Which action supports an effective printer preventive maintenance program?
- Reset the printer page counters if available.
- Replace laser printer toner at set predetermined time intervals.
- Clean inkjet print heads when they stop working.
- Disconnect the printer from the power source when it is not in use.
Explanation: Resetting the page counters will assist in documenting printer usage and planning future maintenance. Cleaning parts only when they are no longer working, replacing consumables at set time intervals regardless of need, and disconnecting the printer from the power when it is not in use are not related to a preventive maintenance program.
