(2) Activating the continuous operation test
Open the ADF and close it again. If no document is loaded on the ADF within five sec-
onds after closing the ADF, the image scanner runs in flatbed mode. If documents are
loaded on the ADF within five seconds after closing the ADF, the image scanner continu-
ously feeds the document from ADF. Once the image scanner start reading documents in
the flatbed mode, it does not feed documents from ADF even if documents are loaded on
the ADF.
(3) Ending the test in flatbed mode
To stop the carrier movement in flatbed mode, open the ADF cover. If the ADF cover is
opened, the POWER lamp starts blinking immediately after the carrier returns to the home
position.
(4) Ending the test in ADF mode
If the ADF document hopper is empty, feeding documents from the ADF ends. To restart
feeding, open the ADF cover and close it again. Then load documents on the ADF docu-
ment hopper within five seconds after closing the ADF cover.
(5) LED status on error
If an error occurs during the test, the LED indicates as shown in table B.1.
If paper is jammed in the ADF, remove the jam and close the ADF cover. The CHECK
lamp stops blinking about three seconds after closing the ADF cover. To feed the docu-
ment from ADF, open and close the ADF cover.
