A scanning device such as a printer has a trapezoidal carriage support beam which permits a compact juxtaposition of the carriage slider rod, the printhead, a drive belt and an encoder device. A second slider mounting for the printer carriage includes a bushing incorporating a part-spherical portion and an arm which engage with corresponding parts of the carriage.

Beam for supporting a carriage

A carriage slider rod is mounted on a steel beam by means of brass support elements. The support elements are first riveted to the beam and then have precisely aligned V-shape grooves machined therein to provide accurate location for the slider rod. The slider rod is screwed to the beam using central bores passing through the support elements. To fix the support elements to the beam, they are first located in respective apertures and then deformed by a clenching tool, one jaw of which passes through an adjacent aperture in the bottom wall of the beam.

A modular printer chassis, particularly for large scale printers, includes a lower media module which provides a rigid platen media support surface connected to an upper scanning carriage support module by a plurality of fasteners which are tightened at the time of assembly to thereafter permanently hold the modules, which are accurately positioned with the aid of a gauge at the time of assembly, in place so that the accurate inkjet printhead to media spacing in the print zone is maintained.

A storage container for storing inkjet cartridges, when removed from the carriage of a printer, having a capping housing for holding one or more caps, associated with each cartridge, for capping the printhead of the cartridge, wherein the caps are easily removable from the storage container by a user. The provision of manually removable cap allows the cap of a storage container to be matched to a particular cartridge having a specific printhead, ink formulation and lifetime. This ensures the efficacy of the cartridge is maintained during storage and prevents contamination of one cartridge by ink residue that may be left on a cap by another cartridge, which can damage the printhead due to chemical interaction between the different ink formulations.

Storage container for inkjet cartridges having removable capping means and a method for storing inkjet cartridges

A storage container for storing inkjet cartridges, when the cartridges are removed from the carriage of the printer, having a housing for simultaneously holding a plurality of inkjet cartridges and associated capping means. Preferably the cartridge housing has a plurality of compartments each having a number of biasing means for holding a cartridge against datums in the compartment. A set of components for holding a plurality of inkjet cartridges comprising a first cartridge holder adapted to be mounted on a carriage of an inkjet printer, and a second cartridge holder adapted to be mounted in a storage container for storing inkjet cartridges. Apart from mounting adaptations, the first and second inkjet cartridge holders comprise substantially common structural features so that cartridges are stored in substantially the same manner in which they are mounted on the carriage of a printer. This ensures that their efficacy will be maintained during storage and also enables components from the printer to be reused so that the design and manufacturing costs for the storage container are reduced.

Storage container for a plurality of inkjet cartridges and a method for

A storage container and method of storing inkjet cartridges and removable capping means therefor in which the order of their insertion and/or removal is controlled. Preferably, both the order of insertion of a cartridge and its capping means and the order of removal of said cartridge and capping means are controlled so that a cap and a printhead of a cartridge engage and disengage by the movement of the printhead towards or away from the cap thus preventing damage to the printhead by movement of the cap or any of the other components of a service module against the printhead. A rotatable arm mounted on the storage container which abuts a cartridge and obstructs the removal and/or insertion of the capping means is disclosed for controlling said order of insertion and removal.
