82 Chapter 4 - Operational overview EN
Lift: When no more paper is detected in the ADF input tray and the
trailing edge of the last page is detected by the form sensor, the last
sheet is ejected and the motor turns in a sequence which lifts the pick
roller assembly to standby or “paper loading” mode again.
The ADF will not function with the ADF door open. The paper path is
incomplete if the ADF lid is lifted from the glass.
ADF paper path and ADF sensors
The following figure shows the ADF paper path.
Figure 12. Document scanner path
The paper present sensor determines if paper is in the ADF. The form
sensor detects the top and bottom edges of the document. One other
sensor detects an open ADF door.
