USB Host

The USB host port allows you to connect USB devices—such as a keyboard, scanner, or USB flash (memory) drive—to the printer.
Uses for the USB Host are as follows:
  • Firmware updates
  • File transfers and management
  • A port for low power USB data entry devices (keyboards, scales, scanners, and other wedge devices).

The USB Flash drive must be formatted using the FAT file system. Filenames can be 1 to 16 alphanumeric characters (A, a, B, b, C, c, ..., 0, 1, 2, 3, ...) only. Use only ASCII characters. Do NOT use Asian characters, Cyrillic characters, or accented characters in filenames. Some functions may not work properly if there are underscores in a filename. Use periods instead.
