VIII. MAINTENANCE AND SERVICING
A. Periodic Replacement Parts
• There are no parts which require periodic replacement in this printer.
Note: Periodic replacement parts are the parts that must be replaced at regular intervals, even
if they are functioning properly and show no signs of wear. (Failure of these parts can
seriously affect the performance.) These parts should be replaced during a regular ser-
vice visit closest to the end of the parts expected life.
B. Expected Service Life of Consumable Parts
Consumable parts are expected to require replacement at least once during the warranty peri-
od of the printer, due to deterioration or damage. The life span of consumable parts is expressed
in terms of hours or number of prints processed. Replace them when the parts are proven
faulty. Table 4-8-1 shows the expected life of consumable parts.
