Blanket replacement systems and methods useable with an image forming apparatus are provided herein. The blanket replacement system removes the blanket from the image transfer member and attaches the blanket to the image transfer member. The blanket replacement system includes a frame member, an engagement motor, and a rotation motor. The frame member holds a blanket having a lead edge portion on one edge and a trail edge portion on an opposing edge. The frame member further includes a lead edge clamp unit and a trail edge clamp unit that holds the lead edge and trail edge portions of the blanket and engages with an image transfer member. The engagement motor engages with the frame member and moves the frame member laterally in relation to the engagement motor. The rotation motor is connected to the engagement motor and rotates the engagement motor and the frame member.

Blanket replacement system and method thereof

A cast device useable with an image forming apparatus is provided. The cast device includes at least one tube and a cast body. The cast body includes the at least one tube implanted into the cast body using a combined casting process.

Cast device with implanted tubes

In one embodiment, a guide for installing a photoconductive film on to a photo imaging plate includes a movable channel located near the photo imaging plate, for example in a digital printing press. The channel has a bed and a pair of sidewalls extending parallel to one another along opposite sides of the bed such that the lateral movement and skew of a photoconductive film lying on the bed is constrained by the sidewalls. The channel movable between a first position in which an open end of the channel is away from the photo imaging plate and a second position in which the open end of the channel is immediately adjacent to and aligned with the photo imaging plate for installing a photoconductive film on to the photo imaging plate.

A cam follower is affixed to a rotary component that is in mechanical communication with a rotary source such that the cam follower travels along a path when the first rotary source is operating. The cam follower is in mechanical communication with a mechanical component such that, when the cam follower is engaged with a retract dwell section of either of a dynamic cam or a static cam, the mechanical component is retracted. The static cam may be positioned to allow the mechanical component to retract for a predetermined portion of the path.

A device for holding a photoreceptor sheet onto a drum of an electro-photography printing device comprises first and second holding surfaces that are configured to hold an edge of the photoreceptor sheet from opposite directions by pressing against the sheet in a substantially perpendicular direction with respect to the surface of the sheet, wherein at least the second holding surface is pre-loaded.

Device for holding a photoreceptor sheet

A roller device includes a cylinder member. The cylinder member includes wall member having a plurality of channels that are disposed within the wall member. The channels circulate a fluid therein to uniformly regulate a temperature of the cylinder member.

Regulating temperature of a roller device

A sheet processing system, comprising a number of drums for processing sheets, one of the drums comprising a seam area and a non-seam area, a gap between the drums, an actuator for displacing one of the drums for setting the gap, a manager, comprising a memory and a processor, that regulates the actuator current when the non-seam area passes through a nip so as to maintain a nip pressure, and signals the actuator to adjust the gap according to a predetermined gap setpoint profile when the seam area passes through the nip.
