| Cartridges aren't usually noisy. The average one-piece cartridge contains toner, possibly some stirrer paddles, developer, doctor-blade, pre-charge roller, drum, scraper blade and probably a waste toner receptacle. In other word its a set of rollers driven by cogs down the side. It isn't easy to turn the parts of a cartridge because the scraper blade in particular puts quite a lot of pressure on the drim, but it should be possible (watch out for blotches of toner on clothes) It is not unknown for a cartridge to not turn. Refurbs are often to blame, the cartridge has been badly reassembled. It isn't impossible with a brand new cartridge that has been stored badly, the scraper blade might stick to the drum for instance. |
