Specifications are subject to change without notice.

  1. Optical resolution is a measure of maximum hardware sampling resolution, based on ISO 14473 standard.
  2. Increasing the scanning resolution will limit the maximum possible scanning area.
  3. Pre-processing time is not included.
  4. Connecting the bundled USB cable to the port corresponding to USB3.0 and above on PC. Colour document scan speed: (Colour A4, 300dpi) is measured with ISO/IEC  29183 Target-A.  Colour photo scan speed: 10.15 x 15.24cm (4x6in, 300dpi) is measured with ISO//JIS SCID No.2.  Scan speed indicates the time measured between pressing the scan button of the scanner driver and the on-screen status display turns off.  Scan speed may vary depending on system configuration, interface, software, scan mode settings and document size etc.
  5. The fastest speed in Hi-Speed USB on Windows PC.  Transfer time to computer is not included.
