A re-inkable ribbon cartridge for use in a printing device for printing on a sheet of paper and obtaining a consistent darkness of print. The ribbon cartridge has a base member with an exit arm and an entrance arm extending from the base member with a print space between ends of the arms. A ribbon storage chamber is formed in the base member, and an ink ribbon extends from the ribbon storage chamber and through the exit arm, the print space, and the entrance arm to return to the ribbon storage chamber. A drive wheel is mounted in the cartridge for moving the ribbon out of the storage chamber with a press wheel that presses the ribbon against the drive wheel and meters ink onto the ribbon. An ink reservoir chamber is formed in the cartridge, and a foam pad containing ink is positioned in the ink reservoir chamber. A wick extends from the foam pad and contacts the press wheel to transfer ink by capillary action from the foam pad to the press wheel which meters the ink onto the ribbon. A spring presses the wick against the press wheel.
