Provided herein is sheet inverter apparatus which includes a diverter gate which diverts the sheet to one of at least two paths, a first paper path, and a second paper path. The first and second path each include a rotatable nip assembly, the rotatable nip assembly including a nip drive roll and a nip idler roll positioned so as to define a nip therebetween, the nip serving as a rotatable axis around which the nip drive roll and the nip idler roll rotate to invert the sheet.

Dual flip over roll inverter

A sheet inverter apparatus improves the handling capabilities of high speed printers and copiers. The sheet inverter apparatus includes a rotatable support having an axis of rotation and at least first and second arms radiating outwardly from the axis of rotation. First and second nip assemblies are is mounted to the first and second arms respectively. The support is rotatable to adjust positions of the first and second nips about the axis of rotation. Advantageously, with this arrangement, the support is adjustable so as to permit the first and second nips to receive sheets of paper at one location, be positionally adjusted with the sheets of paper moving therewith, and located at a second location so as to deliver the paper to an outlet feed path. This positional adjustment allows for inversion of the paper.

Multiple nip inverter

A dual path, single reversing roll inverter driven by a single actuator includes a single reversing roller with two, diametrically opposed idler rollers. The configuration of the reversing roller and idler rollers forms a first nip and a second nip that are alternately used to accept sequential sheets from a paper path. The first and second nips discharge the sheets into respective first and second inverting paths. A method for inverting sheets using the dual path, single reversing roll inverter includes rotating the roller in a first direction to direct a first sheet through the first nip. The roller is then rotated in a second direction opposite the first direction to direct the first sheet from the first nip and into the first inverting path and to simultaneously direct a second sheet into the second nip. A gate alternately directs the sequential sheets into the first and second nips.

A machine which transports and processes print media can incorporate a vacuum chamber. The vacuum chamber can be within a print media transport device in order to maintain a print medium at a uniform predetermined distance from a print media processing device, such as an image printing device (e.g., an inkjet printer), an image scanning device, or a spectrophotometer). In one embodiment the vacuum chamber is located within a roller that transports print media past the processing device. In another embodiment the vacuum chamber is located on an opposite side of a belt that transports print media past the processing device. In each of the embodiments the size of the vacuum chamber opening, which defines the vacuum area on the transport device, and also the amount of vacuum pressure may be selectively adjusted depending upon the size and weight, respectively, of the print medium being processed.

A system and method for determining the registration parameters necessary for registration or edge detection processing to enable the flexibility of changing the color of backing to suit a given application. The method includes scanning the backing surface to obtain at least two sets of gray level values; (b) determining an average gray level for each of the two color channels; (c) selecting a registration channel based on the average gray level; (d) determining a gray level deviation for the registration channel; and (e) determining registration parameters based on the average gray level and the gray level deviation of the registration channel.

A method of reducing condensation in an image forming apparatus wherein after the image forming apparatus is turned on and the fuser is being heated, a device is used to heat post Fuser paper path elements to reduce the possibility of condensation within the copier.

An anti-condensation baffle unit having two members which correspond to each other, which copied paper is transferred between the two members by at least one idler roller, and at least one muffin fan attached to the baffle unit to cool the area surrounding the baffle unit and the paper that passes through the baffle unit. The baffle unit further includes a plurality of slots, positioned such that the edge of the paper will not be caught by and consequently jam, which allow the air blown from fan to contact the paper and allows ventilation throughout the copying procedure.
