An apparatus for advancing a sheet in a predetermined path is described. The apparatus includes a gripper for releasably grasping a lead edge of the sheet and a baffle for feeding the sheet into the gripper. The baffle includes a sheet directing member having a first facet and a second facet, with the second facet of the sheet directing member extending from the first facet and being angled towards the predetermined path of the sheet for deflecting the lead edge of the sheet being advanced into the gripper. One, two or more such two faceted sheet directing members may be coupled with one or more three faceted sheet directing members for further enhancing the sheet deflecting capabilities of the baffle. The baffle may be movable relative to the sheet path, and include a control member for moving the baffle between a first position engaging the lead edge of the sheet in the first position and second position in which the baffle is displaced from the path of the sheet.

Sheet control baffle for use in an electrophotographic printing machine

An apparatus for enhancing contact between a copy sheet and a developed image positioned on a photoconductive member includes a cam movable between a first position and a second position. The apparatus further includes a mechanism for moving the cam between its first position and its second position. Additionally, the apparatus includes a contact member being spaced apart from the copy sheet in a first mode of operation and being in contact with the copy sheet in a second mode of operation. Moreover, the apparatus includes a mechanism for positioning the contact member in its first mode of operation in response to the cam being moved to its first position, and in its second mode of operation in response to the cam being moved to its second position.

Developed image transfer assist apparatus having a cam mechanism

A transfer blade apparatus for ironing a sheet against the photoreceptor belt during transfer, and smoothing out deformities which cause deletions is disclosed. The transfer blades include a flexible tip to absorb the impact of the blade as it contacts paper, and a spring load to limit and control the force applied to the sheet. Sensors are also utilized to monitor and adjust the timing of the blades.

Transfer blade in an electronic reprographic printing system

An apparatus which advances a sheet through a transfer zone and into registration with information developed on a moving member. The sheet is advanced to a position wherein a leading portion thereof is immediately ahead of the transfer zone relative to the forward direction of movement of the moving member and a trailing portion thereof is within the transfer zone. The leading portion of the sheet forms a presentation angle of 7-10 degrees with the horizontal. The trailing portion of the sheet is advanced through the transfer zone at a first velocity and the leading edge of the sheet is advanced in a region immediately ahead of the transfer zone at a second velocity, which is less than the first velocity, so as to create a buckle in the leading portion of the sheet positioned immediately ahead of the transfer zone relative to the forward direction of movement of the moving member. The buckle functions to eliminate relative velocity between the photoconductive belt and any portion of sheet within the transfer zone so as to substantially eliminate slip between the sheet and the photoconductive belt.
