! Before you install the new
PCU, make sure that you
adjust this plate to the
correct position.
! In a K PCU, this is always
fixed at the K position.
! In a CMY PCU, it is always
fixed at the Y position. You
must move the plate to the
correct position, or you will
not be able to install the
PCU.
" A bracket in the machine
blocks a pin on the PCU if
the plate is not set
correctly.
" This is to prevent PCUs
from being installed in the
wrong positions.
