Detecting The Presence/Absence Of An Original In The Manual Feeder - Canon DADF-Q1 Service Manual

Chapter 2
Be sure to adjust the slide guide to suit the original size when making copies.
Otherwise, the original is likely to move askew.
c. Slide Guide Positioning Member
The rail of the slide guide is provided with notches to make sure that the slide guide stops to suit a specific default original size. Some of these points representing
differing paper sizes, however, are close enough to allow the slide guide to be set at the wrong point.
To prevent wrong positioning of the slide guide, the DADF comes with two types of slide guide positioning members; when fitted correctly, the positioning mem-
bers will make sure that the slide guide will stop at the correct point.

2.3.5 Detecting the Presence/Absence of an Original in the Manual Feeder

The presence/absence of an original in the manual feeder is detected using the manual set sensor (PI12).
When an original is placed in the manual feeder, the original pushes the sensor flag, causing the sensor flag to reach the sensor, enabling the DADF to assume the
presence of an original in the manual feeder.
When the Start key is pressed, the DADF picks up the original from the manual feeder for copying.
