If the ribbon is breaking, the most likely cause is wrong timing of the Print Signal from your host packaging machine. Please refer to this article for more help on how to check the Print Signal timing.
If you have checked the print signal timing and are sure it is correct, but the ribbon is still breaking, then we recommend you use the Marsh 241D App Troubleshooting utility.
If you still require help, please contact our support specialists - you can do this via the Chat facility from the Home Page or Product Page, or via the Contact Us form.
