VIII. MAINTENANCE AND SERVICING
A. Periodic Replacement Parts
• No parts 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 service visit closest to the end of the parts expected life.
B. Expected Service Life of Consumable Parts
Shown below are the average life expectancies (number of prints) of parts that may need to be replace due to deterioration or damage at least once prior to the elapse of the warranty period of the printer. These parts should be replace when faulty.
