Frequently Asked Questions - CanoScan D660U CANON

How do I connect the CanoScan D660U to my computer?

Use the provided USB cable to connect the scanner to a USB port on your computer. Ensure the scanner is powered on via the AC adapter. Windows and Mac OS should detect it automatically; install drivers from the included CD if needed.

What should I do if the scanner is not recognized?

First, check the USB connection and try a different port. Restart your computer. If the issue persists, reinstall the scanner drivers from the CD or download the latest from Canon's support website.

Can I scan slides or negatives with this scanner?

The CanoScan D660U can scan film using the optional transparency unit. Without it, only reflective documents (photos, paper) can be scanned.

What is the maximum scan resolution?

The optical resolution is 1200 x 2400 dpi. Software interpolation can achieve higher resolutions, but optical quality is best at 1200 dpi.

How do I clean the scanner glass?

Turn off the scanner and unplug it. Use a soft, lint-free cloth slightly dampened with water or a mild glass cleaner. Wipe the glass gently and dry immediately. Avoid abrasive materials.

Does the scanner work with Windows 10?

Official drivers were released for Windows up to XP. For Windows 10, try using Windows Update or third-party scanning software like VueScan which supports many older scanners.

Why are my scanned images blurry?

Ensure the document is placed flat against the glass. Increase resolution and check focus settings in your scanning software. Also, clean the glass if dusty.

How long does it take to scan one page?

At 300 dpi color, a full A4 page takes approximately 12 seconds. Higher resolutions or larger scans will take longer.

Can I scan multiple pages into one PDF?

Yes, using scanning software that supports multi-page PDF. For example, Canon ScanGear or third-party tools like Adobe Acrobat can combine scans into a single PDF file.

Where can I find the user manual?

The user manual is available for free download on notice-facile.com or the Canon support website. It contains detailed instructions for setup, operation, and troubleshooting.

Welcome to ScanGear CS-U

Welcome to Canon ScanGear CS-U 5.8 software for Windows 98 and Windows 2000 Professional.

ScanGear CS-U 5.8 (hereafter referred to as ScanGear CS-U) will provide flexible, efficient image enhancement tools for scanning with your CanoScan D660U Scanner by providing an interface with a variety of TWAIN-compliant software applications. (TWAIN p.101)

ScanGear CS-U has a number of powerful features that help you achieve peak performance with your scanner. Using ScanGear CS-U, you can preview and adjust an image before the image is scanned and acquired by the parent software application.

Here is a quick summary of the important features of ScanGear CS-U:

• Two operation modes: Simple mode, which allows you to select all optimum settings with one selection, and Advanced mode, which allows you to create professional color and other enhancements for artistic effects.
• Flexible, fully automatic image acquisition, and pre-scan image manipulation prior to passing data to the image application
• TWAIN 1.6 compliant
  • Text Enhanced mode for OCR applications
• Canon ColorGear (color matching software technology)
  • Automatic preview or preview image cache
• ScanGear CS-U can run with or without its main window, depending on the acquiring application.
• 35 mm film can be scanned using the film adapter unit attached to the scanner.

Normally when you start a scanning job, you will see the ScanGear CS-U main window with its toolbar, Preview Area, and tabs.

However, some software applications may not open the ScanGear CS-U main window. When this occurs you cannot use the settings described in this user's guide because the host software application will provide the settings so you can change the image after it is acquired. When a software application uses ScanGear CS-U without opening the ScanGear CS-U main window, this is called the windowless mode.

Gamma Sheet

When the Gamma button is clicked, the Gamma sheet is displayed.

Gamma refers to a process where mid-tones are shifted so that the lighter colors are lightened and darker colors are darkened. For example, let us say you scanned a photograph of a subject in a boat in a tree-lined lake and the shadows of the trees are dark enough and the white of the boat is light enough, but the blue in the sky, the blue of the water, and the blue of the subject's clothing all look the same. By increasing the Scanner Gamma value of the image, the sky might become lighter and the water darker, giving a better contrast to the image. The Monitor Gamma value is a reciprocal number of the Scanner Gamma value.

Channel

If you want to select one of the primary colors (RGB) for adjusting the gamma value, click the Channel down-arrow and select the color or leave the settings at Master to adjust all the colors.

Entering a value into either boxes of the scanner gamma or the monitor gamma will display a respective value in the other box. The allowed range of values are 0.10 to 10.00, inclusive. The shape of the tone curve changes to reflect the current gamma setting for the current Channel, and the image in the Preview Area changes to reflect the adjustment. When the Scanner Gamma value is modified, the Monitor Gamma value changes automatically.

Histogram Sheet

When the Histogram button is clicked, the Histogram sheet is displayed.

