sur...

A cap actuation mechanism for placing a cap, movably mounted on a cap carriage of an ink jet printer maintenance station, into sealing engagement with the nozzle face of the printhead of the printer. The cap mechanism functioning in response to movement by the cap carriage which in turn is moved by printer's print cartridge carriage when it leaves a printing zone for servicing by the maintenance station.

A capping device for an ink jet printer includes a cap supported on a cap support member adapted to press the cap against a print head with a uniform pressure distribution despite variation in the positional relationship between the print head and the cap support member. The uniform pressure distributed is enhanced by supporting the cap by the support member in such a manner to permit the cap to pivot in at least two degrees of freedom. After the cap is sealed around an ink orifice of the printe...
