* The double counter value of the life is raised after the occurrence of the error 50 (The
drum unit reached its life). Then the discharge is produced by the dirt of the corona wire,
and the error 83 appears by detecting the dirt of the electrification current of the HVPS
PCB.
When the error 83 is appeared, the performance of the drum unit cannot be maintained.
Stop use of the drum so that the printing quality deteriorates.
