6.2.1 OVERVIEW
Only one original can be placed face-down on the original table.
Original set sensor [A]: Detects the leading edge of the original. Then the machine stops
original feed for 1 second (Delay 1). This gives the user time to put the paper straight. This
sensor also functions as a width sensor, with the original width sensors (not shown) below
the original feed table.
! Delay 1 can be adjusted. User Tools > System Settings > General Features >
Original Feed Delay 1.
Original feed roller [B]: Feeds the original to the registration sensor [C].
Registration sensor [C]: When this detects the leading edge of the original, the machine
stops original feed for 1 second (Delay 2). This gives the user time to check that the original
is straight. If the original is not straight, the user can push the “Scanner Stop” button to stop
original feed, remove the original, and try again.
! Delay 2 can be adjusted. User Tools > System Settings > General Features >
