Before Replacing a Development Unit

1. Set SP3-701: New unit detection to "1" before replacing the development unit.
SPs for manual new unit
Development unit
0: new unit detection flag OFF, 1: new unit detection flag ON
2. Switch the power OFF. Then replace the development unit and switch the power ON.
• Replacing the development unit resets not only the development unit counter, but also the PCU
counter. However, if you change the SP setting (SP3-701) before you replace the development
unit, the PM counter of the development unit is reset, but the PM counter of the PCU is not reset.
• Therefore, before you replace the development unit, the manual new unit setting SP3-701 must be
done. Doing these in the wrong order will reset the counter of the PCU also.
