33 Document Feeding and Scanning This chapter describes precautions regarding documents that can be handled on this scanner and scanning operations. This section describes the types of documents that can be used and how to place them. CAUTION Treat the documents carefully. The paper edges may cut your fingers. DocumentThe CR-50/80 can feed a wide variety of document sizes. The ranges of height and length for a document are: Height : 50 to 108 mm (2.0 to 4.3) Length : 80 to 228 mm (3.1 to 9.0) Thickness : 0.08 to 0.20 mm (0.003 to 0.008) 0.10 to 0.14 mm (0.004 to 0.006) with Double Feed Detection enabled Weight : 64 to 157 g/m 2 (17 to 40 lb bond) 81 to 105 g/m2 (21.5 to 26.8 lb bond) with Double Feed Detection enabledFollow these guidelines when you prepare a document for scanning: Before scanning documents that contain pasted artwork, make sure that the ink or paste is thoroughly dry. If the documents are scanned with wet ink or paste, the inside of the scanner may become dirty and it may cause a malfunction. If you scan a document written in pencil, the letters may not be scanned properly or the pencil may rub off onto the rollers and stain subsequent documents. Before you scan this kind of document, make a copy, and then scan the copy. After scanning a document written in pencil or some other soft writing material, be sure to clean the scanning rollers. (See “Cleaning the Scanning Glass and Rollers,” on p. 45.) If you scan thin paper in the Duplex mode, the ink printed on the back side may be scanned. If this happens, adjust the scanning density. Scanning documents with a rough surface may not feed easily, and may cause friction between the documents, resulting in a feeding error. If this happens, feed the documents one by one. To avoid paper jams, damage to documents, and a scanner malfunction, do not feed the following types of paper into the scanner. If you want to scan these types of paper, first make a copy, and then scan the copy. Documents Length Height
34 NOTE Note that mixing documents of different thickness may cause a malfunction during feeding. Curled, wrinkled, or folded documents may cause an error. If this happens, straighten out the curls, or reduce the number of documents loaded. 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: 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. Double feed detection is valid for documents with a thickness within the range 0.10 mm to 0.14 mm (0.004 to 0.006). Double feeds cannot be detected for thicker or thinner documents. Wrinkled or creased paperCarbon backed paper Curled paper Torn paper Paper with clips or staplesCoated paper or fax recording paper Extremely thin paper Paper with binding holes
35 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 or a document stack no higher than 5 mm (0.2) can be loaded at one time. 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. 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. Document Feeding and Scanning
36 Scan Procedure APull out the document feed tray. BCarefully align the edges of the document. CLoad the documents with their front sides facing right and with their edges flush against the document load mark. DAdjust the Eject Stopper in accordance with the document. EInstruct scanning to start from the software application. NOTE When Using the Accompanying Scanning Utility for CR-50/80: There are three scanning methods as follows. Follow the each instruction. Scan 1 page Click [Scan Page] from the [File] menu. Scan Batch to File AClick [Scan Batch to File] from the [File] menu. BInput the File name, and then click [Save]. CSelect Simplex or Duplex, and then click [Start Scanning]. Scan Batch to Printer AClick [Scan Batch to Printer] from the [File] menu. BSelect Simplex or Duplex, and then click [Start Scanning]. Document Load Mark
37 FScanning starts. NOTE When printing with the imprinter, ink may get on the leading edge of the document because the documents are ejected onto the printed surface. Confirming Proper Document Feeding Depending on the thickness of documents scanned with the CR-50/80 and the paper thickness setting, double feeds or feeding errors may occur. After installing the CR-50/80 or before scanning documents of a different thickness, perform the procedure below to confirm that documents are separated one sheet at a time. If documents do not feed properly, see “Adjusting the Separation Roller Gap,” on p. 52 to adjust for paper thickness. AStart the Scanning Utility. Ink residue Printed text (back side)
38 NOTE For instructions on using the scanning utility, see “How to Use the Scanning Utility,” on p. 28. You can also refer to the scanning utility help in the [Help] menu. BPull out the document feed tray. CLoad two documents with their edges flush against the mark. DAdjust the position of the eject stopper. (If necessary, see the diagram in step 4 on p. 36.) EClick [Scan Page] from the [File] menu and confirm that only one sheet is fed. Document Load Mark
39 NOTE If the sheets do not feed properly (they double-feed or no sheets are fed), see “Adjusting the Separation Roller Gap,” on p. 52 to adjust for paper thickness. FExit the scanning utility.
40 Troubleshooting This chapter describes the problems that might occur in the CR-50/80, and how to remedy them. The following causes and remedies describe why your computer may not recognize the scanner.If paper has jammed, open the Maintenance Cover and remove the jammed paper. IMPORTANT Do not attempt to pull the jammed paper upwards or backwards against the feeding direction. Doing so can damage the internal parts of the scanner. CAUTION Be careful when you clear a paper jam. You may be injured unexpectedly. For example, the paper edges may cut your fingers, or the document may be damaged. Remove all jammed sheets of paper. Paper scraps left inside the scanner may cause a paper jam or malfunction. AHook your finger around the open lever and open the Maintenance Cover. When the Scanner Is Not Recognized Cause The Scanning Utility is not installed. Remedy Install the Scanning Utility before connecting the scanner to the computer. (See “Setting Up the Scanner,” on p. 17.) Cause The scanner is not correctly connected to the computer. Remedy Connect the scanner to the computer correctly. (See “Connecting the Scanner to a Computer,” on p. 21.) Cause The USB interface provided as standard with your computer is not compatible with the scanner. Remedy Not all USB interfaces provided as standard with personal computers are guaranteed. Contact your local authorized Canon dealer for more detailed information. (See “Checking Your Operating Environment,” on p. 18.) Cause USB cable is not compatible with the scanner. Remedy Use the USB cable provided with the scanner. (See “Checking Your Operating Environment,” on p. 18.) Cause USB hub is not compatible with the scanner. Remedy Remove the USB hub to use the scanner.
