TROUBLESHOOTING Problem JPEG was selected for the file type but the file was created as a TIFF file. The image is too light or too dark. (When using PC Scan.) Point to check Did you press the [BLACK & WHITE START] key to begin scanning? Is the threshold value suitable? Are the brightness and contrast settings suitable? Solution When [JPEG] is selected for the file type and the image is scanned in Mono 2, the file will be created as a TIFF file. To create the file as a JPEG file, change the color mode to [Full Color] and then press the [COLOR START] key. When scanning from the TWAIN driver with [Mono 2 gradation] selected from the [Color Mode] of the "Custom Settings" window, check the "B/W Threshold" setting. A large threshold value makes the image darker and a small threshold value makes the image brighter. To adjust the "B/W Threshold" automatically, click the [Auto Threshold] button on the [Image] tab of the "Custom Settings" window. When the brightness and contrast settings are not suitable (for example, the scanned image is too bright), click the [Auto Brightness / Contrast Adjustment] button on the [Color] tab of the "Custom Settings" window. You can also click the [Brightness / Contrast] button to set the brightness and contrast while viewing the scanned image. 8-27 Contents
