Cleaning Your Machine

To maintain the print quality, follow the cleaning procedures below each time the toner cartridge is replaced or if print quality problems occur.

NOTES:

•While cleaning the inside of the machine, be careful not to touch the transfer roller, located underneath the toner cartridge. Oil from your fingers can cause print quality problems.

•Cleaning the cabinet of your machine with products containing large amounts of alcohol, solvent or other strong substances can discolor or crack the cabinet.

Cleaning the Outside

the cloth slightly with water, but be careful not to let any water drip onto or inside the machine.

Cleaning the Inside

1Turn the machine off and unplug the power cord. Wait for the machine to cool down.

2Open the front cover and pull the toner cartridge out, lightly pushing it down.
