Changing the drum unit
First get into service mode. Utility/Counter then meter count then check details. Then Stop 00 stop 01. Counters. Clear Drum and Developer. Then touch end do not exit all the way out of service mode. Turn off the machine using the main on/off rear of machine left hand side. Then remove the image cart. and replace the drum and developer. then turn machine on reenter service mode. Run F-8 found under Function. Do not print copy or allow fax to print before this is done. Or you will have to replace the developer again. So remove network cable and fax line if machine is as printer and FAX. after powering off

This is a service technician performed function. The PC Drum unit is changed by removing the whole imaging unit and then removing the drum section and changing it out. At the same time the developer needs to be cleaned from the developing unit and replaced with fresh developer. The drum counter is then reset using the service mode and then the new developer must be calibrated using the F8 mode. So in this machine's case, this is just not a pull out the old unit and plug in a new one.
If you find the "right" service guy, he can come in and reset the drum counter and do the f8 without changing either the drum or the developer. This can sometimes get twice the life out of the unit. Copy quality can degrade a bit towards the end of the second cycle.
If you just reset it your looking at around $100. If you do everything that is called for then the cost is more like $350.
Good Luck and Thank You for using Fixya.
