Replacing the Developing Unit
The developing unit has a life-span of approx. 25,000 copies.
When the life of the developing unit is near the end, code [P29]
displays in the Print quantity/Magnification ratio window to let you
know that approximately 500 additional copies can be made before
the copier shuts down.
When the life of the developing unit is actually over, code [P29]
displays and further coping will not be possible. When code [P29]
appears, replace the developing unit as shown below.
If necessary, contact your Konica service representative for supplies.
