Cleaning and Maintenance Service Maintenance Procedure Perform the following procedures whenever you check, service, or repair a printer. Cleaning the printer, as outlined in the following steps, assures proper operation of the printer and reduces the probability of having to service the printer in the future. The frequency of use, Average Monthly Print Volume (AMPV), type of media printed on, and operating environment are factors in determining how critical cleaning the machine is and how often it is necessary. Record the number of sheets printed. Recommended Tools Cleaning ■ Toner vacuum cleaner ■ Clean water ■ Clean, dry, lint-free cloth ■ Black light-protective bag Perform the following general cleaning steps as indicated by the printer's operating environment.
