The correct answer is: C. Ozone filter
The ozone filter is a component in a laser printer that helps to remove ozone from the air. Ozone is a gas that is created as a byproduct of the laser printing process. It can be harmful to humans and animals if it is inhaled in high concentrations. The ozone filter should be vacuumed or replaced regularly to ensure that it is working properly and to prevent the build-up of ozone in the air.
The scanning mirror is a component in a laser printer that helps to direct the laser beam onto the drum. The toner cartridge is a component in a laser printer that contains the toner powder that is used to create the image on the paper. Neither of these components need to be vacuumed or replaced during preventative maintenance.
Here is a brief explanation of each option:
- A. Scanning mirror The scanning mirror is a component in a laser printer that helps to direct the laser beam onto the drum. The laser beam is used to create the image on the paper. The scanning mirror is not a consumable item and does not need to be replaced during preventative maintenance.
- B. Toner cartridge The toner cartridge is a component in a laser printer that contains the toner powder that is used to create the image on the paper. The toner cartridge is a consumable item and needs to be replaced periodically. However, it does not need to be vacuumed or replaced during preventative maintenance.
- C. Ozone filter The ozone filter is a component in a laser printer that helps to remove ozone from the air. Ozone is a gas that is created as a byproduct of the laser printing process. It can be harmful to humans and animals if it is inhaled in high concentrations. The ozone filter should be vacuumed or replaced regularly to ensure that it is working properly and to prevent the build-up of ozone in the air.
- D. All of the above This option is incorrect because only the ozone filter needs to be vacuumed or replaced during preventative maintenance.
- E. None of the above This option is incorrect because the scanning mirror and toner cartridge do not need to be vacuumed or replaced during preventative maintenance.
