• 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:
25. 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.
26. The coolant tank is located at the bottom of the cooling box on the back of the main
machine.
27. Always obey local laws and regulations if you need to dispose of a tank or the propylene
glycol coolant.
28. The tank must never be emptied directly into a local drainage system, river, pond, or lake.
29. Contact a professional industrial waste disposal organization and ask them to dispose of
the tank.
