It looks like the toner cartridge has leaked: there are heavy black bands on every printout, and it seems that there is toner on the drum as well. This is disappointing: we have only had the printer a few months and are still using the cartridge that came with it. Does anyone have an pointers to documentation about how to clean the printer out? I have looked in the documentation, but haven't found anything. Would any of this be covered under warranty? If not, this is the least economical printer on the planet. The supplies are all showing 99%, but replacing the toner and drum would be more than half what we paid for the printer.
