K PCU Charge Wire Replacement
! The main points to remember are as follows.
" The corona wires are thin and break easily. If a
wire breaks, remove all the pieces from the
machine.
" Do not use alcohol to clean the charge corona
unit.
" Do not touch the surface of the new grid mesh.

# As in the V-C2, the K PCU uses a corona wire. The other PCUs use a charge
roller.
