Abstract: A replacement drive roll having an integral bearing for easy replacement and universal usage in a printing machine. The roll member has a bearing (156) having a non-round outer race (157) for retention in a frame member and a non-round inner race (153) for engagement with a driveshaft on one end. The opposite end has a locking member (159) for preventing axial movement along the shaft. The roll assembly has elastomer bands stretched around the outer circumference to form the drive surface of the roll. The roll unit is easily replaced and can be used in numerous locations thereby reducing parts inventory requirements.

Abstract: The duplex path loop (100) has an acceleration nip cooperating with a belt transport and re-time nip to allow duplexing of sheets while minimising skipped pitches on the photoreceptor. As each sheet to be duplex printed is removed from the process path after first side imaging, the path is accelerated to create a gap between it and subsequent sheets. The sheet is then stalled or slowed in a re-time nip, while subsequent sheets to be duplexed are simultaneously driven by the same transport, the first mentioned sheet being reinserted into the process path at the proper time for receiving the second side image before the arrival of the second sheet at the re-time nip. Subsequent duplex sheets are handled in the same manner so that duplex copies are interleaved or otherwise reinserted into the process path with first side copies so that skipped pitches on the photoreceptor are minimised.

Abstract: PROBLEM TO BE SOLVED: To provide universal drive roll parts low in cost, very compact in size and usable even in the different position of a printing device. SOLUTION: This drive roll and shaft bearing incorporate of type assembly are provided with the roll main body member 152, a shaft lock member 159 arranged on a first end section of the roll main body member 152 and arranged with the driving roll in the shaft direction along the shaft, and a bearing member attached to an end part of the roll main body member 152 opposite to a shaft lock member 159, extending across the roll main body 152 and forming the mount-supporting material.
