 The hopper release cams and the ASF rollers are
keyed to prevent you from installing them on the drive
shaft in the wrong direction.
 Test the shaft fixing clip and opto-interrupter wheel to
make sure they’re installed securely and don’t slip off.
 Note that the black roller assembly goes on the right
side and the lighter-colored one goes on the left.
