    Abstract: A system for printing on a multi-dimensional object includes a plurality of print heads, and a printing chase configured to receive an object holder for an object and provide accurate registration of the object. The system further includes an actuator configured to move the printing chase relative to the print heads. The system is configured to receive information corresponding to an object holder mounted on the printing chase, determine a position of at least one printable area using the retrieved information, receive information relating to print data to be printed on the at least one printable area, use the determined position of the at least one printable area to control a movement of the printing chase relative to the print heads, and operate the print heads to eject marking material onto the at least one printable area to print data on the at least one printable area.

  • Patent number: 10052888
    Abstract: A printer includes an ultraviolet (UV) curing device having UV light emitting diodes (LEDs) to cure UV curable inks ejected onto a surface after the surface travels past a plurality of printheads in the printer. A UV detector having UV sensors is positioned opposite the UV curing device so the UV sensors and UV LEDs are opposite one another in a one-to-one correspondence. A controller operates the UV curing device to direct UV light into the UV detector and receives electrical signals generated by the UV sensors. The controller compares these electrical signals to a predetermined threshold to identify defective LEDs in the UV curing device. The controller then determines how to move the UV curing device across the path of the surface to irradiate areas of the surface previously opposite the defective UV LEDs.

  • Patent number: 10052874
    Abstract: A method for forming an ink jet printhead comprises processing an epoxy adhesive such that negative effects from physical contact with particular inks are reduced or eliminated. Conventional adhesives processed using conventional techniques are known to gain weight and squeeze out when exposed to certain inks such as ultraviolet inks, solid inks, and aqueous inks. An embodiment of the present teachings can include processing of a particular adhesive such that the resulting epoxy adhesive is suitable for printhead applications.
