A medium-cutting device includes a medium-conveyance section to convey a medium in a medium-conveyance direction, a cutter to cut the medium conveyed by the medium-conveyance section, and a pushing part to push up a piece of the medium that is cut from the medium with the cutter.

Identifying printing substrate types

Devices and methods for identifying categories or types of print media in image forming apparatuses are disclosed. In an example method print media are advanced in a feeding direction to reach a cutting position, a cutter is advanced in a cutting direction, perpendicular to the feeding direction to cut the print media, friction between the cutter and the print medium is measured, and the print media are identified based on the measured friction.

Combination printer and cutting apparatus

A combination printer and cutting device for printing upon and cutting a web of media or tag stock into individual units. The device may cut vinyl, plastic, or RFID stock material as it moves through the printer in both back and forth directions. The device comprises a printer and a cutting apparatus that is further comprised of a carriage assembly and a movable cutter assembly. The cutter assembly is easily interchangeable and comprises a cutting element such as a wheel blade, and a pressure adjusting element for adjusting the amount of pressure applied by the cutting element to the stock material. Alternatively, the cutter assembly may be manufactured with a predetermined pressure load, but still permit an operator to adjust the depth of cut. The cutting apparatus is adaptable for use with both new and existing printers.

Bi-directional cutting modules

According to an example, a cutting module may comprise a carriage and a cutting blade, wherein the carriage may be capable of reciprocating movement along a cutting path. The carriage may be supported by a support structure and the cutting blade may have a fitting pin to engage with the carriage. During a first direction movement along the cutting path, the fitting pin may obtain a first cutting-edge angle. During a second direction movement along the cutting path, the fitting pin may obtain a second cutting-edge angle.
