■ Cassette paper feed
● Roller separation method
This product employs the separation roller method to avoid multi-feeding.
This method prevents multiple sheets from being fed by the driven separation roller. The separation roller is driven by the pickup
roller.
When normally operated
The separation roller is driven by the pickup roller to feed paper. By this, the separation roller rotates in the paper feed direction.
When multiple sheets are fed
Multiple sheets weaken friction between rollers, decaying the driving force conveyed from the pickup roller to the separation roller.
This product has the mechanism to regulate the separation roller rotation, which stops the roller rotation at multi-feeding under
weaker driving force conveyed from the pickup roller. This enables to avoid multi-feeding.
