M2SS PWB Paper size detection PWB Paper size detection
No. Name Function
1 Paper size detection plate Changes its own position in conjunction with the paper size (length) adjustment lever. By this
operation, the paper size detector detects the paper size.
2 Paper widht guide R Suppresses skew to the minimum by restricting the paper width.
3 Paper size detection rotation plate Changes its own position in conjunction with the paper size (length) adjustment lever. By this
operation, the paper size detection plate position is changed and the paper size detector detects
the paper size.
4 Paper size (length) guide plate Regulates the paper size (length).
5 Paper widht guide L By restricting the paper width, skew is restricted to the minimum.
6 Lift plate Lifts the paper to maintain the paper feed position at the fixed position.
7 Paper pickup roller Sends paper to the paper feed roller.
8 Separation roller Separate paper to prevent against double feed
9 Paper feed roller Feeds paper to the paper transport section.
10 Transport roller 8 (Paper feed tray 3)
Transport roller 5 (Paper feed tray 4)
Transports paper from the paper feed tray 3 to the transport rollers 9 and 10.
Transports paper from the paper feed tray 4 to the transport rollers 6 and 7.
11 Transport roller 10 (Paper feed tray 3)
Transport roller 7 (Paper feed tray 4)
Transports paper from the transport rollers 7 and 8 to the transport roller 11.
Transports paper from the transport roller 5 to the transport roller 10.
12 Torque limiter Provides a certain level of resistance power for the paper separation roller rotation to prevent
against double feed.
