PAPER FEED
Separation Roller Release
[C]
The separation roller [A] is normally away from the feed roller [B]. When the paper
feed station is selected, the separation roller solenoid [C] contacts the separation
roller with the feed roller as explained on the previous two pages.
This contact/release mechanism has the following three advantages:
1. When the paper feed motor turns on, all the separation rollers in the three feed
stations rotate. If the separation roller is away from the feed roller, it reduces
the load on the paper feed motor and drive mechanism, and it also reduces
wear to the rubber surface of the separation roller caused by friction between
the separation roller and the feed roller.
2. After paper feed is completed, paper sometimes remains between the feed and
separation rollers. If the feed tray is pulled out in this condition, this paper might
be torn. When the separation roller is away from the feed roller, the remaining
paper can be removed from between the rollers.
3. When paper misfeeds occur around this area, the user can easily pull out the
jammed paper between the feed and the separation rollers if the separation
roller is away from the feed roller.
After paper feed and the paper feed clutch turns off, the paper feed motor still turns
the separation roller [A] in reverse. The separation roller, still contacting the feed
roller, turns the feed roller in reverse for 100 ms. Then, the separation solenoid
turns off.
