Abstract: Techniques for liquid replenishment in a printer/plotter. An ink delivery system (IDS) is employed wherein the on-carriage spring reservoir of the print cartridge is manually and securely connected to the off-carriage reservoir. A pen cartridge that uses an internal spring to provide vacuum pressure is connected from an inlet port through a unitary coupler to an ink reservoir located off the scanning carriage axis. The coupler serves to align as well as to secure two mating valves to securely hold them together in an open latched position which is not intended to be modified or disconnected until the entire ink supply has been depleted. A replaceable ink supply module for providing replenishment of an inkjet printhead includes a collapsible bag, an enclosure box, a connective tube, and an on/off valve. These four components are incorporated into a composite sealed system which remains intact during shipment, storage, installation and operation.

Abstract: A printer carriage has a chute for removably holding a print cartridge, and includes a set of datums on a forward portion of the chute for positioning the print cartridge. A spring-loaded clamp is movable by a handle between an open position which allows easy insertion and withdrawal of the print cartridge from the chute, and a closed position which applies a clamping force against a back wall of the print cartridge. The clamping force is preferably applied in both a forward and downward direction against a lower portion of the back wall to securely hold the print cartridge in the chute against the datums, and to provide conductive contact through a plurality of electrical interconnects between the carriage and the print cartridge. A method of installation and removal of a print cartridge employs access along a primarily vertical path through an open top of the chute.

Abstract: An ink delivery system which includes a short form factor ink jet pen having a supply of ink for depositing on an ink receiving medium. An adapter is mounted to the short form factor pen to permit it to be removably mounted within a pen receptacle or stall dimensioned to receive a tall form factor pen. The ink jet cartridge includes a housing, a printhead mounted on the housing, datum surfaces on the housing for registering a position of the housing in a fixed, repeatable position in a first carriage structure, and a cartridge set of electrical contacts mounted to the cartridge housing and electrically coupled to the printhead. The cartridge set of electrical contacts is positioned on the housing for electrical contact with a corresponding first carriage set of electrical contacts when the cartridge is mounted in the first carriage structure.

Abstract: An ink replenishment kit and method for an inkjet printer includes a replaceable ink supply module providing replenishment of an inkjet printhead, The module includes a collapsible bag, an enclosure box, a connective tube, and an on/off valve. These four components are incorporated into a composite sealed system which remains intact during shipment, storage, installation and operation. A coupler is provided to securely attach a print cartridge inlet with the on/off valve to hold them together in an open position allowing ink to be replenished into the print cartridge from the collapsible bag.

Abstract: An off-carriage printing system with high performance tubing. The printing system includes a media transporting system for transporting a print medium along a medium path to a print area, a scanning carriage for holding a printing structure including a printhead, and a scanning apparatus for scanning the carriage along a scanning axis transverse to the media path at the print area. The system further includes fixed ink supply station including an ink reservoir. A fluid conduit for the flow of ink, interconnects between the ink reservoir of the fixed ink supply station and the printing structure, the fluid conduit including a length of hollow flexible multiple layer tubing routed such that a flexible loop is formed therein. The multiple layer tubing comprises at least one inner barrier layer to water vapor transmission from the ink, at least one barrier layer to oxygen permeability, and at least one outer barrier layer to water vapor transmission from the atmosphere.

Abstract: Acoustic noises are suppressed in a large format drafting plotter (10) utilizing a paper drive motor (22) mechanically coupled to a paper drive shaft (20) by a geared timing belt (26) from the motor to a pulley (24) on the drive shaft by suitably modifying the pulley. The pulley is modified by enlarging the drive shaft hole (38) in the center thereof so as to provide slip-mounting of the pulley on the drive shaft. A winged clamp (30) is provided, mounted on the pulley, and having a central portion (34) having an opening (36) therethrough for engaging a portion of the drive shaft and a tightening screw (40) for securing the winged clamp to the drive shaft. The winged clamp also has two opposed extensions (42), which are each maintained between a pair of bosses (44) on the outside surface (24a) of the pulley, and isolated therefrom by a pair of isolator pads (32) comprising a compliant material.