Use the histogram to enhance an image when the image is either too light or too dark, like an overexposed or underexposed photograph. Increasing the darker tones with the histogram improves the contrast of the image.

Channel

If you want to select one of the primary colors (RGB) for adjusting the histogram, click the Channel down-arrow and select the color, or leave the setting at Master to adjust all colors.

Here are some hints for editing curves:

• Curve handles are drawn on a white background as a red dot to signify that they are editable. When the cursor is over the handle, it changes to a crosshair.
• Curve end points can be selected and dragged to any point in the curve but cannot be deleted.
• Up to 15 points can be added to a curve by clicking anywhere in the curve box.
• If you drag a point outside of a curve box, it will be deleted from the curve and a new curve will form with the remaining points.
• The x and y axes on the curve chart represent the input image color and output image color. When you add a handle to the curve and drag that handle toward the white areas, the preview image tones are adjusted to reflect the change.
• More than one handle cannot be positioned on a vertical line but more than one handle can be positioned on a horizontal line so you can have several handles on a horizontal line.

Pre-Scan Checklist

Perform the checks on this short list before you begin troubleshooting specific problems.

• Make sure that the ScanGear CS-U software was installed successfully.
• Confirm that the cables between your computer and scanner are connected securely.
• Before scanning or previewing, check that the data source has been selected. If your scanner does not appear as an option when you select a TWAIN source to scan from your imaging software, you have to install ScanGear CS-U again. (p.12)

How to Avoid Problems

Here is some general advice on avoiding problems in your scanning jobs:

• Start with the best possible original image to scan.
• Select only the part of the image you want to scan. Preview the image and select it with the Crop and Auto Crop buttons. Not only does a more precise selection save file space, but your image quality will be much higher.
• Check the output file size before beginning the scan. Make sure you have enough room if you are scanning files that require a large amount of disk space.
• Match your Color Mode to the output purpose. If you are scanning text, use the Text Enhanced mode. If you are scanning line art, use the Black and White setting, and so on.
• Match your scan resolution to the type of file you need. If you are scanning images for use as .GIF or .JPG files on the Web, you do not have to scan at 600 dpi. Although it is recommended that you scan at a higher resolution than you need for high-quality color images, you should balance that factor against your planned use for the image.
• Take advantage of the Tone sheet features to enhance your images. (p.41)
• Try to use TrueColor mode on your monitor so you can view your preview image as accurately as possible.

Troubleshooting Checklist

The scanner diagnostics test fails.

Problem: The Scanner Diagnostics test, started with the Test Scanner button on the Scanner sheet, returns a Test Failed message.

Cause: The scanning unit may not be in its home position.

Solution: Close the ScanGear CS-U window if it is open. Try turning the scanner off and back on again by unplugging and plugging in the USB cable. Then restart your computer.

Colors not what you expect.

Problem: The colors in the preview image appear different from the colors in the original image.

Cause1: The scanned colors need to be adjusted.

Solution: Make sure the Auto Tone button is selected. If further adjustments are necessary, use the Tone sheet buttons.

Cause2: The calibration slot on the film guide is obstructed.

Solution: Clear the item blocking the calibration slot.

The preview image of a photograph appears blurred but the scanned image of the same photograph appears sharp.

Problem: When zooming in on a photograph in the Preview area, the enlarged image appears blurred.

Cause: The preview scan uses a lower resolution than the final scan. If you zoom in on a preview image so it is enlarged, the image will not maintain its resolution in the same way as the final scanned image.

Solution: Select a magnified area and preview the image again. The scan should display a sharper image.

Solution: Check that Canon ColorGear Color Matching is selected on the Preferences sheet.

Cause3: The settings of the printer driver, such as color balance or Gamma, do not match to the printer.

Solution1: Adjust the color balance in the printer driver manually.

Solution2: Change the Gamma value setting of the printer driver.

The software application cannot find the scanner.

Problem: When trying to scan, an error message says the scanner cannot be found.

Cause: Windows may not recognize your scanner.

Solution: Make sure the scanner is connected to your computer before you turned on the computer and started Windows. If not, connect the scanner. Then restart your computer. If this does not correct the problem, consult the scanner user manual for additional information about how to properly set up your scanner.

Some buttons are grayed-out.

Problem: Buttons in the Toolbar are grayed-out and not available.

Solution: Before scanning the image, make sure you have set the Scan Resolution on the Main tab to not exceed the resolution of your printer. Also check to see if there is enough memory available in your computer. Before scanning, quit other applications that are not in use.

Cause 2: DMA option for computer's hard disk drive is not turned on.

