This application is a U.S. National Stage Application of and claims priority to International Patent Application No. PCT/US2013/057086, filed on Aug. 28, 2013, and entitled “CARTRIDGE COMPRISING AN AUTO-DESTRUCT FEATURE,” which is hereby incorporated by reference in its entirety.
Original authentic cartridges can be defined as being manufactured and sold through channels that are authorized by original equipment manufacturers (OEMs) of the cartridge and corresponding printers. Buyers may associate these cartridges and their contents with a certain level of quality. These authentic cartridges may also fall under certain product warranties provided by the OEMs.
In certain instances, cartridges are refilled, reused or tampered with by unauthorized third parties, for example after the original contents are substantially exhausted. It may be undesirable to associate such modified cartridges with a quality or warranty offered by the OEM.
For the purpose of illustration, certain examples constructed in accordance with this disclosure will now be described with reference to the accompanying drawings, in which:
In the following detailed description, reference is made to the accompanying drawings. The examples in the description and drawings should be considered illustrative and are not intended as limiting to the specific example or element described. Multiple examples can be derived from the following description and drawings through modification, combination or variation of the different elements.
The cartridge 2 includes a carrier 5A that carries an authenticity verification code 3A. The carrier 5A can be disposed on the outside or inside of the cartridge housing 2. In one illustrative example the carrier 5A includes a circuit for storing an authenticity verification code 3A. In another illustrative example the carrier 5A includes a label for having an authenticity verification code 3A imprinted thereon. In further examples the carrier 5A includes a combination of a label and a circuit.
The authenticity verification code 3A allows a third party to verify that the consumable material is from a trusted source by contactless scanning of the authenticity verification code 3A and matching it with a corresponding comparison code. Such comparison code may be stored on a distant computing device other than the printer, in one example on a distant network connected server, for example in a list containing multiple comparison codes. For example, the decoded authenticity verification code 3A corresponds to a unique identity of the product, for example a serial number.
The cartridge 1 includes an auto-destruct feature 13 that renders the authenticity verification code 3A on the carrier 5A permanently unreadable at installation of the cartridge 1 in the host device. For example, the carrier 5A is adapted so that by installing the cartridge 1 in the host device, the authenticity verification code 3A is inherently damaged, as illustrated and explained with reference to
For example the authenticity verification code 3A is configured in accordance with at least one predetermined contactless communication standard. Such contactless communication standard may relate to RFID (Radio Frequency Identification), NFC (Near Filed Communication), proximity card-type technology, bar codes, QR codes, and others. In one example a decoded authenticity verification code 3A corresponds with a unique identity number or a unique serial number. In an example the carrier 5A is a read-only type. For example the carrier 5A includes a label having a bar code or QR code imprinted thereon. For example the carrier 5A includes an unpowered NFC tag. In line with the foregoing, the authenticity verification code 3A can be an optically scannable code such as a Quick Response (QR) code, or a non-visible code stored on a non-transitory non-volatile memory circuit having an RFID or NFC interface.
In the illustrated example, the cartridge 1 can include an additional interconnect circuit 4 to communicate with the host device. For example the interconnect circuit 4 includes a non-transitory non-volatile memory circuit that is to be read and/or written by a host device. Example interconnect circuits 4 include an EEPROM circuit or a secure micro controller. The host device is provided with a corresponding interconnect circuit to read the information from the cartridge interconnect circuit 4, and in some examples write information to it. The additional cartridge interconnect circuit 4 may store at least one second authenticity verification code that is to be read by the host device to establish an authenticity of the cartridge 1. The second authenticity verification code may include a unique identifier, for example a product serial number or the like. For example, the second authenticity verification code on the cartridge interconnect circuit 4 is to be matched to at least one corresponding second comparison code stored in a printer or network memory. For example the cartridge interconnect circuit 4 is to remain functional, at least until the cartridge life fully or partly emptied or until the end of life of the cartridge.
In one example the carrier 5A is not to be connected to a host device circuit. For example, the first authenticity verification code 3A is not readable or decodable by the host device, before nor after installation.
In one example, the carrier 5A is designed to allow contactless scanning of the authentication verification code 3A by a third party scan device that is not the host device. Such third party scan device can be a handheld, mobile computing device such as a smart phone or tablet that has a respective scan capability, or a dedicated scan device. For example the capability allows for scanning the authentication verification code 3A according to at least one suitable standard technique including RFID (Radio Frequency Identification), NFC, IR (Infrared), or Optical Scanning techniques such as bar codes, QR codes, etc. Depending on the chosen scan standard, the capability may include an optical sensor, an NFC or RFID transmitter, and a set of respective decoding instructions stored on a scan device memory. In a further example the scan device has a network communication capability to compare the decoded authenticity verification code 3A to a trusted party's list of pre-stored corresponding comparison codes, for example stored on a distant computing device such as a server. In one example the decoded authenticity verification code 3A is to be verified with a corresponding comparison code on an external server
A carrier 105A is provided on the outside of a housing wall 102B. The carrier 105A protrudes outwardly from the housing wall 102B. For example the carrier 105A is distanced from the interconnect circuit 104. For example the carrier 105A includes a raised platform. For example the authenticity verification code 103A is imprinted on a label on top of the carrier 105A. For example the carrier 105A is disposed on a wall portion 102B that is close to a front portion 121 of the cartridge 101, the front portion 121 being a portion that is first inserted in the printer at installation. This may avoid that hands are close to the carrier 105A when installing the cartridge 101.
