Specify the number of feeding retries when a document is not fed from the ADF paper chute (feeder).

Paper Feeding Retries

The factory default setting is "4".

Multifeed is an error that occurs when two or more sheets are overlapped and fed at once.

Configure the settings to detect overlapped documents during a scan.

Overlapped documents are detected with the ultrasonic sensor or according to the difference in length of the documents.

When overlapped documents are detected, an error message is displayed and the scan stops. If documents are overlapped within 30 mm from the leading edge, they are not detected as overlapped.

Detection Method

Specify a method to detect overlapped documents.

• Does not detect

  Does not detect overlapped documents.

  This is the factory default setting.

• Check Overlapping (Ultrasonic)

  Detects overlapped documents with the ultrasonic sensor.

  When this is selected, you can specify the following two options:

  • Specify an area to detect overlapped documents by the length from the leading edge of the document in the feeding direction.

    Set it in [Multifeed Detection Area].

  • When a piece of paper is attached on a document, the length and position of the paper can be memorized, and set to ignore overlapping of documents.

    For details, refer to Configuring Not to Detect Certain Overlap Patterns.

• Check Length

  Detects overlapped documents according to the difference in length.

  Select this to scan documents of the same length.

  ATTENTION

  Note that overlapped documents cannot be detected accurately when a mixed batch of different lengths are scanned.

• Check Overlapping and Length

  Detects overlapped documents by the combination of [Check Overlapping (Ultrasonic)] and [Check Length].

  When this is selected, you can specify the following two options:

  • Specify an area to detect overlapped documents by the length from the leading edge of the document in the feeding direction.

    Set it in [Multifeed Detection Area].

  • When a piece of paper is attached on a document, the length and position of the paper can be memorized, and set to ignore overlapping of documents.

    For details, refer to Configuring Not to Detect Certain Overlap Patterns.

  ATTENTION

  Note that overlapped documents cannot be detected accurately when a mixed batch of different lengths are scanned.

Threshold (Length)

Specify this item when [Check Length] or [Check Overlapping and Length] is selected for [Detection Method].

Specify the difference in length of documents to be detected as overlapped documents.

Overlapped documents are detected when the difference in length of documents is longer than the specified value.

Any length under the specified value is tolerated as a slight error and not detected as overlapped documents.

• 10 mm or less is not detected

  This is the factory default setting.

• 15 mm or less is not detected

• 20 mm or less is not detected

Specify an area to detect overlapped documents.

Specify this item when [Check Overlapping (Ultrasonic)] or [Check Overlapping and Length] is selected for [Multifeed Detection].

Enable

Specify whether to set an area to detect overlapped documents.

The factory default setting is set to off.

How to set the detection area

Specify whether to set a disabled area or enabled area to detect overlapped documents.

• Set the disabled area

  This is the factory default setting.

• Set the enabled area

Start (mm)

Specify the start position of the detection area by the length from the leading edge of the document in the feeding direction.

Range: 0 to 510 mm, in 2 mm increments, Start ≦ End

The factory default setting is "0".

End (mm)

Specify the end position of the detection area by the length from the leading edge of the document in the feeding direction.

Range: 0 to 510 mm, in 2 mm increments, Start ≦ End

The factory default setting is "0".

Configure the setting to automatically ignore certain patterns of overlapped documents when the setting to detect overlapped documents is enabled.

Note that you first need to specify [Check Overlapping (Ultrasonic)] or [Check Length] in the scanner driver and "Multifeed Detection Area" on the touch screen before setting this item.

For details about the settings on the touch screen, refer to Configuring Not to Detect Certain Overlap Patterns.

Operation mode

Set the operation mode.

Manually Bypass

Specify whether overlapped documents are detected when re-scanning documents detected as overlapped documents.

Does not memorize the size or location of the paper attachment.

Scanning will stop immediately if overlapped documents are detected.

Note that if the settings for the scanner driver are configured to stop the scan to check images, scanning will stop after detected overlapped documents are scanned to the bottom edge.

This is the factory default setting.

Automatically Bypass (combination of length and position)

Specify whether the length and position of a piece of paper attached on a document detected as overlapped documents are memorized as an overlap pattern.

If the overlap pattern is memorized, documents with the same overlap pattern are not detected as overlapped documents from the next scan.

Scanning will stop after the detected overlapped documents are scanned to the bottom edge.

Overlap patterns can be memorized for up to 32 sheets (up to four overlap patterns can be memorized per sheet scanned).

Once overlap patterns have been memorized for 32 sheets, the memorized patterns will be overwritten by any newly detected patterns starting from the first sheet that was memorized.

However, when the scanner is turned off and on, the number of memorized overlap patterns depends on the setting for [When powering off] of [Memorize overlap pattern].

Automatically Bypass (length)

Specify whether the length of the longest piece of paper attached on a document detected as overlapped documents is memorized as an overlap pattern.

If the overlap pattern is memorized, a document with a piece of paper in the same length or shorter attached is not detected as overlapped documents from the next scan.

Scanning will stop after the detected overlapped documents are scanned to the bottom edge.

Only one overlap pattern can be memorized in this operation mode.

Memorize overlap pattern

When confirming image

When [Automatically Bypass (combination of length and position)] or [Automatically Bypass (length)] is selected, you can manually switch whether or not to memorize an overlap pattern on the touch screen when overlapped documents are detected.

Select the default setting for the above function.

The factory default setting is set to off.

The overlap pattern is memorized when the [Scan] button on the scanner is pressed for the next scan.

For details about the function that memorizes an overlap pattern, refer to Configuring Not to Detect Certain Overlap Patterns.

When powering off

Specify whether or not to keep overlap patterns upon turning the power off.

When this is set to on, eight of the most recent overlap patterns for [Automatically Bypass (combination of length and position)] and one overlap pattern for [Automatically Bypass (length)] can be used the next time the scanner is powered on.

The factory default setting is set to off.

Overlap pattern

[Clear] button

Press this to erase the overlap patterns that were memorized in the scanner.

Delete all the overlap patterns that have been memorized in the scanner.

You can erase overlap patterns that were not supposed to be memorized, but be careful with this operation because all memorized patterns will be erased.

Configure the settings when manually loading and scanning one sheet at a time.

When you scan by manually loading one sheet at a time, you can specify the waiting time (interval) for loading the next document in the ADF paper chute (feeder). This enables continuous scanning as long as you load a document within the specified time.

If the specified time is exceeded, the scan is finished automatically.

Continuous Feed Mode

Set whether to enable the Manual Continuous Mode.

Set [Continuous Feed Mode] to on to scan more than one document in succession manually.

The factory default setting is set to off.

When Manual Single Mode is used, the setting for [Continuous Feed Mode] is ignored.

Manual Feed Mode

Set this item when you use Manual Single Mode to scan documents by manually loading one document at a time in succession.

Do not continue

Clears Manual Single Mode after a scan is complete.

This is the factory default setting.

Continue

Does not clear Manual Single Mode until the [Manual - Single] button is pressed on the touch screen.

Timeout seconds

Specify the time period until which the scanner confirms that no documents are loaded in the ADF paper chute (feeder) (the interval between the last scan and the detection of whether the next document is loaded or not).

The factory default setting is "10".

Enable this mode to use the scanner at an altitude of 2,000 m or higher.

Low atmospheric pressure at high altitudes may lower the accuracy in detections for overlapped documents with the ultrasonic sensor.

Enable

Setting [Enable] to on for this item improves the accuracy to detect overlapped documents.

The factory default setting is set to off.
