6.2.6 SCANNING MECHANISM

In this machine, the scanning unit [A] is above
the original feed path [B]. This eliminates copy
quality problems caused by foreign objects
falling into the scanner.
This machine also uses a contact image
sensor [A] (CIS System !), which scans
black and white originals up to 926 mm
(36 ") wide at 600 dpi.

The original moves past the scanning unit.
So, to increase the scanning speed of this
machine, the CIS consists of 16 blocks of
self-focusing lenses [B] arrayed in a
straight line.
