This self-extracting file contains the Epson Twain 2.11e driver for the ES-300C (SCSI only), ES-600C, ES-800C, ES-1000C, and ES-1200C image scanners. This driver is compatible with Windows 3.1, Windows NT 3.11, and Windows NT 3.5. This version offers improved compatibility with non-Adaptec SCSI hardware. After extracting the files in a temporary subdirectory, install the Twain driver by running Setup from Run in the Windows File menu. Note: This driver does not support the ES-300C bidirectional interface. Windows NT requires the use of SCSI hardware.
