Abstract:
An enclosure for an ink reservoir bag in an ink delivery system for an ink cartridge comprises a tray and a cover for the tray. The tray includes a bottom wall having opposite ends and opposite sides, end walls extending upwardly from said bottom wall at the opposite ends and side walls extending upwardly from the bottom wall along the opposite sides. One of the end walls of the tray has a pair of openings therethrough between the side walls to receive fill and exit ports of the reservoir bag.
Abstract:
A processor is provided for use with a marking material cartridge the processor having configurable logic for configuring the processor for use with an associated printing device. A print cartridge includes a housing defining a chamber for storing a marking material therein and a circuit on the housing. The circuit includes a memory portion storing data related to the marking material, an interface portion in operative communication with the associated printing device for communicating therewith, and a configurable execution unit including a network of gates which are programmable by first set of instruction primitives received into the circuit to define a first set of operation instructions executable by the execution unit during operation of the print cartridge of the associated printing device. A method is provided for adapting a print cartridge for use with a printer including providing a processor having configurable logic on the print cartridge, and configuring the configurable logic of the processor for operative compatibility with the printer. In one form, the configurable logic processor is a programmable logic device which is configured by opening fusible links between logical gates contained in the programmable logic device.
Abstract:
The invention relates to a process for the preparation of a dry toner powder containing a wax component derived from the use of an aqueous wax dispersion and formed using an evaporative limited coalescence process. Both dry and aqueous dispersed pigments may be used. The resulting toner provides properties desired in the next generation of toners including small uniform particle size as well as desirable anti-blocking and high-temperature anti-offset properties.
Abstract:
An ink jet cartridge lid has a body having a first planar side and a second planar side opposite the first side. The first planar side has a raised portion having a first angled end wall and a second angled end wall. A third, side wall and a fourth, side wall each connect the first end wall to the second end wall of the lid. The second planar side has a recess therein with projections for compressing a foam insert. The lid is installed onto an ink jet cartridge having an open-ended cavity and a foam insert disposed therein.
Abstract:
An interlock arrangement for selectively removably mounting an ink cassette in the chute of a printer carriage comprises an ink cassette including a notch or recess and an interlock clip selectively connectable to a side of a printer carriage chute and cooperates with the notch member to provide an interlock which allows insertion of the ink cassette into the chute and prevents insertion of an ink cassette that does not have a notch or recess.
Abstract:
An ink cartridge for insertion into a cartridge holder has an ink supply tube coupled therewith for delivering ink to the cartridge from a remote source, and a clamping device on said cartridge is operable to open the supply tube when the cartridge is introduced into the holder and to close the tube when the cartridge is removed from the holder.
Abstract:
An ink reservoir bag of flexible, plastic sheet material for an ink delivery system for an ink cartridge is constructed of two sheets of plastic material having peripheral edges bonded together to provide an ink chamber therebetween and has separate fill and exit ports opening into the chamber and respectively defined by a fill tube and an exit tube bonded to the bag between the peripheral edges thereof. Flexible tubing is connected to the exit port through a check valve interposed between the port and tubing, and a lure lock is interconnected with the fill tube to provide an injection sight for filling the bag. The bag is filled by connecting the tubing to a vacuum source, evacuating air from the bag and tubing, connecting the fill port to a source of ink and using the negative pressure to draw ink into the bag and tubing.
Abstract:
An ink container opener having a first member having an opening formed therein; and, a second member received within the opening of the first member. The second member further has an opening for receiving an ink container for separating a top portion from a bottom portion of the ink container.
Abstract:
An ink container for an inkjet cartridge comprises spaced apart side walls, a front wall, a rear wall and a bottom wall, and a partition dividing the interior into three ink chambers. Each chamber includes an outlet port in the bottom wall, and the front wall and bottom wall lie in generally perpendicular planes, and a planer guide wall extends between and at an angle to the front and bottom walls. Each chamber contains a block of ink absorbent material and a felt filter pad between the corresponding block and outlet port, and the container further includes a cover having a flat upper surface provided with serrations to enhance gripping the container.
Abstract:
An ink tank cartridge includes a housing having a chamber defined by a set of side walls, a lid, and a first surface. An outlet port is formed in the first surface for communicating ink from the chamber. An ink receiving member for holding the ink is received in the chamber and is held in compression between the side walls. A substantial portion of the surface of the ink receiving member is compressed, preferably more than ⅓of the total surface. The ink receiving member is held uncompressed between the lid and the first surface. A method of assembling an ink cartridge includes providing a housing and a porous ink storage element. The ink storage element is compressed by a set of side walls defining a chamber formed in the housing. The ink storage element is compressed within a range of about 0.5%-50%.
