IMAGE FORMING APPARATUSES AND METHODS THEREOF

摘要

Image forming apparatus and methods are disclosed which include an intermediate transfer member to transfer images to media, an impression roller including a gripping device to receive the media, and a determination module to determine the length of the media held by the at least one gripper unit based on respective detections by first and second set of sensors.

主权项

1. A method of transporting media to an intermediate transfer member having an image transfer blanket in an image forming apparatus, the method comprising:
transporting media in a media receiving direction toward a gripping device of an impression roller; detecting a leading edge of the media by a first set of sensors disposed across from the impression roller; detecting whether respective portions of the media are present proximate to a leading edge of respective blade members of corresponding gripper units by a second set of sensors disposed across from the impression roller; and determining respective lengths of the media in contact with and held by a plurality of gripper units of the gripping device by a determination module based on respective detections by the first and second set of sensors.
