Document Feeding and Scanning  
This chapter describes precautions regarding documents that can be  
handled on this scanner and scanning operations.  
• 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.  
Documents  
This section describes the types of documents that can be used and  
how to place them.  
Wrinkled or creased  
Carbon backed paper  
paper  
CAUTION  
Treat the documents carefully. The paper edges may cut your  
fingers.  
Coated paper or fax  
Curled paper  
recording paper  
Document  
Torn paper  
Extremely thin paper  
The CR-190i can feed a wide variety of document sizes. The ranges  
of height and length for a document are:  
Paper with clips or  
staples  
Paper with binding holes  
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/m2)  
NOTE  
Length  
• 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.  
Height  
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  
• 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.

• Additional documents can be placed while the machine is  
scanning.  
Envelope  
You can also scan the envelope. When using separation OFF mode,  
you can scan an envelope with thickness up to 0.02" (0.5 mm) or  
weight up to 111 lb bond (413 g/m2).  
NOTE  
• Disable the double feed detection function. (See “Using Ultrasonic  
Double Feed Detection,” on p. 33 in Instructions.)  
• If the envelope is not the first document in the batch, it may cause  
a feeding error or a paper jam.  
• Some type of envelope may cause a feeding error or a paper jam.  
Placing Documents  
Note the following points when placing documents on the scanner.  
• Place the front of the document toward you.  
• Do not exceed the Load Limit Mark when placing documents in  
the document tray. This may cause feeding errors or paper  
jams.  
IMPORTANT  
• Align the documents and set the bottom of the documents level in  
the document tray.  
• Do not exceed the Load Limit Mark when placing documents. This  
may cause double feed error.  
Load Limit Mark  
• A maximum of 250 documents can be loaded at one time.  
• Move the stopper to the edge of the document in the document  
tray in accordance with the document. Otherwise, this may  
cause a paper eject error.

If the documents are not aligned, press the JOG Button.  
The jogger mechanism can be used to align documents.  
This section describes how to load and scan documents.  
CAUTION  
• Avoid wearing loose fitting clothing, dangling jewelry, long ties,  
or long hair that could become entangled with moving parts,  
especially the rollers that feed paper through the scanner. If  
such objects become entangled, immediately disconnect the  
power plug from the power outlet.  
• Check the paper stack and remove all clips, staples, pins, or  
any other type of metal or plastic fastener. These objects may  
cause damage to the document, a paper jam, or a scanner  
malfunction.  
• Do not touch anything except the operation buttons when the  
jogger is operating or documents are being fed.  
• Do not touch documents that are being fed under any  
circumstances. The documents that are being fed may cut your  
hand.  
IMPORTANT  
• If you press the JOG Button when a batch of documents of various  
sizes are loaded, the alignment will be incomplete, and the  
documents will not be scanned in the order loaded. If you are  
scanning documents of various sizes, align the leading edges of all  
the documents with the entry point of feeding.  
Scan Procedure  
• The jogger mechanism is not available for documents of less than  
5.9" (150 mm) in length.

following conditions:  
• The STOP Button is pressed and the scanning stops.  
• There are documents on the document tray when a paper jam  
occurs.  
Remove the documents from the document tray to close the shutter.  
If the jammed document remains or the Top Cover is removed, the  
jogger does not work.  
• The jogger vibrates for 6 seconds, and then stops. Press the JOG  
Button to stop the jogger.
