Experience the same reliable performance without the high cost. We've taken a toner cartridge that's been made by Xerox for a different sales channel and modified the code so that it can be used in a standard VersaLink C400/C405 . We do this because we understand the importance of using Genuine Toner Inside. While other "compatible" brands may be cheaper, you run the risk of putting unknown and potentially detrimental toner formulations into your machine.
