5) When the trailing edge of the second page passes through the ADF paper trailing edge sensor (SR719), the ADF paper sensor detects presence/absence of the
paper.
When no document is detected, the document is considered to be the last page.

6) When a specified period of time (time until the trailing edge of the document passes through the ADF delivery roller) elapses after the trailing edge of the doc-
ument passes through the ADF paper trailing edge sensor, the ADF pickup motor stops and then the ADF pickup roller moves up to a specified position.

Double-sided document reading
The procedure of reading a double-sided document is the same as that of reading a single-sided document until the step where the lead edge of the document reaches
the ADF paper trailing edge sensor. The following shows the operational sequence afterwards.
1) When the ADF paper trailing edge sensor detects the lead edge of the document, the ADF pickup motor stops and then the ADF pickup roller moves up.
When the ADF pickup roller moves up, feeding of the second and later pages stops.
As soon as receiving a drive signal from the main controller, the ADF pickup motor restarts feeding.
F-5-9
2) When the trailing edge of the document is transported until it is caught between the ADF delivery rollers, the ADF pickup motor stops.
