5. PREVENTIVE MAINTENANCE (PM)
5.1 General Description
The purpose of preventive maintenance (PM) is to maintain the quality level of this equipment by peri-
odically inspecting and cleaning this equipment and also replacing the parts whose replacement timing
has come according to the maintenance contract. There are PM kits packaged for each unit or a group
of parts with the same replacement number of output pages, allowing you to carry out efficient parts
replacement.
Also to maintain the quality level of the equipment, overhauling is required when a specified number of
pages has been printed or when a specified period of time has passed, regardless of the number of out-
put pages.
