2. PREVENTIVE MAINTENANCE (PM)
2. 1 Types of Preventive Maintenance
The following two types of preventive maintenance should be performed:
(1) General maintenance
General maintenance should be performed based on the value of the PM counter (08-857).
This maintenance, which covers the black developer unit as well as the entire machine, should be
conducted in conjunction with the replacement cycle (For FC-22: every 30K Copies, For FC-15:
every 20K Copies) of the black developer material.
(2) Color maintenance
Color maintenance should be performed based on the value of the color PM counter (08-897).
This maintenance, which is performed with a focus on the color developer units, should be con-
ducted in conjunction with the replacement cycle of the color developer materials.
FC-22: every 30K copies
FC-15: every 20K copies
The replacement cycle (counter value) of color maintenance is determined by the ratio of color copy
to black copy, as shown by the following table, "Variation in PM cycles due to color/black output
ratios".
Variation in PM cycles due to color/black output ratios
* Therefore, replacing parts, cleaning and coating oil for the paper feeding unit, scanner unit, trans-
fer/transport unit, fuser unit, all should be checked and maintained in conjunction with the replace-
ment cycle of the black developer material.
e.g. )Replacing fuser rollers : At the 3rd cycle of replacing black developer material
(30K × 3 = 90K copies)
Replacing the transfer belt : At the 4th cycle of replacing black developer material
(30K × 4 = 120K copies)
* For the details of maintenance items, refer to the checklist described later.
* Yields are based on factory defaults.
