Using Infrared Double Feed Detection The double feed detection function that the scanner is equipped with uses the infrared sensor to detect when two or more documents are fed at the same time. If false detections happen too often, disable the double feed detection function. NOTE • When Using the Accompanying Scanning Utility for CR-50/80/L1 (or CR50&80&L1): You can disable the double feed detection function from [Scanner Setting] in the Scanning Utility. • For more details about how to configure scanning parameters, click the [Help] button in the settings dialog box to view the Canon driver help. IMPORTANT • The following types of document may be misdetected as double fed: • Documents with a colored background • Documents with a glossy finish If misdetection of double feeds occurs often, turn off double feed detection. Placing Documents Note the following points when placing documents on the scanner. • Place the front of the document toward you. • A maximum of 50 documents (90g/m2 (24 lb bond)) or a document stack no higher than 5 mm (0.2") can be loaded at one time (including curling). • Move the stopper to the edge of the document in the document tray in accordance with the document. Otherwise, this may cause a paper eject error. • When scanning multiple documents, sort them into batches of uniform paper quality and thickness and load each batch separately. Note that loading mixed batches may cause paper jams. • When scanning relatively thick (0.15 mm to 0.2 mm (0.005" to 0.008") documents, the feeding process may cause the document to curl and cause paper jams at the document feed opening. For such documents, load no more than 10 sheets at one time. IMPORTANT Align the documents and set the bottom of the documents level in the document tray. Document Feeding and Scanning This section describes how to load and scan documents. CAUTION • Avoid wearing loose fitting clothing, dangling jewelry, long ties, or long hair that could become entangled with moving parts, especially the rollers that feed paper through the scanner. If such objects become entangled, immediately disconnect the power plug from the power outlet. • Check the paper stack and remove all clips, staples, pins, or any other type of metal or plastic fastener. These objects may cause damage to the document, a paper jam, or a scanner malfunction. • Do not touch documents that are being fed under any circumstances. The documents that are being fed may cut your hand. Scan Procedure A Pull out the document feed tray. B Carefully align the edges of the document. C Load the documents with their front sides facing right and with their edges flush against the document load mark. Document Load Mark 23
