These functions are controlled by the commands from your scanner software. EPSON Expression 636 Function Available settings Output resolution 30 settings from 50 to 2400 dpi (hardware) 31 settings from 50 to 4800 dpi (software) 1 Reading seauence 1 One or three oass scannina I I Zoom 50% to 200% in 1% increments Data format 1 to 8 bits per pixel per color Captures up to 12 bits/pixel/color. When it captures over 8 bits, it converts the information to 8 bits/pixel/color.

You may want to experiment with your scanner settings, possibly using a cropped version of your image to save time, until you achieve the desired results. The resolution that you use to scan an image (input resolution) does not have to match the dots per inch of your printer (output resolution). Input and output resolution are two quite different measurements.

The data format can be set in the range of 1 bit to 8 bits per pixel per color. As the value increases, more tones and colors can be captured in the scanned image as shown in the following table: Data format 1 bit/pixel/color 2 bits/pixel/color 3 bits/pixel/color 4 bits/pixel/color 5 bitS/DiXel/COlOr 6 bits/pixel/color 7 bits/pixel/color 8 bits/pixel/color 1 Monochrome 1 2 grays 4 grays 8 grays 16 grays , 32 -ar,avs I64 grays 1 128 grays I256 grays 1 Color 1 8 colors 64 colors 512 colors 4,096 colors 32.768 colors 1262,144 colors I2,097,152 colors 16,777,216 colors Scanners 9130196 EPSON Expression 636-3
