Abstract:
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.

Abstract:
A printing and peeling arrangement comprises an impression drum for supporting a print medium during application of a printing image thereto, and one or more rotating vacuum fingers for applying vacuum via suction caps to the print medium to peel the print medium from the impression drum after printing. The vacuum finger is mounted for radial motion towards the impression drum and thereby avoids impact damage onto the print medium from the edges of the suction caps that results from a purely rotational approach to the drum.
Abstract:
A duplex section (230) comprises a first retaining section (240) arranged to retain a first portion of a medium (20) received from a processing section (210), the medium having first and second faces; and a second retaining section (250) arranged to retain a second portion of the medium, wherein the duplex section is arranged such that the medium is held substantially flat by the first and second retaining sections (240, 250), the medium is linearly stretched by the first and second retaining sections (240, 250) while being held substantially flat, and while, or subsequent to, being stretched the medium is returned to the processing section with the first and second faces interchanged relative to the processing of the processing section.
Abstract:
A method of error correction in a printing system includes engaging a sheet of print media with a perfector arm and detecting a relative position of the perfecter arm with respect to the sheet of print media when the perfecter arm has engaged the sheet of print media, the detecting being performed using a homing sensor that is configured to sense the perfecter arm while the perfecter arm is engaged with the sheet of print media. The relative position of the perfecter arm with respect to the sheet of print media is compared with an expected relative position and any difference between the relative position and expected relative position is compensated for when feeding the sheet of print media with the perfector arm to a print engine.
