96 Chapter 9 Troubleshooting the Copier/Scanner

Scanned image is of poor quality

Is the original a second generation photo or picture?

Reprinted photographs, such as in newspapers or magazines, are

printed using tiny dots of ink that make an interpretation of the original

photograph; thus, the quality is dramatically decreased. Often, the ink

dots form unwanted patterns that, when scanned and reprinted or

displayed, can be detected. If the following suggestions do not

provide a solution, you may need to use a better-quality version of the

original.

●

Try to eliminate the patterns by reducing the scanned image size.

See “Enhancing the scanned image.”

●

Print the scanned image to see if the quality is better. See below.

●

Try recalibrating the scanner. See “Calibrating the scanner.”

●

Verify your resolution and gray-scale settings are correct for the

type of scan job you are performing. See “Scanner resolution and

gray scale.”

Is the image quality better when printed?

The image displayed on screen is not always an accurate

representation of the quality of the scan.

●

Try adjusting the settings on your PC monitor to display more

colors (or levels of gray). Typically, this is adjusted by selecting

“Display” found in the Control Panel. See the documentation that

came with your PC.

●

Try adjusting the resolution and gray-scale settings in the scanner

software. To learn more about these settings, see “Scanner

resolution and gray scale.”

Is the image skewed (crooked)?

The original may have been loaded incorrectly. It is important to use

the paper guides when loading originals. See “Loading Copier/

Scanner originals.”

Does the scanned image have unwanted blots, lines, vertical

white stripes, or any other defect?

See “Improving scan/copy quality.”

Is the scanner dirty?

If the scanner is dirty, the image produced will not have optimum

clarity. See “Cleaning the scanner.”

Do graphics appear different from the original?

The graphics settings may not be suitable for the type of scan job you

are performing. Try changing the graphics settings. Access these

settings through the printer properties (driver). See “Printer properties

(driver).”
