C A U T I O N

n

Ensure that the colors of the TONER CARTRIDGE to
be installed and the toner cartridge installation
position are the same.

n

Never use the TONER CARTRIDGE once taken out.

n

If you have moved the TONER CARTRIDGE from a
warm place into a cold place, leave it in a room
temperature for 1 hour or more. Otherwise, the printer
may produce abnormal printing due to condensation.

n

If toner gets on your hands or cloth, wash it off with
water. Toner is harmless to human body but hard to
come off once left on skin or clothes.

n

You must put used TONER CARTRIDGEs in a plastic
bag and disposed of them as inflammable, strictly
following the local regulation.
