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 Adobe Photoshop LE, 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.

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 back of the scanner. Align the original’s corner with the alignment mark.

Alignment Mark

Close the cover carefully so the original does not shift out of position.

Caution

• Be careful not to dirty the document glass when placing items on it.

•If an original has distinct horizontal or vertical lines, you should try to position it on the document glass as squarely as possible to have the lines appear straight.

•The maximum scanable size is the area of the entire document glass.

•Straighten out curls or folds in originals before placing them on the document glass.

•To scan right to the edges of an item, position it approximately 3 mm away from the edges of the document glass (platen).

16

S T E P 1

Previewing

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.

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%
6"/15cm	8"/20cm
Scanning with horizontal/
vertical 2x magnification
4"/10cm
Scanning at 50%	3"/7.5cm
Scanning with horizontal/	2"/5cm
vertical 0.5x magnification

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

Scanning Resolution

Magnification changed to

50% 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.

		Image size = 5"x5"				Image size = 2.5"x2.5"
		(12.7 x 12.7cm)					(6.35 x 6.35cm)
Magnification
50%
	Scanned at				Output device
	360 dpi					corrects to

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	Click inside these boxes
magnification factor to 100%.	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.

				408MB
			102MB
A4 color image
		25.5MB
1.6MB	6.3MB
75dpi	150dpi	300dpi	600dpi	1200dpi

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

20

S T E P 1

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.

8 bit Grayscale

Expresses a dot in up to 256 shades of gray. Select this option for scanning black and white graphics and photographs.

Grayscale (14/16 bit)

Scans the image with finer tonal gradations. Select it when a particularly high-quality image is required. Grayscale (14 bit) (16,384 shades between black and white) can be selected with the CanoScan D1230U, and Grayscale (16 bit) (65,536 shades between black and white) with the CanoScan D2400U. The data obtained with this setting can only be used with Photoshop LE and certain other applications.

24 bit Color

Expresses a dot with 8 bits or 256 shades for each primary color - red, green and blue (RGB) - for a total of 24 bits. A dot can be expressed in up to 16.7 million distinct shades. Use this option for most color photographs.

Color (42/48 bit)

Scans the image with finer color gradations. Select it when a particularly highquality image is required. Color (42 bit) (16,384 colors per RGB channel) can be selected with the CanoScan D1230U, and Color (48 bit) (65,536 colors per RGB channel) with the CanoScan D2400U. The data obtained with this setting can only be used with Photoshop LE and certain other applications.

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 or 2GB, the scan button is unavailable.

21

S T E P 1

Operating Procedures

Click the arrow beside Scan Mode.

Selecting the box opens the pop-up menu.

Select a scan mode from the pop-up menu.

Caution

• If you select 14/16 bit Grayscale or 42/48 bit Color for a software application that does not support these options, the system may hang up when you attempt to execute the scanning job with either selection. Before you use these settings, check the specifications to determine whether or not 14/16 bit Grayscale and 42/48 bit Color scanning is supported. Adobe Photoshop (Ver. 3.0 or later) and Adobe Photoshop LE supplied with this package support these modes.

•If you scan an image with a version of Adobe Photoshop compatible with 42 bit Color, a 14/16 bit Grayscale or 42/48 bit Color image is scanned as a 16-bit Channel Mode image.

•14/16 bit Grayscale and 42/48 bit Color images generally cannot be printed without modification. To print them out, first transform them into 8-bit Grayscale or 24-bit Color images, respectively.
