3.4.5 NEW PCU
There are two types of PCU. Before replacing a PCU, make sure that you have the correct
type:
The K PCU contains a charge wire unit, used only for black.
The YMC PCUs use a charge roller. This PCU type can be used to replace Y, M, or C
PCU.
1. Remove the seal from the new PCU (the seal is similar to the permanently attached
one, shown above, but you can tear it off).
2. Stick the seal on the guide sheet provided. This reminds you which SP codes must be
set for the PCU later.
