Segmented ink reservoir

An ink reservoir (34) capable of maintaining an even distribution of a single color of ink on a printer ribbon is provided. The ink reservoir is used in ribbon cassettes (10) for typewriters and dot matrix printers. The ink reservoir (34) includes a series of cylindrical ink-carrying elements (50) separated by a series of separating sheets (52). The separating sheets (52) restrict or prevent the flow of ink from one ink-carrying element to another element. This maintains an even distribution of ink throughout the height of the reservoir which, in turn, results in an even transfer of ink from the ink reservoir onto a transfer roller and subsequently onto a ribbon. The even distribution of ink in the ribbon results in an even distribution of ink in the characters printed using the ribbon and, thus, improves print quality.
