Multifeed detection checks for overlapping documents, the length of documents, or both. The following conditions must be met to avoid triggering multifeed detection:

• ADS-4300N/ADS-4700W

  • All pages in the document loaded in the ADF must be the same weight.

    Paper weight must be between 11 lb and 53 lb (between 40 g/㎡ and 200 g/㎡).

  • The 3.15 in. (80 mm) area in the center of the document must be free of perforations or holes, and must have no other documents attached to it.
  • The document must be placed in the center of the Pick Up Roller.
  • All pages in the document must be wider than 3.15 in. (80 mm).
• ADS-4900W

  • All pages in the document loaded in the ADF must be the same weight.

    Paper weight must be between 9 lb and 110 lb (between 35 g/㎡ and 413 g/㎡).

  • The 1.77 in. (45 mm) area in the center of the document must be free of perforations or holes, and must have no other documents attached to it.
  • The document must be placed in the center of the Pick Up Roller.

• Scanning thick documents such as plastic cards may incorrectly result in multifeed errors. If this happens, disable multifeed detection.
• A multifeed cannot be detected when the machine is set to (Manual Single Mode).
• If the document paper are too thin or the width of the documents is too narrow, the sensor may not be able to detect a multifeed.
