1S ship every pixel (default) 2S ship every 2nd pixel, both horizontally and vertically 3S ship every 3rd pixel, both horizontally and vertically Example of Pixel Ship set to 1S: Example of Pixel Ship set to 2S: Example of Pixel Ship set to 3S: U - Document Image Filter Allows you to input parameters to sharpen the edges and smooth the area between the edges of text in an image. This filter should be used with gamma correction (see page 8-10), with the scanner in a stand, and the image captured using the command: IMGSNP1P0L168W90%32D This filter typically provides better JPEG compression than the standard E Edge Sharpen command (see page 8-13). This filter also works well when shipping pure black and white images (1 bit per pixel). The optimal setting is 26U. 0U Document image filter off (default) 26U Apply document image filter for typical document image nU Apply document image filter using grayscale threshold n. Use lower numbers when the image contrast is lower. 1U will have a similar effect to setting E - Edge Sharpen (page 8-7) to 22e. Range: 0-255. Example of Document Image Filter set to 0U: Example of Document Image Filter set to 26U: 8 - 12
