NO. Name Function/Operation
1 Pickup roller Feeds paper to the paper feed roller.
2 Paper feed roller Feeds paper to the paper transport section.
3 Separation roller Separates paper to prevents against double feed.
4 U-turn roller Guide roller to transport paper.
5 PS follower roller Applies a pressure to paper and the PS roller to give the transport power of the PS roller to the
paper.
6 PS roller Synchronizes the document lead edge and the scan start position.
7 Transport follower roller Applies a pressure to paper and the transport roller to give the transport power of the transport
roller to the paper.
8 Scan front roller Transports paper from the PS roller to the scan rear roller.
9 Scan rear roller Transports paper from the scan front roller to the SWB roller or paper exit roller.
10 Transport follower roller Applies a pressure to paper and the transport roller to give the transport power of the transport
roller to the paper.
11 Transport roller in SWB pass section Transports paper from the SWB roller to the PS rear roller.
12 Transport follower roller Applies a pressure to paper and the transport roller to give the transport power of the transport
roller to the paper.
13 Paper exit roller Discharges paper.
14 Paper exit follower roller Applies a pressure to paper and the paper exit roller to give the transport power of the paper
exit roller to the paper.
15 SWB roller The transport direction is switched back to reverse paper.
16 Transport follower roller Applies a pressure to paper and the transport roller to give the transport power of the transport
roller to the paper.
17 Reverse gate Selects between discharging a document to the paper exit section and transporting a
document to the reverse tray.
