Maximum document size A4 or US letter size

(8.5 × 11.7 inches [216 × 297 mm]) Up to legal size if using the optional auto document feeder (The reading area can be specified from

software.) Optical resolution 600 dpi Maximum hardware

resolution* 600 dpi (main scan) × 2400 dpi

(sub scan)**

* The maximum hardware resolution of 600 × 2400 dpi is achieved

using EPSON’s Micro Step

** The maximum hardware resolution for sub scans is 2400 dpi when

the width of the document to be scanned does not exceed 4 inches. If the width exceeds 4 inches, the scanning software interpolates the resolution after 1200 dpi.
