The cost of replacement consumables and parts depends entirely on the brand and specification of the bits and pieces that you want. Generally speaking, higher yield toners will cost more money than those with a lesser capacity. However, in the long-term, consumers tend to find that these are much more cost-effective. When it comes to replacement parts, prices will vary subject to the machine that you own. Manufacturers all retail their replacement parts at different prices, so it can be useful to research these costs before buying your machine. This will give you a good idea of which brands offer greatest value for money.
