Abstract: A mobile device including: a printer for printing onto a print medium; and a stylus having a printhead tip for allowing a user to use the mobile device as a writing or drawing device; the stylus and the printer sharing at least one common ink reservoir.

Abstract: An integrated cartridge for installation into a mobile device, the cartridge including: an inkjet printhead including a plurality of inkjet nozzles; at least one ink reservoir for supplying ink to the printhead for ejection by the nozzles; and a capping mechanism for capping the printhead when it is not in use.

Abstract: A print cartridge for a mobile telecommunications device, the cartridge comprising: a drive shaft with a media engagement surface for feeding a media substrate along a feed path; and, a media guide adjacent the drive shaft for biasing the media substrate against the media engagement surface.

Abstract: A mobile device including: (a) an inkjet printhead; (b) a print media feed path for directing a print medium past the printhead in a feed direction during printing; (c) a capping mechanism including a capper moveable between: a capping position in which the capper is urged into a capping relationship with the printhead; and an uncapped position in which the printhead is able to print onto the print medium, wherein in the uncapped position the capper is displaced away from the printhead; (d) a force transfer mechanism connected to the capper and configured such that a force provided by an edge of the print medium as it moves relative to the feed path is transferred to the capper by the force transfer mechanism, thereby to at least commence movement of the capper from the capped position to the uncapped position prior to the print medium reaching the capper.

Abstract: A data synchronizer is provided for synchronizing data across two different clock domains in a manner that avoids additive jitter. The data synchronizer includes a synchronizer inputting a sampling clock and a data clock, and outputting an edge pulse. A synchronizer jitter lockout circuit inputs the edge pulse and the sampling clock and outputs a data sampling enable signal which never coincides with a data transition.
