Before Using Adobe Acrobat 9.0
There are two methods for scanning a document from the scanner 
using the bundled Adobe Acrobat 9.0 software. One method is 
Presets (Black & White Document, Grayscale Document, Color 
Document, or Color Image), in which the scanning parameters are set 
beforehand. The other method is Custom Scan, which allows you to 
select the parameters used for scanning. The Custom Scan method 
also provides the option of either showing or hiding the scanner’s 
Native Interface (the machine’s own scanner settings screen) while 
scanning.

If you use Adobe Acrobat 9.0 with this machine and scan using the 
Custom Scan method, you should display the scanner’s Native 
Interface because you will not be able to scan correctly on the 
specified paper size.
Procedure for Showing the Native Interface in Custom 
Scan
1Click [Create], and then select [PDF from Scanner] - 
[Custom Scan].
2Click [Options] in the Custom Scan dialog box to open the 
Scanner Options dialog box.
3From the [User Interface] drop-down list, select [Show

the dialog box.
The scanner runs the Custom Scan, and the Native Interface (the 
machine’s own scanner settings screen) is displayed.

Scanner Operation Settings
You can specify the wait time before the scanner enters the sleep 
mode and specify whether to turn the scanner ON and OFF 
automatically when the computer is turned ON and OFF.
To configure these settings , open the Scanner Properties screen.
Opening the Scanner Properties Screen
The instructions shown are when you are using the Windows Vista 
operating system.
1Click [Start], [All Programs], and [Canon DR-2020U], then 
click [Utility].
Canon imageFORMULA Utility starts.
2Select [CANON DR-2020U USB], and then click 
[Properties].
Hint
 If the scanner does not appear in  the list, check that the scanner 
is turned ON and connected to the computer, and then click 
[Update].
 In Windows Vista, the [User Account Control] screen appears.  If you are logged on as an administrator, click [OK]. If you are 
not logged on as an administrator, enter the password of a user 
that has administrator privileges, and then click [OK].

Scanner Property Settings
This section describes the setting items in the [CCFL Control] and 
[Power Control] tabs.
Hint
The [Event] tab is a standard tab in the operating system. For details 
on this tab, refer to the operation manual or Help for your operating 
system.
[CCFL Control]
Specify the wait time before the scanner enters the sleep mode.
When the scanner is not operated for the amount of time specified 
here, it automatically enters t he sleep mode, and the scanner lights 
turn OFF.
The scanner exits the sleep mode when you perform scanning 
operations from the computer, or when you press any button on the 
operation panel.
Hint
The DR-2020U uses CCFL (Cold Cathode Fluorescent Lamps). The 
brightness of the lamp must be adjusted before scanning operations 
begin. As a result, scanning may not immediately start in situations where the 
lamp brightness has not been adjusted, such as immediately after 
turning ON the scanner or immediately after the scanner exits the 
sleep mode. In such cases, the following message appears on the 
computer display until the lamp brightness is adjusted. Warm up may 
take up to 30 seconds.
When the lamp brightness adjusts, scanning begins automatically.
[Power Control]
Specify whether to link the scanner’s power to your computer so that 
the scanner turns ON and OFF when your computer turns ON and 
OFF.
If [The scanner turns on in conjunction with the PC] is selected, the 
scanner automatically turns ON or OF

Maintenance
Routine Cleaning
Clean the scanner on a regular basis to maintain scanning 
performance.
WARNING
 For safety, always turn the power switch OFF and disconnect the  power cord before cleaning the scanner and the inside of the 
feeder.
 Do not use spray-type cleaners to clean the scanner. Precision  mechanisms may get wet and malfunction.
 Never use paint thinner, alcohol,  or other solvents to clean the 
scanner. Doing so may deform, discolor, or dissolve surfaces, or 
result in a fire or electric shock.
Cleaning the Scanner
Use a cloth dampened with water and thoroughly wrung out to clean 
the outside of the scanner, and use a clean dry cloth to wipe the 
scanner dry.
Cleaning the Feed Path
Dust or paper particles in the document  feed inlet or inside the feeder 
can cause spots to appear in scanned images. Use compressed air to 
periodically clean dust and paper particles from the inlet and inside the 
feeder. In particular, be sure to turn the scanner OFF, and remove the 
dust and paper particles after scanni ng a large volume of documents.
Cleaning the Scanning Glass and 
Pressure Board
If streaks appear in scanned images, or if scanned documents 
become dirty, the scanning glass and pressure board may be dirty. Be 
sure to clean them regularly.
1Open the feeder gently, and use a clean, dry cloth to wipe 
the scanning glass and pressure board clean.
