In the BizHub 200-350 Series the Transfer Roller Assembly MUST be replaced at regular intervals or the bar will begin to rub on the drum and wear the coating off as well as continue into the aluminum drum itself. To avoid damage to the drum the Transfer Roller Assembly MUST be replaced. However, there is a way to double the life of each Transfer Roller Assembly before replacement. (This is also very handy if you are in the field without a new Transfer Roller Assembly but the wear on the drum is beginning to show.) This works because the drive gear holds the shaft away from the drum on the left side with the gear taking all the pressure, so the left plastic bushing receives no wear. That is why you can swap the bushings and double the life.
1. Simply open the right side door and remove the Transfer Roller Assembly by popping it out of the socket.
2. Once the gear is off the shaft, remove both the left and right bar retaining screws. (Note - there are plastic spacers which will come out from between the bar and the brackets. Keep these for reassembly.) Carefully remove the bar from both the left and right brackets.
3. Unclip the left bracket and remove. Note the direction of the plastic bushing. This will be swapped with the right side, so it will need to be flipped, keeping the larger diameter toward the foam portion of the roller. Repeat this for the right side and swap the bushings.
4. Now replace both the left and right brackets, making sure the bushings are in place with the large diameter toward the foam portion of the roller.
5. Now replace the spacers on the brackets (note there is an offset and guide tab).
6. Set the bar on the brackets and replace the screws.
7. Finally, replace the drive gear, locking clip outward, and you’re ready to reinstall the Transfer Roller Assembly into the unit for an extended life! $$$ Saved and it only takes a few minutes!
