Improving fax recognition
Try these solutions to improve OCR accuracy on fax images:
Ask senders to use clean, original documents if possible.
Ask senders to select Fine or Best mode when they send you a fax. This produces a resolution of 200 x 200 dpi.
Ask senders to transmit files directly to your computer via fax modem if you both have one. You can save fax images as image files and then load them into OmniPage. See Loading image files for more information.
