Roller functions●Pickup roller (Trays 1–5): This roller picks up paper from the paper trays.●Forward roller (Trays 1–5): This roller presses against the reverse roller and transports paper from the pickup roller to the feed roller.●Reverse roller (Trays 1–5): This roller presses against the forward roller and transports only one sheet of paper to the feed roller. When the pickup roller picks two or more sheets of paper, the load of the torque limiter on the reverse roller is heavier than the frictional force between the sheets of paper. As a result, the reverse roller is stopped and the lower sheet of paper does not advance any further.●Feed roller: This roller transports the paper sent from the forward/reverse roller to the registration roller.●Registration roller: This roller aligns the leading edge of the paper and transports the paper to the transfer roller.链接:https://pan.baidu.com/s/1_FVQPEcgZ-5obJc-Blk7ow 提取码:cqvm
