Abstract: A mixing drum includes a body defining a head aperture and a discharge aperture opposite the head aperture, a head coupled to the body and extending across the head aperture, and a mixing element positioned within the volume and coupled to the body. The head and the body define a volume. The body is formed from at least a first section and a second section. The first section overlaps the second section.

Abstract: A mixing drum includes a body defining a head aperture and a discharge aperture opposite the head aperture, a head coupled to the body and extending across the head aperture, a bearing member coupled to the body and defining a bearing surface surrounding the body, and a mixing element positioned within the volume and coupled to the body. The head and the body define a volume configured to contain a fluid mixture. The mixing element is configured to drive the fluid mixture toward the head when the drum is rotated in a first direction. The mixing element is configured to drive the fluid mixture towards the discharge aperture when the mixing drum is rotated in a second direction opposite the first direction. The head is made from a first material, and the body is made from a second material having a lesser density than the first material.

Abstract: A ribbon cartridge includes a cartridge housing, a supply spool, a take-up spool, a supply of ribbon, and a supply circuit. The cartridge housing includes a supply spool enclosure and a take-up spool enclosure. The supply spool is contained in the supply spool enclosure and the take-up spool is contained in the take-up spool enclosure. The supply of ribbon extends from the supply spool to the take-up spool. The supply circuit includes a memory containing supply information relating to the ribbon cartridge.

Abstract: A credential substrate rotator includes a substrate support, a substrate feeder and a substrate sensor. The substrate support is configured to support a substrate in a substrate support plane and rotate about a central axis. The substrate feeder is configured to feed a substrate along the substrate support plane. The substrate sensor includes a substrate position indicator that is aligned with the central axis and has first and second positions. The first position indicates an absence of a substrate from a predetermined location of the substrate support. The second position indicates a presence of a substrate in the predetermined location of the substrate support. Also disclosed, is a credential substrate processing module that includes a credential substrate rotator, a first data encoder and a module controller. The credential substrate rotator includes a substrate support configured to support a substrate in a substrate support plane and rotate about a central axis, and a substrate feeder.

Abstract: A printer includes a substrate input, a substrate transport, a printhead, a removable ribbon cartridge, a ribbon cartridge receiver, and a substrate output. The substrate transport is configured to feed a substrate from the substrate input along a print path. The printhead is positioned below the print path and is configured to print an image on a surface of the substrate. The ribbon cartridge is received in the ribbon cartridge receiver and contains a supply of print ribbon that extends between supply and take-up spools and over the printhead. The substrate can then be discharged through the substrate output.

Abstract: An identification card printer includes a card input, a card transport, a printhead, and a card output. The card transport is configured to feed a card from the card input along a print path. The printhead is positioned below the print path and is configured to print an image on a surface of the card. The card can then be discharged through the card output.
