Power Supply
●Connect only to a power outlet of 
the rated voltage and power supply 
frequency (either 120 V, 60 Hz or 
220-240 V, 50/60 Hz, depending on 
your region).
● Do not connect other electrical 
equipment to the same power outlet 
to which the scanner is connected. 
Also, when using an extension 
cord, make sure that the extension 
cord is rated for the current 
requirements of the scanner.
● Never attempt to dismantle or 
modify the AC adapter in any way, 
as doing so is dangerous.
● Do not place objects on or step on 
the AC adapter or power cord.
● Do not use the power cord while it is 
coiled.
●Do not pull directly on the power 
cord. When disconnecting the 
power cord, grasp the power plug 
and remove it from the power outlet.
● Keep the area around the power 
plug clear of objects so that the 
power cord can be disconnected 
easily in an emergency.
● Use only the AC adapter supplied 
with the scanner. In addition, do not 
use the supplied AC adapter with 
devices other than the scanner.
● If you have any questions regarding 
the power supply, contact your local 
authorized Canon dealer or service 
representative for further 
information.

Features
Multiple Methods for Document Feeding
●Scan multipage documents at up to 20 pages per minute (for single-
sided documents) using the built-in feeder. The scanner can detect 
documents that are loaded into the feeder and begin scanning 
automatically using the auto-start function.
● Use the flatbed to scan documents that cannot be scanned through 
the feeder (thin documents, documents that do not feed smoothly, 
magazines and thicker documents, etc.).
● Feed and scan up to 15 business cards at a time using the built-in 
business card feeder.
Easy Scanning with Job Functions
Start scan procedures using the  buttons on the operation panel 
without having to open an application program.
Wide Range of Black and White and Full 
Color Scanning
● Scan documents in 24-bit color or 256-level grayscale.
● Scanning in black-and-white (binary) is also possible. Use the 
advanced text enhancement modes to clarify text when scanning 
documents with dark backgrounds or faint text.
● Use the color smoothing mode to reduce the occurrence of moiré 
patterns when scanning color images from a magazine, for

document and pauses so that you can use the first image to adjust the 
brightness and contrast before scanning resumes.
Energy Efficient Design
This scanner conforms to inter national Energy Star program 
standards, and enters a sleep mode when it is not scanning.
Variety of Image Processing Options
● Auto Paper Size Detection
Detect the document page size while scanning. This also removes 
the blank space that surrounds an image when a document of a 
non-standard size is scanned.
● Text Orientation Recognition
Detect the text orientation on each document page, and rotate the 
scanned image in 90-degree increm ents as necessary for 
normalization. (This function may not work properly depending on 
the document type.)
● Deskew
Detect whether a document has been fed askew image, and 
straighten the image as necessary.

Handling Documents
Feeding Methods
There are three feeding methods (feeder, flatbed, business card feeder) for scanning documents with this scanner. The types of  documents that 
can be scanned with each method are as follows.
Precautions for Using the Feeder
 When scanning a multipage document in a single scan procedure  using the feeder, make sure that all of the pages are identical in 
thickness, and quality of paper. Feeding different types of paper at 
one time may cause a paper jam.
 Scanning documents before the ink  is dry will make the rollers and 
scanning glass dirty, resulting in smears on the scanned image and 
other documents becoming dirty. Always make sure that the ink on 
a document is dry before scanning it.  Scanning documents that 
are written in pencil or similar material will 
make the rollers and scanning glass dirty, resulting in smears on the 
scanned image.
 When scanning thin paper, text or images on the reverse side of the 
page may bleed through onto the scanned image. In this case, 
adjust the brightness under the scanning conditions.
 Always make sure to check that paper clips, staples, and similar 
objects are not mixed in with a document before loading it into the 
feeder. The presence of such objects may result in damage to 
documents, paper jams, and damage to the scanner.
