Separation Roller Release
This new mechanism ensures that the feed and separation rollers do not stick
together at the start of a job just after the machine leaves standby mode.
When the feed roller reverses at the start of the job, a small arm pushes the feed
roller slightly forward so that it comes away from the separation roller.
If the rollers stay stuck together, the motor may not be able to turn the rollers.
When reversing at the start of the job, only a small amount of power is applied from
the motor, and this may not be enough to unstick the rollers.
