Abstract
A cartridge using an endless printer ribbon includes a re-inker and a drive assembly which pulls the ribbon through the re-inker and advances it while folding it in fan fold fashion into a storage compartment. The fan folds are compressed before they exit from the storage compartment into an expansion area where the fan folds unfold. From the expansion chamber the ribbon passes through a straightening compartment to ensure that all the folds in the ribbon have been eliminated before the ribbon leaves the cartridge.
