Mandrels not aligned with coupling: If the mandrels are not properly aligned with the coupling, the ribbon will not be pulled through the printer smoothly, causing the dreadful ribbon break error.

Removing the side plates allows you to peak into the unit to see which mandrel is not properly aligning with its motor coupling.

Cassette posts bent: Bent cassette posts can cause the ribbon to snag and break during printing. It can also cause the cassette to bind on assembly making in assembly process difficult. Generally when this happens the mandrels can also be affected causing there alignment to be off. Inspect the cassette posts and replace them if necessary.


Cores slipping on mandrels: If the cores slip on the mandrels, the ribbon tension will be compromised. The slippage occurs when the ribbon core internal diameter does is not secured by the mandrels. Sometimes this is because the mandrel clips are not engaging the cores and other times it is just a defect of the cores. Make sure the cores are securely fastened to the mandrels.

Friction cones are cracked: Cracked or worn friction cones can cause ribbon slippage, resulting in breaks. Inspect the friction cones and replace them if necessary.
