5. PREVENTIVE MAINTENANCE (PM)
5.1

General Description

The purpose of preventive maintenance (PM) is to maintain the quality level of this equipment by
periodically 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
output pages.
5.2 PM Display
5.2.1 General description
The maintenance times of the PM parts vary depending on the state of the parts, for example, if one
part is replaced due to a problem during the operation, the maintenance time of another part will
change accordingly. In this equipment, the optimal maintenance time corresponding to each part is
displayed on the control panel LCD.
The [process unit (K)] explained below is a photoconductive drum or a cleaner unit which includes a
photoconductive drum. The [developer material (K)] explained below is a developer material or a

treated as a threshold of the PM display", "the counter indicating the current number of prints and
driving time" and "the setting value which determines the display conditions".
The PM timing is displayed when the counter exceeds the setting value according to the display
condition based on "the setting value which determines the display conditions".

When "0" is entered as the setting value, PM timing is not displayed.
