bi-tonal output.
Image quality features • Adaptive Threshold Processing (ATP), image compression, despeckle, and
dithering for bi-tonal scanning
• Built-in iThresholding for bi-tonal scanning uses a single setting to produce
the highest quality images for mixed document sets of varying quality (i.e.,
faint text, shaded backgrounds, color backgrounds).
• Image capture optical resolution: 300 dpi
• Image output resolution: 75/100/150/200/240/300/400/600 dpi for bi-tonal,
grayscale, and color scanning
NOTE: Throughput speed at 400 dpi and 600 dpi is dependent upon your
PC configuration.
• Auto-color balancing (auto-white balancing) to ensure good color balance
after calibration
• Pixel and color correction for the best color image quality
• Five levels of JPEG compression allow images to be viewed in many
