Poor warranty and high priced consumables

This printer seemed pretty good at first, but the warranty does not cover "consumables". Our OPC belt cartridge (which is used to hold the image electrostatically) started to fail after 100 days, leaving streaks and smudges on the printed pages. Since it is a consumable item according to Brother, it is not covered by the warranty. The OPC belt cartridge sells for $399, which seems rather high for a consumable part on a $500 printer.
The fuser is also considered consumable. It costs more than $400. In addition, the toner cartridges cost more than $150 each.
When all is said and done, the fantastic sounding lifetime warranty covers little more than the case and power supply. We made a mistake by purchasing this printer.
