*1: Sheet feeding processes

a.Automatic Sheet Feeding (online operation)

Sheet tray motor (M201) raises the sheet tray. Paper feed solenoid (SD201) and paper-feed MC (MC201) goes on, causing the paper-feed, feed, and double-feed-prevention rollers to turn. This action feeds sheets, one by one, into the stacker section. The rollers are driven by FNS conveyance motor (M1) via a timing belt.

Sheets are stacked as cover sheets onto paper from the copier, and the results are then processed by the FNS (single staple, double staple, or booklet generation).

b.Manual Sheet Feeding (offline operation)

Sheet tray motor (M201) raises the sheet tray. Paper feed (SD201) and paper-feed MC (MC201) goes on, causing the paper-feed, feed, and dou- ble-feed-prevention rollers to turn. This action feeds all of the sheets from the sheet tray into the stacker section. The FNS carries out the required finishing (single stapling, double stapling, or booklet generation).
