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-L1 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 : 95 to 228 mm (3.7" to 9.0")
up to 2,000 mm (78.7") with Long Document mode
Thickness : 0.08 to 0.20 mm (0.003" to 0.008")
2
Weight : 64 to 157 g/m (17 to 40 lb bond)
2
81 to 105 g/m (21.5 to 26.8 lb bond) with Double Feed Detection
enabled
NOTE
Depending on the paper type and paper thickness, false detection of double
feed may occur.
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. 32.)
• 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.
Length
Height
• 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.
Wrinkled or creased
paper
Curled paper
Torn paper
Paper with clips or
staples
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.
