No. Name Function/ Operation
1 Pickup roller Picks up a document and feeds it to the paper feed roller.
2 Paper feed roller Performs the paper feed operation of documents.
3 Separation roller Separate a document to prevent against double-feed.
4 No. 1 resist roller (Drive) Performs resist of document transport.
5 No. 1 resist roller (Idle) Applied a pressure to paper and the resist roller, and provides transport power of the resist roller to paper.
6 Transport roller 1 (Drive) Transports paper from No. 1 resist roller to No. 2 resist roller.
7 Transport roller 1 (Idle) Applied a pressure to paper and the transport roller, and provides the transport power of the transport roller to paper.
8 No. 2 resist roller (Drive) Make synchronization between the lead edge of a document and the scan start position.
9 No. 2 resist roller (Idle) Applies a pressure to paper and the resist roller, and provides transport power of the resist roller to paper.
10 Transport roller 2 (Drive) Transports paper from the platen roller to the transport roller 3.
11 Transport roller 2 (Idle) Applies a pressure to paper and the transport roller and provides transport power of the transport roller to paper.
12 Transport roller 3 (Drive) Transports paper from the transport roller 2 to the paper exit roller.
13 Transport roller 3 (Idle) Applies a pressure to paper and the transport roller and provides transport power of the transport roller to paper.
14 Paper exit roller (Drive) Discharges paper.
15 Paper exit roller (Idle) Applies a pressure to paper and the paper exit roller and provides transport power of the paper exit roller to paper.
