DOCUMENT JOURNEY THROUGH THE TRANSPORT
Now that you have experienced the scanner from the operator’s point of view we will walk you
through the scanner from the document’s point of view. We will follow the path of a document
from its start in the input elevator, to separation from the stack, to ultrasonic double-feed
detection, to rear side imaging, then front side imaging and finally output restacking. This
perspective allows us to talk about the various parts of the scanner transport in a logical
sequence. The instructor will describe important components that will be referred to later in this
course. This basic understanding of the scanner’s transport allows you, as the operator, to be
more comfortable with the equipment and more productive.
¾Note the green caution labels
¾Stage one: Input elevator
- Independently adjustable side guides for offset scanning
- Paper present sensor
- Lock/Unlock switch
- Long document wire bail
- The host scanning application can be used to set the elevator to four different
starting heights.
¾Stage two: Document separation from the stack
- Opening the pod
- Location and functions of the:
pre-separation pad
separation roller
feed module
- Demonstrate that there is a Gap Release button that lowers the separation roller to
allow feeding of very thick or damaged documents.
¾Stage three: Pre-imaging document transportation
- Review transport rollers, UDDS sensors and patch head sensors.
- Review printer baffle; remove front printer background strips and show front ink
blotters.
¾Stage four: Imaging
- Image Background. Remove and talk about scratches. Talk about white background
accessory and use.
- Imaging Guides (upper and lower). Talk about the white patch, removal of the
imaging guides, and how to clean imaging guides using Staticide wipes. Point out
that the upper imaging guide has ribs to prevent ink from smearing and the lower
imaging guide does not.
- Lamps. Not customer replaceable.
NOTE: The bottom lamps have a cover glass between them but the upper lamps do
not. Do not insert anything into the upper camera area.
