The spine fold motor: left (M28) turns on and lowers the transport rollers 1, 2 on the left side of the cover,
releasing the cover from the nip. The cover grip solenoid (SOL1) energizes and opens the cover gripper
[3].
The cover motor: right (M12) reverses and rotates the buffer roller [1] at 500 mm/s and feeds the cover
[2] toward the switchback position. The cover is fed to a position at a prescribed distance away from the
cover registration sensor (S21) then the motor stops. This is the cover vertical position ("vertical" means
"direction of paper feed").
After the cover is aligned at the cover vertical position the gripper solenoid (SOL1) turns off and lowers the
cover gripper [3] which clamps the trailing edge of the cover.
After the trailing edge of the cover is clamped, the cover motor: right (M12) rotates forward and retracts
the buffer roller from the cover.