In this example, the auto-destruct feature 113 is defined by the location and protruding shape of the carrier 105A. The carrier 105A is located so that it bumps against a corresponding printer engagement member at installation. For example the carrier 105A and/or authenticity verification code 3A need to be damaged to install the cartridge 101. This provokes damage to the carrier 105A and the authentication verification code 103A. In one example the carrier 105A includes break features to allow for easy disengagement, easy rupture or cutting of the authentication verification code 103A without needing to apply excessive manual force during installation.
Referring to
The cartridge 201 includes an auto-destruct feature to render the authenticity verification code 203A unreadable at installation. The auto-destruct feature is represented by the location of the carrier 205A and the authentication verification code 203A. Here, the carrier 205A is disposed in a toner travel path to cover the authentication verification code 203A with toner, once toner is released from inside the cartridge 201, for example at a first installation of the cartridge and/or when a toner dam is removed. In addition adhesive can be provided on the carrier 205A to adhere toner particles 211 and better conceal the authenticity verification code 203A. In a further example, the carrier 205 may include a label to better absorb toner particles.
The cartridge 301 includes a carrier 305A. An optical authentication verification code 311 imprinted on the carrier 305A. The carrier 305A is disposed in the toner travel path P so that the toner particles 311, once released, adhere to the carrier 305A, concealing the authenticity verification code 303A. The carrier 305A is disposed downstream of the toner dam 312, between the toner reservoir 307 and the toner transfer assembly 309, for example in the intermediate chamber 314. The carrier 305A can include a platform or an integral part of the housing. The carrier 305A can include a label with a print of the authenticity verification code 303A. The authenticity verification code 303A includes a standard machine readable optical code such as a QR code.
The housing 302 includes a window 325 to allow scanning of the authenticity verification code 303A through the window 325. The carrier 305A is disposed near or opposite to the window 325. The authenticity verification code 303A faces the window 325 so that it can be optically scanned through the window 325, from outside the cartridge 301, at least before removal of the toner dam 312. For example, the authenticity verification code 303A is readable by a smart phone having a respective scanning capability.
The cartridge 301 is provided with an auto-destruct feature. In this example the auto-destruct feature 313 is represented by the location of the carrier 305A in the toner travel path P. Once toner is released out of the reservoir 307 it will cover the authenticity verification code 303A with a layer of toner particles, at least partly concealing the authenticity verification code 303A, sufficient to render the authenticity verification code 303A unreadable. For example a suitable adhesive could be applied to the carrier 305A to facilitate toner particles adherence. In an example, the carrier 305A is adapted to absorb toner particles.
A carrier 405A is attached to the drum cover 437 and the housing 402. One side of the carrier 405A is attached to the drum cover 437 and another side is attached to the housing 402. In the illustrated example the carrier 405A is attached to the outside of the drum cover 437 and housing 402. An authentication verification code 403A is imprinted or stored on the carrier 405A. In one example, the carrier 405A includes a label and the authenticity verification code 403A includes an optical code. For example part of the optical code is imprinted where the label is attached to the drum cover 437 and housing 402. In another example the carrier 405A includes a contactless circuit such as an NFC tag storing the authenticity verification code.
In another example a carrier is attached to the inside of the drum cover 437 and housing 402. For example such carrier includes a contactless circuit, such as an NFC circuit. For example a label is attached to the drum cover 437 and the housing 402 and the circuit is attached the label.
In the example of
An auto-destroy feature 613 is represented the location of the carrier 605A on the toner dam 612. The carrier 605A is located on the cartridge 601 such that it automatically interferes with a printer-part. Such printer part may include any protrusion suitable to damage the first circuit 660 when removing the toner dam 612.
The knife 648 is disposed opposite to the toner dam 612, so that it damages the first circuit 660 when the toner dam 612 is pulled along the knife 648. For example the knife 648 is disposed opposite to the toner dam 612, for example between the carrier 605A and the pull handle 646, with a cutting edge 650 or point near or against the toner dam 612. The knife 648 is disposed such that once the toner dam 612 is pulled along the knife 648, the first circuit 660 will engage a cutting edge or point of the knife 648. By pulling the toner dam 612 out of the cartridge the first circuit 660 is permanently damaged, enough to render the authenticity verification code unreadable by a scanning device. In one example the first circuit 660 is cut through.
The cartridge 701 includes an auto-destruct feature 713. The auto-destruct feature 713 includes a second circuit 758 that is to apply a voltage across the first circuit 760 to damage the first circuit 760, therewith altering the authenticity verification code on the first circuit 760. In one example, the second circuit 758 is connected to electric circuitry of the toner dam drive 754. For example the second circuit 758 utilizes the same current source as the electromotor 755. For example the second circuit 758 includes at least one electrode. In another example the second circuit 758 is connected to another motor or current source of the cartridge 701.
In another example the second circuit 758 is to apply a magnetic field to the first circuit 758, in that way damaging the first circuit 760 rendering the authenticity verification code unreadable. For example the second circuit 758 includes a coil to produce the magnetic field. For example the second circuit 758 is to extend close to the first circuit 760, to damage the authenticity verification code without touching the first circuit 760.
The different example authenticity verification codes mentioned in this disclosure can be configured according to any suitable contactless or proximity machine reading standard including but not limited to one or any combination of NFC (e.g. ISO/IEC 14443, ISO/IEC 18092, ISO/IEC 21481, ECMA-340, ECMA-352), RFID (e.g. ISO/IEC 14443, ISO/IEC 18000, ISO/IEC 15693, ISO/IEC 18092, ISO/IEC 21481), proximity card reading (e.g. ISO/IEC 14443, ISO/IEC 15693,), bar coding (e.g. ISO/IEC 15416, ISO/IEC 15415), QR coding (e.g. ISO/IEC 18004:2000, ISO/IEC 18004:2006) and other contactless code reading technologies.
