Important Note for Installation of the New Drum
Since the smoothness of the new drum (without dichloromethane) is reduced, it is
essential to make sure to apply Drum Setting Powder (P/N: 54429101) to the drum
surface as shown below before installing.
Note:
If the setting powder is not applied, the drum’s cleaning blade may turn outward,
causing a drum cleaning failure.
Application Procedure for Drum Setting Powder
1. Apply the setting powder (P/N 54429101) to the drum by tapping the powder bag across
the surface area shown in the illustration below, i.e. spanning the entire length of the drum
but covering about a 45-90 degree portion (up to 1/4) of the total surface.
Note:
! Be sure to apply enough powder to give the area a moderate dusting (so that the
area turns white).
! If setting powder is not available, please apply waste toner in the same manner
described above (waste toner is charged and will be attracted to the drum surface).
Please note that although dirty background will have a greater tendency to occur,
be sure to apply the waste toner if there is no setting powder available.
2. Install the new drum in the OPC unit so that the powdered area (in bold below) faces the
cleaning blade.
3. Rotate the drum once in its normal rotation direction (arrow shown below), so that it
stops again at the same position.
Note: Be sure not to rotate the drum in the opposite direction.
