6. Turn OFF the main power and unplug the power cord from the wall outlet.
7. Replace the PM parts and turn the main power ON.
The machine will reset the PM counters automatically. In the case of the development unit,
developer initialization will also be done automatically.
8. Exit the SP mode.
After Installing the New PM Parts
1. Output the SMC logging data with SP5-990-004 and check the counter values.
Make sure to shut down and reboot the machine once before printing the SMC. Otherwise, the
latest settings may not be collected when the SMC is printed.
2. Make sure that the PM counters for the replaced units are "0" with SP7-621, or SP7-944.
If the PM counter for a unit was not reset, then execute the new unit detect setting with
SP3-701 again and turn the machine OFF/ON.
3. Make sure that the exchange counter counts up with SP7-853.
4. Make sure that the counters for the previous units (SP7-908) on the new SMC logging
data list (from step 2 above) are equal to the counters (SP7-621, or SP7-944) for these
units on the previous SMC logging data list (the list that was output in the "Before
removing the old parts" section).
5. Make sure that the unit replacement date is updated with SP7-950.
