No, it’s not mandatory to use the manufacturer’s cartridges. On 17th June 2005, the Royal Mail and the Office of Fair Trading (OFT) made a significant ruling. They declared it illegal for franking machine suppliers to force customers into buying cartridges directly from them under the threat of invalidating warranties. Additionally, manufacturers are not allowed to include their ink in their maintenance contracts. This must be a separate agreement, providing customers with the option to opt in or out as they choose. This means you have the freedom to choose compatible cartridges, like our Postbase Qi3/Qi4/Qi6/Qi9 compatible ink, without worrying about affecting your franking machine’s warranty. Our cartridges offer a high-quality, cost-effective alternative while ensuring full compliance with your machine’s warranty and Royal Mail regulations.
