Drum Unit and Development Unit
The new drum unit has a front cover and a front joint. When you attach the new drum unit to the development
unit, remove a front cover and a front joint at first.
And use them for reassembling the new drum unit and development unit.
1. If you install a new drum unit, set SP 3902-xxx to "1".
• Black: 3902-009
• Yellow: 3902-010
• Cyan: 3902-011
• Magenta: 3902-012
• If you do this, then the machine will reset the PM counter for the drum unit automatically, after
you turn the power on again.
2. Turn the machine power off.
