Abstract: The invention is directed to a media tray for an imaging apparatus for receiving a sheet of media. The media tray includes a base having a first side region and a second side region, a first sheet support member, a second sheet support member, a first mechanism, a second mechanism, and a force applying mechanism. The first and second mechanisms pivotally couple the first and second sheet support members to the side regions of the base, respectively. The force applying mechanism applies a force on the first and second sheet support members such that each of the first and second sheet support members diverge upwardly and outwardly from the base. The force applying mechanism includes a first cam member or first spring mechanism positioned between the first sheet support member and the base and a second cam member or second spring mechanism positioned between the second sheet support member and the base.

Abstract: The invention relates to an apparatus for providing information to a printer controller in order to identify the type of printer cartridge installed in a thermal ink jet printer. The apparatus includes a printer cable containing a set of electrically-conductive wires connected to contacts in a printer cable connector. The contacts of the printer cable connector make physical connection to an identification circuit on the printer cartridge. The identification circuit includes an electrical conductor which is at an electrical reference potential. When none, or one or more contacts on the cable connector are in electrical contact with the electrical conductor of the identification circuit, a signal corresponding to the identification of the printer cartridge is produced which is used by the printer controller to determine the type of printer cartridge installed in the printer.
