Abstract: An apparatus has a sheet path moving sheets of media within the apparatus and a curling/decurling station positioned along the sheet path. The curling/decurling station has a first set of rollers that impart or remove curl from a first type of sheets of media moving along the sheet path, and a second set of rollers that impart or remove curl from a second type of sheets of media moving along the sheet path. The first type of sheets have a different stiffness than the second type of sheets and are most effectively curled/decurled differently by the different sets of rollers.

Abstract: A drive roll/idler roll nip release mechanism utilizes the motor used for the drive nip, coupled with one-way clutches, to power the nip release as a sheet is handed off to a downstream nip. A drive shaft is coupled to a first one-way clutch in one direction and an idler cam shaft is coupled to a second one-way clutch in the opposite direction. This allows the idler cam shaft to be driven only when the motor is reversed, and the drive shaft to be driven only when the motor is moving forward. The one-way clutch on the drive shaft allows the drive wheels to freewheel when the motor is reversed in order to engage the nip release. Thus, the nip release is activated while the drive nip continues to rotate in the direction of sheet motion.

Abstract: An apparatus for registering a sheet along a transport path, including a plurality of spaced apart sheet feeding nip sets of plural sheet feeding nips in the sheet transport path, the plural sheet feeding nips of the sheet feeding nip sets comprise plural drive wheels and plural mating idlers, steerable drive mechanism for changing the drive wheel to idler alignment to thereby transport the sheet along the paper path while imparting a lateral motion to the sheet as it is transported along the paper path.

Abstract: A system for automatically releasing selected plural sheet feeding nip sets spaced along a print media sheet feeding path of a printer, wherein the idler rollers are rotatably mounted on common idler shafts and a selectable partial rotation system driven by a single low cost motor is flexibly connected to those plural idler shafts to partially rotate eccentric lift cams on each idler shaft into the underlying surface as to lift the idler shaft and thereby move the idler rollers away from their normally mating sheet feed rollers to release all the sheet feeding nips, enabling sheet deskew, inversion, acceleration, deceleration, or sheet jam clearance in that selected area of the sheet feeding path.

Abstract: An ink image producing machine has (a) imaging devices, including at least one ink jet print head and an image receiving station for producing an ink image on a heated substrate; (b) a substrate handling assembly including holding devices for holding supplies of substrates, and transport feeding devices for transporting and feeding substrates in a substrate direction towards the image receiving station; (c) a first substrate heating assembly located upstream of the image receiving station for initially heating each substrate being fed and transported from the holding devices; and (d) a second substrate heating assembly located downstream of the first substrate heating assembly and upstream of said image receiving station, relative to the substrate feeding direction, for controllably re-heating each substrate, initially heated by the first substrate heating assembly, to a desired ink image receiving temperature.

Abstract: A rotary power tool incorporates a remotely actuated chuck device. An engagement surface, such as a threaded or helical surface, is defined on an outer circumference of the chuck device over an axial length thereof. An actuator member is disposed concentric and rotatable relative to the engagement surface. In an actuation mode, the actuation member is brought into engagement with the engagement surface so that rotation of the actuator member drives the chuck device axially between gripping and release positions.

Abstract: A rotary power tool has a remotely actuated chuck device. A hydraulic actuating system is incorporated in the power tool and is configured to move the chuck device between the gripping and release positions upon hydraulic fluid being supplied to at least one hydraulically driven actuator mounted relative to the tool casing and engaged with the chuck device to move the chuck between gripping and release positions.

Abstract: A rotary power tool is provided having a remotely actuated chuck device. The chuck includes an outer sleeve member that is axially movable relative to the drive spindle between a gripping and release position. A sleeve actuating device is provided having a first member engaged with the outer sleeve member and which extends generally radially outward from the drive spindle or chuck. The first member is movable in a direction so as to move the outer sleeve member between the gripping position and release position. The sleeve actuating device includes an actuator member configured with the first member to move the first member upon an external force being applied thereto. The actuator member is generally perpendicular to the axis of the drive spindle and may be limited in length to be confined in the perimeter of the casing. In this manner, an operator can move the chuck device between the gripping release positions at a location remote from the chuck device and drive spindle.
