How to Use this Guide

This guide explains the operating procedures for Canon Plug-in Module CS-U (hereafter referred to as Plug-in Module CS-U), the Macintosh driver (plug-in software) used with Canon image scanners. A plug-in is not an independent software program; it must be used within a plug-in compliant application, such as CanoScan Toolbox or ArcSoft PhotoStudio 2000, to expand the capabilities of that program. Adding scanning capabilities to your computer is as easy as putting in a plug. Simply copy the Plug-in Module CS-U files to your computer. Please read this guide to perform the installation procedures and scan. Store this manual in a handy location for future reference.

S T E P 1

Caution

• Plug-in Module CS-U is not a stand-alone application program. It must be started from a plug-in compatible application program, such as CanoScan Toolbox or ArcSoft PhotoStudio 2000.

• The size of the Plug-in Module CS-U control panel will vary according to the resolution of the computer display.

• The size of the control panel can be adjusted with the [Preview Window...] option in the [Preferences] menu (p. 26).

Positioning Originals

Place the original you intend to scan on the scanner's document glass (platen).

Procedures

Place the original on the scanner's document glass.

Open the cover and set the original face down on the scanner’s document glass with the top edge at the front of the scanner. Align the original’s corner with the alignment mark.

Previewing

The preview scan is a trial scan performed before the final scan that encompasses the entire scanable area of the document glass. The preview image is shown in the preview window. Use this image to specify a scan area and adjust the scan settings for the image.

Operating Procedures

Click on the [Preview] button.

• The image will be scanned and appear in the preview window.

S T E P 1

➟

Hint

• To change the size of the preview window, use the [Window Size] settings in the Preview Window Settings dialog (p. 26).

Caution

• The Dynamic Preview function enables changes to settings, such as the scan mode and brightness, to be immediately reflected in the preview image.

• Nevertheless, the preview image provides only an approximation of the scan and the final results may differ to some degree from it.

• Calibration automatically starts when [Preview] or [Scan] button is clicked. Do not lift the document cover while calibration is in process.

When the amount of light of the lamp inside the scanner is insufficient, the message “Now adjusting lamp…” may be displayed. Wait as is, until the amount of light increases enough. If you click the [Cancel] button in this dialog, the preview scan will be executed with insufficient amount of light, and the previewed image will not have the correct color balance. Click the [Cancel] button only if you need to obtain the previewed image quickly although without the correct color balance, before the amount of light is sufficient.

Selecting the Output Device

Use the following procedures to select the output device (printer, etc.) for the scanned image. Select the device that corresponds best to your output device and use of the image.

Operating Procedures

Click the arrow on the [Output Device] section of the control panel and select a device from the pop-up menu.

S T E P 1

Caution

• You can set the device categories in the pop-up menu in advance. You can also add new devices to the pop-up menu. See Setting Preferences (p. 25).

S T E P 1

Setting the Resolution and Magnification

The magnification of an image can be changed before scanning to accommodate reproductions that are larger or smaller than the original. The settings can be changed in increments of 1%.

12"/30cm

Scanning at 200%

4"/10cm

6"/15cm

Scanning with horizontal/ vertical 2x magnification

8"/20cm

Scanning at 50%

Scanning with horizontal/ vertical 0.5x magnification

3"/7.5cm

2"/5cm

Changing the magnification setting causes the resolution display on the control panel to change correspondingly. This resolution setting is referred to as the “scanning resolution.”

Output Device Resolution= 720 dpi, Magnification= 100%

➟

Magnification

The scanning resolution changes accordingly.

Hint

Magnification and Resolution

Why does the image size change with the magnification? Let us answer this with an example using a “BJ (720 dpi)” output device. If you were to scan an image with this device setting and set the magnification factor to 50%, the scanning resolution will automatically change to 360 dpi. At this setting, the image will be scanned at a resolution of 360 dpi and the output device will convert this to 720 dpi, shrinking the size of the output in the process because it will only have half the data with which to fill the space.

Slider

Drag the slider bar in either direction or use the arrow keys to change the resolution.

Click the up or down arrow to increase or decrease the setting.

Click here to return the magnification factor to 100%.

Click inside these boxes to enter values directly.

Hint

The Relationship Between Data Volume and Scanning Resolution

The higher the magnification and scanning resolution settings, the greater the file size of scanned images. There are certain inconveniences associated with large data volumes, such as longer processing times and the risk of running out of memory resources. You are advised against setting the resolution higher than necessary. For example, if you scan an A4 (21.0 x 29.7 cm (8.3 x 11.7 in.)) size image in the color mode, the amount of data varies according to the resolution.

102MB

A4 color image

25.5MB

1.6MB

75dpi

* These numbers are approximate and may differ from actual scan results.

6.3MB

150dpi

300dpi

600dpi

408MB

1200dpi

Setting the Scan Mode

When an image is scanned, it is read as a collection of “dots.” The scan mode that is selected determines how each of these dots is represented in the output. The following four scan modes are available.

Black and White

Expresses images in two colors only: black or white. A dot is expressed as either black or white according to its brightness level and the value set as the threshold value, which can be freely set. Select this mode to output to a monochrome printer.

Grayscale

Expresses images in 256 shades of gray. Select this mode to scan black and white photographs or create monochrome images from color images.

Color

Expresses each color channel (RGB) in 256 shades (8 bit). Select this mode to scan standard color photographs.

S T E P 1

Hint

Scanning the same image in the four different scan modes produces different file sizes. By size, black and white mode requires the least disk space, followed in order by the grayscale and the color modes. Before scanning, check the data volume indicated on the control panel.

The numerator indicates the amount of disk space required for the scanned image while the denominator indicates the amount of disk space available. When the required space exceeds the available space, the scan button is unavailable.
