If you install a new drum unit only, the machine does not
detect it automatically.
Then, you must reset the PM counter for the drum unit.
To do this, set SP 3902 009 (K), 010 (C), 011 (M), or 012 (Y)
to 1 before you start to work on the machine.
If you install a new development unit only, the machine
detects it automatically and resets the PM counter. But, the
ID chip in the new development unit will also reset the PM
counter for the drum if you do not do the following:
Set SP 3902 001 (K), 002 (C), 003 (M), or 004 (Y) to 1
before you start to work on the machine.
If you install a new PCDU, the machine detects it
automatically. Do not change SP 3902.
