PCDU Toner Collection Bottle
If you replace the bottle after the machine detects
that it is full or near-full, the machine
automatically resets the PM counter for the bottle
after replacement.
But, if you replace a bottle that is not full or near-
full, then you must reset the PM counter for this
unit. To do this, set SP 3902 019 to 1 before you
start to work on the machine.
