Chapter 4 Document Feeding and Scanning Documents This section describes the types of documents that can be used and how to place them. Treat the documents carefully. The paper edges may cut your fingers. CAUTION Types of Documents The CR-180 can feed a wide variety of Length document sizes. The ranges of width and length for a document are: Hight : 2.4" to 4.6" (60 to 118 mm) Length : 4.7" to 9.1" (120 to 230 mm) Hight Thickness : 0.003" to 0.008" (0.08 to 0.20 mm) Weight : 17 to 40 lb bond (64 to 157 g/m2) * For details on paper thickness when using infrared double feed detection function, see p.39. 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.55.) • 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. • Documents with glossy finish or colored background may cause false double feed detections when using the infrared double feed detection function. If false detections happen too often, disable the double feed detection function. (See "Using Infrared Double Feed Detection," on p.39.) • 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. 38

Document Feeding and Scanning
Documents
This section describes the types of documents that can be used and how to place
them.
Treat the documents carefully. The paper edges may cut your fingers.
Types of Documents
The CR-180 can feed a wide variety of
document sizes. The ranges of width and
length for a document are:
Hight
: 2.4" to 4.6" (60 to 118 mm)
Length
: 4.7" to 9.1" (120 to 230 mm)
Thickness :
0.003" to 0.008" (0.08 to 0.20 mm)
Weight
:
17 to 40 lb bond (64 to 157 g/m
2
)
* For details on paper thickness when using infrared double feed detection
function, see p.39.
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.55.)
•
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.
•
Documents with glossy finish or colored background may cause false double
feed detections when using the infrared double feed detection function. If false
detections happen too often, disable the double feed detection function. (See
“Using Infrared Double Feed Detection,” on p.39.)
•
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.
