used toner and empty bottles and cartridges), and AIO unit out of the reach of children.
ï‚· Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is not exposed to direct
sunlight.
ï‚· Do not use a vacuum cleaner to remove spilled toner (including used toner). Vacuumed toner may cause a fire or
explosion due to sparks or electrical contact inside the cleaner. However, it is possible to use a cleaner designed
to be dust explosion-proof. If toner is spilled over the floor, sweep up spilled toner slowly and clean up any
remaining toner with a wet cloth.
Handling the development unit cooling system
For the machines installed the development cooling system:
1. The development unit cooling system circulates propylene glycol from a sealed tank through hoses that pass
behind cooling plates on the sides of each development unit.
2. The coolant tank is located at the bottom of the cooling box on the back of the main machine.
3. Always obey local laws and regulations if you need to dispose of a tank or the propylene glycol coolant.
4. The tank must never be emptied directly into a local drainage system, river, pond, or lake.
5. Contact a professional industrial waste disposal organization and ask them to dispose of the tank.
