Operation During Film Compression-Feed
1. When the leading edge of the document enters the compression-feed area, LF
motor starts to rotate counterclockwise, as indicated by the arrow.
2. Planet gear (A), which had been free, moves to engage with drive gear (A). The
drive from the LF motor is then transmitted to the various gears, as shown in the
diagram, and the driving roller rotates as indicated by the arrow. Also, planet
gear (B) moves against the drive gear (B) and planet gear (C) moves against the
drive gear (C), such that the LF motor drive continues to be transmitted to the
paper feed roller and paper eject roller, without changing the direction of roller
rotation.
3. The rotation of the driving roller is transmitted to the sub-roller. These rollers
feed the films and press them against the document. At this time, the rotations
of the paper feed roller and paper eject roller continue uninterrupted.
4. When the trailing edge of the document leaves the compression-feed area and
the X-cutters finish cutting the film, the LF motor reverses to rotate
counterclockwise. Planet gear (A) again becomes free such that the driving
roller rotation stops and feeding of the films also stops.