Solution: Windows 98: Turn on the DMA option in the System Properties dialog as described below.

Right-click the [My Computer] icon on the Windows desktop, select [Properties] from the pop-up menu and click the [Device Manager] tab in the System Properties dialog. In the [Disk Drives] category, select the appropriate hard disk and click the [Properties] button on the Device Manager tab. Click the [Settings] tab and place a check in the [DMA] option. Restart the computer. (Please consult the manufacturer of your computer for confirmation that the DMA function is supported.)

Windows 2000: Turn on the DMA option. The procedures are similar to those for Windows 98 with a few variations.

Glossary

Contents

Index

Parts of images are missing or not aligned.

Problem: Some characters are missing from the image in the Preview Area, or the image is not aligned in the Preview Area.

Cause: The page has been placed on the scanner improperly.

Solution: Check the scanner and place the original correctly to adjust the image.

Image is too light or too dark compared to the original.

Problem: Scanned or printed image is much lighter or darker than the original.

Cause: Image and color adjustments may not have been set properly.

Solution: The best solution is to scan the image using all default settings again. Then make imaging and color adjustments as necessary.

The preview image is too small on the monitor

Problem: The image in the Preview Area is very small, and cannot be viewed in the Preview Area for adjustment.

Cause: If you have a high-resolution setting on your monitor, the ScanGear CS-U window is smaller than if you had a lower-resolution setting.

Solution: Drag the Window Resize Corner (p.26) on the lower right of the ScanGear CS-U window to enlarge the entire window or lower your monitor's resolution with the Control Panel.

Acquired Images

Images sent from your scanner software to the host graphics application.

Auto Crop

After you select an area of the screen by clicking the Crop button and dragging a rectangle around the object or text you want to crop, click the Auto Crop button to size the rectangle exactly to the size of the object or block of text enclosed in the rectangle.

Auto Tone Adjustment

Automatic analysis and adjustment of the image using Contrast/Brightness and Gamma settings.

Automatic Preview

When the automatic preview feature is switched on, the original on the scanner is pre-scanned immediately as ScanGear CS-U is launched from the parent software application. To switch this feature on and off, open the Preferences sheet for your scanner and click the button for "Automatically execute a preview". (p.78)

Bits and Bit Depth

A bit (Binary digit) is the smallest possible unit of information on a computer; it represents yes or no; on or off; 1 or 0. Bit Depth is used to describe the complexity of a graphic image.

One-bit, or bi-level, images are black and white. This is the Black and White setting in ScanGear CS-U. Eight-bit grayscale uses 256 shades of gray to accurately represent most black and white photographs or gray interpretations of color images. This is the

Grayscale setting in ScanGear CS-U. Twenty-four-bit color, also called True Color, uses three eight-bit channels, one channel each for Red, Green and Blue, to create up to 16.7 million colors. This is the Color setting in ScanGear CS-U.

Black-point

The darkest portion of an image scanned as Color or Grayscale. When you click on the image with the Black-point eyedropper, all tones darker than the selected sample tones are adjusted to black.

Brightness

The overall amount of lightness or darkness in an image. An image with maximum brightness tends toward white; an image with minimum brightness tends toward black. While contrast refers to the range and number of tones in an image, brightness refers to the intensity of tones.

Calibration

Calibration refers to the adjustment of color processing for input and output devices on a computer, so that the colors match throughout the process. For example, calibration ensures that the color image scanned on a scanner matches the original image when it is displayed on the computer monitor, as well as printed on a color printer.

Canon ColorGear Color Matching

Canon's process of matching the color profile of the input device (scanner) with the color profile of the output device (monitor), to yield the most accurate color image.

Clear button

The button that removes the current image from the Preview Area.

Color Channels

The red, green, or blue components of a color image. Color images contain 8 bits per pixel each for red, green, and blue channels, therefore each pixel has 24 bits. If you are scanning a color image, you can change the brightness and contrast of the individual red, green, and blue tones in your image. The Master channel is a combination of the three.

Color Matching

The range of colors your scanner can see may not match the range of colors your video monitor can produce. Color matching lets your system display colors so that the color on your monitor and printer matches the colors scanned. See also Canon ColorGear Color Matching.

Color Mode

The type of scan used to scan an image, differentiated by the number of bits per pixel. ScanGear CS-U has the following Color Modes: Color, Grayscale, Text Enhanced(OCR), and Black and White.

Contrast

Contrast refers to the difference between the lightest light and the darkest dark in the image. A low contrast value indicates that the difference between dark shades and light shades is not very great. A high value indicates a great difference between dark and light shades. While brightness refers to the intensity of tones in an image, contrast refers to the range and number of tones in an image.
