Abstract: A media processing device includes a platen roller, a printhead, a media exit, a first sensor disposed proximate to the platen roller, a second sensor disposed proximate to the media exit, and a logic circuit. The printhead is configured to form a nip with the platen roller. The logic circuit is operatively coupled to the first and second sensors and is configured to discriminate between a normal operation of the media processing device, a media jam error, and a media wrap error based on outputs from the first and second sensors.

Abstract: Pivoting Cutters are disclosed herein. An example pivoting cutter includes a printing device, comprising a frame; a printing assembly including a printhead and a platen roller; and a cutting assembly including a cutting blade and a media scraper, the cutting assembly is disposed on a mounting apparatus which is mated to the frame by a hinge and has an engaged position and a disengaged position, in the engaged position, the cutting assembly is immediately proximate to the printing assembly, such that the media scraper is configured to guide a printed media off the platen roller and to the cutting blade, and in the disengaged position, the mounting apparatus is rotated about the hinge, and a distance between the cutting assembly and the printing assembly is increased.

Abstract: A printer is disclosed that includes a platen roller assembly, a frame, and a drive assembly. The drive assembly is operatively coupled to a first mating structure at a proximal end of an axle of the platen roller assembly to automatically rotate the axle via the proximal end of the axle during a printing operation. The axle is manually rotated in situ via a second mating structure at a distal end during an operation to remove linerless media wrapped around the platen roller assembly.

Abstract: A fuel heater for use with an engine having a liquid cooling system has an extractor and a heat exchanger. The extractor has a coolant diversion conduit defining a diversion across the coolant flow path and toward the upstream end. The extractor further has a coolant return conduit defining a return opening across the coolant flow path and oriented toward the downstream end. The heat exchanger forms a coolant jacket through which the fuel line is directed. Pipes conduct coolant between the extractor and the heat exchanger.
