Abstract: A printer for creating specialty-sized prints includes a printing mechanism, a cutter mechanism and a slicing mechanism. A media web or sheet is fed into the printer and is advanced by a media advancement mechanism in a media advancement direction. The cutter mechanism cuts the media transverse to the media advancement direction. The slicing mechanism slices the media parallel to the media advancement direction. The slicing mechanism includes a cam positioned on a camshaft and a slicer module. The slicer module is positioned adjacent the camshaft and includes a contact spring operatively spaced from the cam and a blade operatively spaced from the media. The media is sliced when an actuation mechanism rotates the camshaft so the cam pushes against the contact spring of the slicer module, which biases the blade against the media.

Abstract: An actively-controlled recirculating ink delivery system is provided that incorporates active control of pressures downstream of the printhead. This is achieved through the use of a device (such as a pump, return valve, combination thereof or similar devices) that provides active control of downstream ink pressures. A pressurized ink supply, pressure sensors, an air and heat exchanger are also provided, thereby improving start up, normal operation, purging and shut down procedures. Because the pressurized ink supply is not restricted to sit at a particular vertical distance below the printhead, backpressure may be changed quickly and easily through electronic control, and system priming is considerably quicker than with conventional air-pressurized systems.
