VENTING PLUG IN TONER CARTRIDGE |
摘要 |
Hopper plug (143) vents out air pressure build-up which cause toner leaks. One side of the plug has a series of entrance openings (491) which communicate with the inside of the hopper (61). Air, potentially containing some toner particles, passes through those openings and enters a first chamber (507). The first chamber has exit holes (499) which do not face the entrance openings. Air passing through the exit holes of the first chamber enters a second chamber (509). The second chamber has exit holes (495) which are at the opposite end and do not face the entrance openings. Third chamber (511) of this labyrinth faces a mat toner filter (501) which leads to exit holes (503). |
