5. Relay Roller Pressure Release

When the upper feed-in unit is raised to remove misfed originals, the relay
roller pressure is released.
Both arms of the upper feed-in unit have detents which allow the lower
relay rollers to press against the upper relay rollers when the upper feed-in
unit is down.
However, they release the roller pressure when the upper
feed-in unit is raised.
The safety switch (MS-1) is activated to open the circuit at the same time.
