SYSTEMS AND METHODS FOR IMPLEMENTING ADVANCED STRIPPING OF IMAGE RECEIVING MEDIA SUBSTRATES IN IMAGE FORMING DEVICES

摘要

A system and method are provided implementing advanced stripping of image receiving media substrates, including substrates involved in any cut-sheet image forming process in an image forming device that includes a pressure nip necessitating an ability to reliably remove the sheets of image receiving media substrate from a conformable belt and/or roller surface. An appropriate peel force is applied to and opposite side of the image receiving media substrate that effectively peels an image receiving media substrate and image combination from an intermediate transfer belt downstream of a conformable transfer nip. A relatively small diameter stripper roller is positioned downstream of, and in close proximity to, the conformable transfer nip as an apparatus by which to effect application of the appropriate peel force. The small diameter stripper roller has a contact surface formed of an appropriately tacky material, including certain silicone materials, to apply the peel force.

主权项

1. A system for transporting image receiving media in an image forming device, comprising:
an imaging member; an opposing member, the opposing member exerting a force on the imaging member to form a transfer nip in which images formed on the imaging member are transferred to a first surface of an image receiving media substrate introduced into the transfer nip; a stripper roller positioned downstream of the transfer nip in a process direction, the stripper roller (1) forming a stripping nip through interaction with the imaging member, and (2) exerting a peeling force on the image receiving media by contact with a second surface of the image receiving media, the second surface of the image receiving media being opposite to the first surface; a mechanical component that moves the stripper roller between a first position and a second position, the first position being in contact with the imaging member to form the stripping nip and the second position opening contact between the stripper roller and the imaging member; and at least one stripping device in physical contact with the stripper roller downstream of the stripping nip in the process direction to strip the image receiving media from contact with the stripper roller, the at least one stripping device comprising a plurality of stripping ribs interspaced along a span-wise length of the stripper roller.
