The function to protect documents (Paper protection) prevents documents from being damaged during scanning with the ADF by increasing the level of sensitivity to detect paper jams.

Take the following measures.

• If this error occurs, check if the document meets the requirements described in Documents for Scanning.

• If this error occurs frequently even when the document meets the requirements for scanning, lower the paper protection sensitivity level.

• If documents remain in the ADF, remove the documents by referring to When a Paper Jam Occurs.
