Safety Advice! Please note that the toner powder may have negative health impacts in case of incorrect handling. We recommend the use of protective masks or vacuum devices when filling your toner cartridge. Furthermore toner powder is highly flammable when it gets in contact with oxygen (in the air), because of wrong use. Please never use normal vacuum cleaners because it may cause an explosion. Instead we recommend our professional Toner Vacuum Cleaner Omega VAC.
