A mount system for a monitoring device is disclosed. The mount system may include an extension arm attached to a device structure for housing the monitoring device. The mount system may include an alignment cup coupled to a support structure, wherein the extension arm is received through a through hole in a base of the alignment cup, and an oblong fitting attached to the extension arm opposite the device structure, wherein the oblong fitting is complementarily shaped to be received within the alignment cup to be received within the alignment cup, such that when the oblong fitting is received within the alignment cup, the device structure is aligned into a monitoring location. The mount system may include a dampening component between the support structure and the extension arm to bias the device structure into the monitoring location.

A print head assembly for a media processing device comprises: a print head including an interface and a latch receiver on an upper surface of the print head; and a print head carrier including: (i) a base plate having an opening to receive the latch receiver therethrough when the print head is positioned at a lower surface of the base plate; (ii) an adapter to engage with the interface of the print head; and (iii) a latch bar on an upper surface of the base plate, the latch bar slideable between a first position to engage with the latch receiver and lock the print head to the base plate, and a second position to disengage from the latch receiver and release the print head from the base plate.

A thermal demand printer for printing on media is a novel system which includes a case structure including a hinged cover panel, easily removable guide structures and media hanger, and a single central support wall to which the various components are attached. The printer includes a power supply circuit for receiving power from an external source and conditioning it for operation of the printer. An input device is provided for receiving command signals related to the operation of the printer. A control circuit for processing the command signals and generating corresponding control signals for controlling the operation of the printer and a printhead assembly for processing the control signals and generating corresponding control signals for controlling the operation of the printer are mounted in the case structure and coupled to the input device and the power supply circuit. The printhead assembly includes a printhead support structure which controls the printhead. A ribbon take-up spindle, method of operating the take-up spindle using a PMDC motor, and a spring wrap clutch device help to control the tension in the transfer ribbon used in the printer. The printer also includes a medial sensor and a method of sensing media by way of detecting the opacity of the media passing through the sensor. The printer includes a method of printhead control using double data loading and a method of accelerating and decelerating media relative to the printhead using pulse width modulation.

Ribbon drive for a thermal demand printer

A demand printer for printing on media includes a ribbon take-up spindle for accumulating spent printing ribbon and facilitating removal of the spent ribbon from the spindle. The spindle has a surface with a protrusion bore formed therethrough. At least one protruding segment extends through the protrusion bore. The protruding segment controllably projects away from the spindle surface for maintaining a space between a portion of the spindle surface and the spent ribbon accumulated on the spindle. A biasing structure is operatively associated with the spindle and the protruding segment for controllably biasedly directing the protruding segment through the protrusion bore in the spindle. A retracting structure is provided for controllably compressing and expanding the biasing means to controllably move the protruding segment through the protrusion bore.
