Chapter 4 Using the Scanner Documents This section describes the various types of documents that can be scanned with the feeder. Handle documents with care. Improper handling of paper can cause paper cuts or other CAUTION personal injury. Types of Documents The following are the dimensions of the documents that can be fed by the feeder: Width: 55" to 12" (139.7 mm to 304.8 mm) Length: 5" to 17" (128 mm to 432 mm) (Normal Mode) 5" to 24" (128 mm to 630 mm) (Long Document Mode) 5" to 21" (128 mm to 540 mm) (Long Document Mode/Color 600 dpi Mode) Document Thickness Black-and-white Documents Simplex: 0.002" to 0.006"/0.06 mm to 0.15 mm Duplex: 0.002" to 0.006"/0.07 mm to 0.15 mm Black-and-white/Color Documents Mixed: 0.002" to 0.006"/0.07 mm to 0.15 mm Color Documents 0.003" to 0.006"/0.08 mm to 0.15 mm Document Weight Black-and-white Documents Simplex: 11 to 32 lb bond/42 to 128 g/m2 Duplex: 13 to 32 lb bond/50 to 128 g/m2 Black-and-white/Color Documents Mixed 13 to 32 lb bond/50 to 128 g/m2 Color Documents 17 to 32 lb bond/64 to 128 g/m2 Follow these guidelines when you prepare a document for scanning: • When scanning long documents, turn the Long Document Mode "ON" in the user mode. (See "About the User Modes," on p. 70) • Before scanning documents that contain pasted artwork, make sure that the ink or paste on the pages is thoroughly dry. If the documents are scanned with the ink or paste still wet, the scanner may malfunction. • If you scan a document written in pencil, the letters may not scan 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 Feeder," on p. 94.) • If you scan thin paper in the Duplex mode, the ink printed on the back side may be scanned. In this case, adjust the scanning density. 46
