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.

The CR-190i can feed a wide variety of document sizes. The ranges 
of height and length for a document are:

Height : 2.7" to 4.3" (68 to 108 mm)
Length : 4.7" to 9.6" (120 to 245 mm)
Thickness : 0.003" to 0.008" (0.08 to 0.20 mm)
Weight : 17 to 40 lb bond (64 to 157 g/m

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. 15.)

• 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.

• 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.
