Preventive Maintenance (Pm) - Toshiba e-STUDIO2330C Service Manual

19. PREVENTIVE MAINTENANCE (PM)

19.1 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.
19.2 PM Display
19.2.1 General Description
The maintenance timing for the PM parts of the process unit, such as the drum and developer material,
and the PM parts of the units other than the process unit, such as the 2nd transfer roller and fuser belt
varies depending on the conditions of the use, such as the ratio of color/black printing. Therefore, this
equipment shows the appropriate maintenance timing of each part on the control panel LCD.
19.2.2 PM Display Conditions
The conditions of the PM display consist of the codes of the setting mode (08) for "the setting value
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".
• Setting value treated as a threshold of the PM display
Note:
When "0" is entered as the setting value, PM timing is not displayed.
