2. Documents The scanner can scan documents ranging in size from business cards and checks to 11" × 17"/A3 size. The size and type of paper that can be fed depends on the feeding method. Acceptable Documents The scanner can feed the following document sizes. Size Width: 2" to 12.01" (50.8 mm to 305 mm) Length: 2.76" to 17.01" (70 mm to 432 mm) (without using the Long Document Mode) 2.76" to 39.37" (70 mm to 1m) (using [ON1] in the Long Document Mode) 2.76" to 118.11" (70 mm to 3m) (using [ON2] in the Long Document Mode) Hint When the Long Document Mode is selected, Paper Size Detection can be used for scanning documents up to 118.11" (3 m) long. (See "Long Document Mode Setting" on p. 16.) Paper Thickness Continuous Feeding: 14 to 56 lb bond (52 g/m2 to 209 g/m2) (0.06 mm to 0.25 mm) Manual Feeding: 11 lb to 64 lb bond (42 g/m2 to 255 g/m2) (0.05 mm to 0.30 mm) Hint • Continuous feeding feeds document pages one after another by the feed and retard rollers after placing a batch of documents in the Document Feed Tray. • Manual feeding requires feeding one document at a time while the [Separation Off] key on the control panel is lit and the Document Feed Tray is raised. 2 Basic Operation Separation Off Key IMPORTANT A document must meet the following criteria to be scannable: • When scanning a multipage document, pages must be grouped together so that they have the same size, thickness, and weight. Scanning different types of paper at one time can cause the scanner to jam. • Always make sure that the ink on a document is dry before scanning it. Scanning documents with the ink still wet may soil the rollers or scanning glass, cause lines or smudges to appear on images, or dirty other documents. • Always clean the rollers or scanning glass after scanning a document written in pencil. Scanning documents with pencil written on them may soil the rollers or scanning glass, cause stripes to appear in images, or dirty other documents. • When scanning a two-sided document that is printed on thin paper, the image on the opposite side of each page may show through. Adjust the scanning brightness from the application program, or enable the [Prevent Bleed Through/Remove Background] setting before scanning. 15
