2. PREVENTIVE MAINTENANCE TABLES
2.1 MAINTENANCE TABLES
 The amounts mentioned as the PM interval indicate the number of prints.
2.1.1 PREVENTIVE MAINTENANCE ITEMS
Chart: A4 (LT)/6%
Mode: 3 prints/job
Environment: Normal temperature and humidity
Yield may change depending on circumstances and print conditions.
Symbol keys: C: Clean, R: Replace, L: Lubricant, I: Inspect
 Yield Parts: The parts mentioned in these tables have a target yield. However, the total
copy/print volume made by the machine will not reach the target yield within the
machine's targeted lifetime if the machine is used under the target usage conditions (ACV,
color ratio, and P/J). So, these parts are categorized not as PM parts but as yield parts
(EM parts). The parts with "(R)" in this table are yield parts.
