  • Patent number: 7063470
    Abstract: A printer media supply spool adapted to allow the printer to sense type of media, and method of assembling same. The supply spool comprises a shaft having a supply of media ribbon wound thereabout. A transceiver unit is disposed proximate the shaft. The transceiver is capable of transmitting a first electromagnetic field and sensing a second electromagnetic field. A transponder including a semi-conductor chip is integrally connected to the shaft and has encoded data stored in the chip indicative of the type of media ribbon. The chip is capable of receiving the first electromagnetic field to power the chip and then generating the second electromagnetic field as the chip is powered. The second electromagnetic field is characteristic of the data stored in the chip. The transceiver unit senses the second electromagnetic field, which second electromagnetic field has the data subsumed therein.

  • Patent number: 7031012
    Abstract: This invention provides a printing apparatus which controls to inhibit any inadvertent write to a memory in an expendable so as to securely manage the exchange timing and the like of the expendable. For this purpose, the expendable such as a toner cartridge or the like comprises a rewritable nonvolatile memory (21) which holds information indicating whether or not its service life has expired. When the toner cartridge is attached to the printing apparatus, it is ready to communicate with a printer engine controller in the printing apparatus, and write to the nonvolatile memory (21) can be made in accordance with an instruction from a control unit. A lock functional unit (21a) writes information indicating write inhibition at a predetermined address in the nonvolatile memory (21), thus inhibiting write to the address position that stores the information indicating whether or not its service life has expired.

  • Patent number: 6903837
    Abstract: In predicting a quantity of a printing product necessary for printing a document, the document is stored in its entirety as digital data. Each page of the document is divided into bands of the digital data. From the digital data, a table of limited capacity is created, which describes at least part of a monochromatic component of one of the bands, with the monochromatic component corresponding to the printing product and each cell of the table representing at least a pixel. A number of switched-on pixels in the table is counted, with a switched-on pixel corresponding to a pixel for which a portion of the printing product must be ejected. Before enabling or demanding printing, a necessary quantity of the printing product is derived from a number of switched-on pixels corresponding to each band.

  • Patent number: 6388693
    Abstract: An apparatus for printing graphic images on sheet material has a thermal print head with a linear array of heating elements pressed into engagement with an ink web overlying the sheet material on a platen. The platen extends in the lengthwise direction of the print head across the width of the sheet material, and is rotatably driven to in turn drive the sheet material with the ink web relative to the print head. A removable cassette having a predetermined length of ink web bearing a printing ink is mounted adjacent to the print head with the ink web interposed between the sheet material and the print head for printing the graphic images on the sheet. A supply spool carrying the ink web is rotatably mounted in the cassette, and a take-up spool is also rotatably mounted in the cassette for receiving the ink web from the supply spool upon passage between the platen and print head.

  • Patent number: 6239879
    Abstract: Contactless power and communications links are established between a printer engine and a peripheral device installed on a replaceable printer component. For peripheral devices incorporated within or on the replaceable component, power is inductively transferred from a primary winding on the printer engine to an adjacent secondary winding on the replaceable component without the use of direct physical contact between electrical conductors. In addition, communications between the printer engine and at least one peripheral device on board the replaceable component are provided without making direct physical contact between electrical conductors. The communication task is accomplished in one of several ways. For a first embodiment of the invention, control signals are sent from the printer engine to the replaceable component over the inductive power coupling circuit by switching between two frequencies of alternating current applied to the primary winding on the printing engine.
