Pull: 100 dpi/200 dpi/300 dpi/400 dpi/600 dpi. Scanning speed. Color and B & W: 80 sheets/min. *1, 100 sheets/min. *2 *1 Speed when scanning 8-1/2 11 (A4) original in 300 dpi mode by using the ADF. *2 Speed when scanning 8-1/2 11 (A4) original in 200 dpi mode by using the Reverse Automatic Document Feeder DF-714. Single-pass dual scanning Personally, I do not perceive a significant difference between 212ppi and 300ppi, at the font settings that I like to use (somewhere around size 4 for most fonts). Here is a PW2 and PW3 side-by-side. I cropped out the identifying bottom bezel for fun, feel free to guess which is which. MaliaXOXO. Heavy-duty and flexible production scanner for professional use. The fi-7700 achieves scanning speeds of 100 ppm/200 ipm (A4 landscape, color, 200/300 dpi), is capable of loading up to 300 sheets at a time and scanning up to as many as 44,000 sheets a day. With its high quality technologies and user-friendly design, the scanner is suitable for For OCR, best scanning settings are: 300 dpi resolution for regular text, 400 dpi resolution for particularly small fonts (fine print) Black & white for text, greyscale for small fonts, color for pictures. TIFF format. Group4 is used for black & white (very small file size). If color is needed, use Uncompressed (very large file size). Meaning if you need 4x5 inches at 300 dpi, then you need a 1200x1500 pixel image (a bit more or less dpi works OK too, just scale to print size). This printing dpi number is also the scan resolution if printing at 100% or original size, but enlargement of 1.5x needs scanning at 1.5x printing dpi. The image metadata might say it's 200 ppi or 72 ppi or 1 ppi, it will still occupy exactly 200 screen dots. The world remains fixated on "72 ppi for the web," so the question of "what's the right resolution for web images" keeps coming up, and the correct answer, "it doesn't matter," keeps being supplied ad nauseam. So which print resolution is best for you? It depends on what you are printing; different industries may hold different standards for print quality. For barcodes, the difference between a 203 or 300 DPI print-out is minimal. 203 DPI is suitable if the size of the barcode is detailed enough to be reliably decoded by the intended scanner. aOsp.
