Ive got the store down the street from me swearing up and down that they are having a good result from pulling the cap on the TN-210's and dumping the old toner and then just dumping in the new bottle of toner from SCC (they say no vacuuming or blowing at all, just dumping it out and tapping the cartridge a little bit). Is it even possible that this could work correctly? I cant bring myself to do it, but i am just wondering if there is even an outside chance that they could be getting a good result from this? Would like other peoples thoughts and to know if anybody else has ever tried this, I need to know what i am up against competition wise.
