Presses the paper pickup roller onto paper.
Presses the paper pickup roller onto paper.
Drive the paper feed tray 1, 2, 3 and 4, and the
manual paper feed section.
Paper remaining detection
Changes its own position in conjunction with the paper size (length) adjustment lever. By this operation,
the paper size detector detects the paper size.
Suppresses skew to the minimum by restricting the paper width.
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.
Regulates the paper size (length).
By restricting the paper width, skew is restricted to the minimum.
Lifts the paper to maintain the paper feed position at the fixed position.
Sends paper to the paper transport section.
Separate paper to prevent against double feed
Feeds paper to the paper transport section.
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.
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.
Provides a certain level of resistance power for the paper separation roller rotation to prevent against
double feed.
