International Classification:

B41J 201

US Classification:

347104

Abstract:

A printing device having a frame, an input holding area, and an output holding area. The frame supports a printhead and a feed roller system for feeding print medium to the printhead. The input holding area is disposed on the frame. The output holding area is disposed on the frame. The input holding area holds print medium to be fed into the feed roller system. The output holding area has a support section to receive and support print medium output from the feed roller system. The support section of the output holding area has a bypass feed slot formed therein. The bypass feed slot is substantially straight. The bypass feed slot includes a first slot portion and a second slot portion adjoining the first portion. The second slot portion has a slot width different from the first slot portion.

International Classification:

B41J 2175

US Classification:

347 86

Abstract:

An ink tank and ink tank support structure which contains structural elements which are designed to permit proper installation of the ink in the ink tank support structure while minimizing the chances of improper installation of the ink tank in the ink tank structure. A primary ink tank seal is provided in the ink tank, and a relatively low compressive force seal is provided between the ink tank support structure and the ink tank to reduce leakage of fluid from tank and limit evaporation of fluid from the tank despite repeated insertions and removals of the ink tank from the ink tank support structure. A variable capacity ink tank and an ink tank with staggered height walls are disclosed, as well as a code reader for determining characteristics of ink tanks.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B41J 29393

US Classification:

347 19, 50 86

Abstract:

A particular ink tank, and therefore its characteristics, are determined by detecting the existence or absence of magnets at predetermined positions on the ink tank. The detection of the magnets is performed by hall effect sensors located on an ink tank holder of an image recording apparatus when the ink tank is positioned in the ink tank holder.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B41J 29393

US Classification:

347 19, 347 84, 347 86

Abstract:

A printer determines the characteristics of the ink of the replaceble ink cartridge by set of ink cartridges. Each ink cartridge is formed of a housing and includes marks on the exterior surface of the housing. The marks on the cartridge housing are arranged so that the marks on the several ink cartridges collectively form a pattern of marks. The printer electronically scans the pattern of marks, and automatically produces an indication in accordance with the pattern of marks to identify the brand and/or type of ink contained in the set of cartridges, the ink capacity of the cartridges, as well as to verify that an appropriate combination of cartridges has been installed. Printer performance characteristics, such as expected print yield, can be determined based on the indication produced by scanning the pattern of marks.

International Classification:

B41J 2175

US Classification:

347 7, 347 86

Abstract:

A low ink sensing system is combined with an ink cartridge detection system to enable a more efficient ink jet printer. An ink container which supplies ink to an associated printhead is modified by the incorporation of two light directing elements, in the preferred embodiment, a curvilinear prism-like structure and a curvilinear roof mirror, into a transparent wall of the container housing. The cartridge, comprising the ink container and associated printhead, is mounted on a scan carriage. Periodically, the carriage is conveyed to a sensing station comprising a pair of light sources and a commonly used photosensor. A first light source is energized and a beam of light is directed to a location where the curvilinear roof mirror would be positioned if the cartridge is present. If the cartridge is absent, lack of a reflected return signal is sensed, indicating a cartridge has not been inserted. Print operation is halted until a cartridge is inserted.
