During a scan, media travels up the sliders. Media then pushes the sliders down and travels down the paper
path underneath the Scanbars and above the sliders.
There is a rib at the front of the sliders that is 0.25 mm high. This is to keep the scan surface at the Scanbar’s
focal length of 0.25 mm.
Original Protection (OPT sensor and OPT wheel)
An original protection algorithm has been implemented to preserve the originals before they crash or jam
irrevocably.
●
Two sensors in the side, monitor originals with excessive skew that could come into contact with media
path walls.
