When a ribbon cartridge is removed from a machine such as a typewriter or printer, for example, a compressible roller binds a ribbon against a wall of the cartridge to prevent the ribbon from moving. This prevents ribbon breakage during the next usage of the ribbon due to looping of the ribbon over the take up spool, for example. During use, the material of the roller compresses allowing the roller to turn and thus less tendency for the ribbon to move up and down the roller to also reduce ribbon breakage.
