OpisPL<> NazwaEN<> OpisEN<> UwagiBiuromax<> The differences of the drums in new and old RICOH 3003 model: The new RICOH 3003 drumbushings and drum drive end are designed differently. Old: No gear on the drum end. The drum is driven by a long steel rod which is installed inside the drum. There is no slide bearing inside the bushing. New: Agearis added on the drum driveendto coordinate with the bushing and drive the drum. Aslide bearing is inside the bushing. New: On the driven end, a change was made to allow for a bushing to help drive the drum. On the drive end, a new gear has been added to eliminate the need for the long steel drive rod. Old: Both the drive and driven ends were designed to coordinate with the long steel drive rod. How customer can check which type of opc is inside drum unit? -> Have to check the drum unit itself, but it seems can not be recognized from the out looking of the drum unit itself. What the difference is between the old and new drum unit, it is only on the drum gear. For old one: There is a metal roller(shaft) in the opc drum. One end of the metal roller is same with the new drum gear (longer one). For new one: There is no metal roller inside the opc. When fixed drum, it can be fixed easily.
