Document Feeding and Scanning This chapter describes precautions regarding documents that can be handled on this scanner and scanning operations. Documents 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. Document The 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/m2 (17 to 40 lb bond) 81 to 105 g/m2 (21.5 to 26.8 lb bond) with Double Feed Detection enabled Length Follow 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. Height 33

Follow 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,
