Replacing the Ribbon

When your printing becomes too faint, you need to replace the ribbon. The Epson # 7753 standard fabric or # 7768 film replacement ribbon cartridges are recommended. See Installing the ribbon cartridge in Chapter 1.

Note:

•Use the optional film ribbon only when you need especially high quality printing. For everyday operations, use the standard ribbon.

•Do not use ribbons designed for nine-pin printers.
