2.1 Mechanical Operating Principles
2.1.1 Description of Mechanisms (Border Mode)
1. When a document is inserted into the paper loading gate, the paper feed rollers feed
it to the driving roller.
2. As the document passes between the paper feed rollers, the paper size detector
determines its size (length and width).
3. When the document passes between the film cartridges it is sandwiched between
the upper and lower films in the compression-feed area, where the films and
document are compressed between the driving roller and sub-roller.
4. The compressed document and film is fed to the cutting area, where it is cut to the
document size detected by the paper size detector with borders added. It is then
transported to the next stage.
5. The laminated document is fed out of the eject gate by the paper eject rollers.

2.1.2 Feed and Compression Mechanisms
The feed and compression mechanism controls the motor drive to feed the document
into the film cartridge, compression-feed the films, and eject the laminated document.
When no compression-feed is applied while feeding a document into the film cartridge
or ejecting a laminated document, the LF motor rotates clockwise and the motor drive is
transmitted via gears to the paper feed roller and paper eject roller.
At this time, the planet gear (A) is free from the drive gear (A), such that the drive is not
transmitted to the driving roller.
During compression-feeding of the films, LF motor rotates counterclockwise to move the
planet gear (A) against the drive gear (A), such that the drive from the LF motor is
transmitted to the driving roller.
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.
