SEPARATION ROLLER RELEASE MECHANISM

In this model, the separation roller [A] is normally away from the feed roller
[B]. When the paper feed station is selected and the start key is pressed, the
separation roller solenoid [C] moves the separation roller into contact with the
feed roller as explained in the previous two pages.
This contact/release mechanism has the following three advantages:
1. When the paper feed motor turns on, all separation rollers in each feed
stations rotate. If the separation roller is away from the feed roller, it
reduces the mechanical load to the paper feed motor and drive
mechanism, and also reduces wear of the rubber surface of the
separation roller due to the friction between the separation roller and the
feed roller.
2. After paper feeding is completed, paper sometimes remains in the gap
between the feed roller and the separation roller.
If the feed tray is drawn out in this condition, it is possible for the
remaining paper to be torn.
When the separation roller is away from the feed roller, remaining paper
is released from the gap between the feed and the separation rollers.
3. When paper misfeeds occur around this area, the customer can easily
pull out the jammed paper between the feed and the separation rollers
because the separation roller is away from the feed roller.
