  • Patent number: 8967783
    Abstract: What is disclosed is a system and method for printing a cancellation mark on a ticket using inks having thermo-reactive properties. One embodiment of the present method for printing a cancellation mark onto a ticket involves the following. A ticket, which has a security mark printed thereon, is received into a slot of a housing of a device which contains therein an inkjet printhead. The received ticket portion comes into proximity with an inkjet printhead configured to print a cancellation mark on the ticket using the thermo-reactive ink. The cancellation mark is printed to at least partially overlap the security mark. In one embodiment, a user activates a switch which causes the inkjet printhead to print the cancellation mark on the ticket upon the ticket having been inserted into the slot. Various embodiments are disclosed.

  • Patent number: 8960843
    Abstract: What is disclosed is a multi-function inkjet print system which prints with inks having thermo-reactive properties and which can further process media printed with thermo-reactive inks such that the various properties of the inks can be activated. One embodiment of the present print device comprises at least one thermo-changing element which resides in proximity to a transport path along which the media travels. The thermo-changing element effectively changing a temperature T of the media to: T?TL or T?TH, as desired. In various embodiments, a sensor is used for sensing a temperature of the media. A temp-normalizing element is positioned along the transport path and downstream of the thermo-changing element for changing a temperature of the media such that the media's temperature T can be normalized back to a range of TL<<T<<TH prior to the media being deposited into an output tray. Various embodiments of a user interface are disclosed.

  • Patent number: 8864254
    Abstract: What is disclosed is a multi-function system which receives media printed with ink having thermo-reactive properties and which processes the received media such that the ink becomes visually transparent. One embodiment of the present system comprises an input tray for receiving printed media into a transport path along which the media travels. A heating element resides in proximity to that transport path for changing a temperature T of the media to T?TH. In various embodiments, a temp-normalizing element is positioned along the transport path downstream of the heating element for changing a temperature of the media such that the media's temperature T can be normalized back to a temperature range TL<<T<<TH prior to the media being deposited into an output tray such that the processed media is no longer hot to the touch. A user interface enables a user to perform various functions. Embodiments of a user interface are disclosed.

  • Patent number: 8757744
    Abstract: What is disclosed is a multi-function system which receives media printed with ink having thermo-reactive properties with the ink being visually transparent on that media, and which processes that media such that the ink becomes visually perceptible. One embodiment of the present system comprises an input tray for receiving printed media into a transport path along which the media travels. A cooling element resides in proximity to that transport path for changing a temperature T of the media to T?TL. A temp-normalizing element is positioned along the transport path downstream of the cooling element for changing a temperature of the media such that the media's temperature T can be normalized back to a temperature range TL<T<TH prior to the media being deposited into an output tray. A user interface enables a user to perform various functions. Various embodiments of a user interface are disclosed.
