ADF Open

When scanning is performed with the ADF open, the following error code appears on the LCD of the scanner's operator panel.

ADF Open

HINT

If you open the ADF while the scanner is ready, only an error message will appear without an error code.

Also, note that the buttons on the operator panel are disabled while the ADF is open.

Confirm that the ADF is closed properly.

To check whether or not it is closed completely, open the ADF and then close it again.

For more details about opening and closing the ADF, refer to Opening/Closing the ADF.
