Service Station For Use With Inkjet Printing Apparatus, Including Compliantly Supported Sled Carrier, Multi-Purpose Positioning Cam And/Or Reduced Footprint
Chan K. Nguyen - San Diego CA Lynn D. Palmer - Escondido CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
B41J 2165
US Classification:
347 32
Abstract:
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 follower structure to the sled carrier, and a motor adapted to move the cam. The mechanism for compliantly attaching provides a compliant support for the sled assembly that enables the sled assembly to be positioned in a capping position that ensures adequate contact between the cap and printhead, but that alleviates excessive forces that may otherwise build up between the sled assembly and the print carriage during capping as a result of moving the sled assembly too far in a direction toward the printhead. 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 of the cam to a second position causes the cap to move away from the printhead and moves the wiper into a wiping position.

400185
Abstract:
A multiple-function printing device provides for picking pages from a stack of sheets in an input feeder for roller-driven movement along a first path through a printing station to an output, and for picking pages from a stack of documents in an input feeder for roller-driven movement along a second path through a scanning station to an output, with at least a portion of the first and second paths being commonly shared, with a document deflector which, in a document scanning mode of operation, is pivoted into a lowered position generally parallel to a print station platen to constrain the top and bottom of curled documents exiting from the scan station so as to prevent an incipient paper jam. The deflector is actuated by a drive mechanism including a ball link and cranks connected to a common motor in a service station for capping and wiping print cartridges in the printing station.
