ABSTRACT:
A printer ribbon cartridge (10) containing an internal re-inking mechanism (12) for re-inking the ribbon (14) housed in the cartridge is provided. The internal re-inking mechanism (12) comprises a drive assembly (30), pump (24), an eccentric (26), an ink reservoir (22), an ink feeding tube (34), a re-inking ring (30) and a transfer roller (38). As the ribbon (14) is threaded and propelled through the drive assembly (30), the drive assembly drives the pump (24) via the eccentric (26). The pump (24) pumps ink from the ink reservoir (22) to the re-inking ring (36) through the ink feeding tube (34). The ink is transferred from the re-inking ring (36) to the ribbon (14) via the transfer roller (38).
