Document Feeding and Scanning
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.
CAUTION
Treat the documents carefully. The paper edges may cut your 
fingers.
DocumentThe 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/m
2 (17 to 40 lb bond)
81 to 105 g/m2 (21.5 to 26.8 lb bond) with Double Feed 
Detection enabledFollow 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.

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.
Using Infrared Double Feed Detection
The double feed detection function that the scanner is equipped with 
uses the infrared sensor to detect when two or more documents are fed 
at the same time.
If false detections happen too often, disable the double feed detection 
function.
NOTE
When Using the Accompanying Scanning Utility for CR-50/80:
You can disable the double feed detection function from [Scanner 
Setting] in the Scanning Utility.
For more details about how to configure scanning parameters, click the 
[Help] button in the settings dialog box to view the Canon driver help.
IMPORTANT
The following types of document may be misdetected as double fed:
Documents with a colored background
Documents with a glossy finish 
If misdetection of double feeds occurs often, turn off double feed 
detection.
Double feed detection is valid for documents with a thickness within the 
range 0.10 mm to 0.14 mm (0.004 to 0.006). Double feeds cannot be 
detected for thicker or thinner documents.

Placing Documents
Note the following points when placing documents on the scanner.
 Place the front of the document toward you.
 A maximum of 50 documents or a document stack no higher than 
5 mm (0.2) 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.
 When scanning multiple documents, sort them into batches of 
uniform paper quality and thickness and load each batch 
separately. Note that loading mixed batches may cause paper 
jams.
 When scanning relatively thick (0.15 mm to 0.2 mm (0.005 to 
0.008) documents, the feeding process may cause the 
document to curl and cause paper jams at the document feed 
opening. For such documents, load no more than 10 sheets at 
one time.
IMPORTANT
Align the documents and set the bottom of the documents level in the 
document tray.
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 documents that are being fed under any 
circumstances. The documents that are being fed may cut your 
hand.

Scan Procedure
APull out the document feed tray.
BCarefully align the edges of the document.
CLoad the documents with their front sides facing right and with 
their edges flush against the document load mark.
DAdjust the Eject Stopper in accordance with the document.
EInstruct scanning to start from the software application.

FScanning starts.
NOTE
When printing with the imprinter, ink may get on the leading edge of the 
document because the documents are ejected onto the printed surface.
Confirming Proper Document Feeding
Depending on the thickness of documents scanned with the CR-50/80 
and the paper thickness setting, double feeds or feeding errors may 
occur.
After installing the CR-50/80 or before scanning documents of a 
different thickness, perform the procedure below to confirm that 
documents are separated one sheet at a time. If documents do not 
feed properly, see “Adjusting the Separation Roller Gap,” on p. 52 to 
adjust for paper thickness.
AStart the Scanning Utility.

Troubleshooting
This chapter describes the problems that might occur in the CR-50/80, 
and how to remedy them.
The following causes and remedies describe why your computer may 
not recognize the scanner.If paper has jammed, open the Maintenance Cover and remove the 
jammed paper.
IMPORTANT
Do not attempt to pull the jammed paper upwards or backwards against the 
feeding direction. Doing so can damage the internal parts of the scanner.
CAUTION
Be careful when you clear a paper jam. You may be injured 
unexpectedly. For example, the paper edges may cut your fingers, or 
the document may be damaged.
Remove all jammed sheets of paper. Paper scraps left inside the 
scanner may cause a paper jam or malfunction.
AHook your finger around the open lever and open the 
Maintenance Cover.
