One of the things I love about Brother laser printers is that they appear to supply them with full toner cartridges from new whereas most laser printer manufacturers supply them with 'starter' toner cartridges that are about 1/3 full, meaning you have lash out on new toner only a few months after buying the damned things, at massive expense! The original black toner supplied with the Brother printer from new lasted 2 years and the colour toners lasted longer still!
