[. . . ] Flatbed-- Use this setting if you are using the flatbed to scan one page at a time. 6-1 6. 2 DETERMINING THE RESOLUTION Good control of the resolution results in satisfactory detail of a scanned image. Normally, the greater the dpi number, the higher the resolution and the larger the image file size. Be aware that greater resolution takes more time, memory, and disk space; therefore, up to a certain degree of dpi, the resolution will not visually be improved. On the contrary, it makes your files more unmanageable. Resolution: 50 dpi Resolution: 100 dpi 6-2 - Tips: 1. For your information, an A4-size color image scanned at 300 dpi at True Color mode consumes approximately 25 MB of disk space. A higher resolution (over 600 dpi) is recommended only when you need to scan a small area at True Color mode. You can also refer to the following table to choose a proper resolution for your image. Image Type Scanner Settings Application File, Fax, E-mail Your Document View, Copy, Edit Your Color Picture OCR* Your Document Resolution (dpi) 200 100 300 LineArt True Color LineArt *OCR: Stands for Optical Character Recognition, the process of converting an image to a text format. 6-3 6. 3 SELECTING THE PROPER IMAGE TYPE Select the appropriate image type from the scanner user interface for your specific document. The following image types are available: Line art (Black and White) LineArt presents the image in black and white only, and there are no intermediate shades of gray in between. LineArt is the best choice of image type if you want to scan text or a pen or ink drawing. Since only 1 bit of black or white information is required for each pixel*, the disk space required for saving LineArt images is only about 1/24 of that required to save 24-bit true color images. LineArt Image *Pixel: A combination of two words: picture and element. A pixel is a single dot on a computer display or in a digital image. 6-4 - Halftone Halftone simulates grayscale by using different size dots. Particularly when you view the image at a certain distance, it looks very much like a grayscale image, yet it consumes less disk space. The pictures that we usually see in newspapers or magazines are halftones. Since Halftone is one type of black and white image, the disk space required to save a halftone image is 1/24 of that required to save a 24-bit true color image. Halftone Image 6-5 8-Bit Gray A single-channel image consists of at least 256 shades of gray. An 8-bit scanner produces a grayscale image with 1024 shades of gray between pure black and pure white. With 8 bits of color information per pixel, the file size of an image is eight times larger than a Black and White image and 1/3 the size of a 24-Bit Color image. Gray Image 6-6 - 8-Bit Color A 8-Bit Color image provides 256 color hues in the image. The file size of a 256 color image is 1/3 the size of a 24-Bit Color image. 8-Bit Color Image 24-Bit Color A 24-Bit Color image consists of three 8-bit color channels. The red, green, and blue channels are mixed together to create a combination of one billion colors which give a more true-to-life quality to the image. Choose 24-Bit Color if you are scanning color photos. 24-Bit Color Image 6-7 6. 4 BRIGHTNESS Click on the Brightness button to adjust the lightness or darkness of an image. Decrease your brightness Normal Increase your brightness 6-8 - 6. 5 CONTRAST Click on the Contrast button to adjust the range between the darkest and the lightest shades in the image. Decrease your contrast Normal Increase your Contrast 6-9 6. 6 INVERT IMAGE Click on the Invert Image button to reverse the brightness and color in the image. For color images, each pixel will be changed into its complementary color. [. . . ] 2) Use the Brightness setting of the TWAIN user interface to get a brighter image. It is suggested that you add a second printer card for printing, or you may call your authorized local dealer for further support. Answer: Disable the Auto Scan function in the application, and then your printer will function normally. 9-1 Question: Why do not some parallel port devices work with the SC-215?Answer: The SC-215 does support pass-through printing, but the pass-through printing may not work if you connect the parallel port with devices other than printer.
