USER’S GUIDE

ADJUSTING THE PRINT DENSITY

The print density dial is located inside the printer. You can use it to adjust the amount of toner applied to the paper.

When the toner cartridge and drum unit are replaced, or if the operating temperature and humidity are high or low, print conditions may change causing darker or lighter printouts.

Use a screwdriver to turn the print density dial gently clockwise for darker printouts and counterclockwise for lighter printouts. The dial has been factory set to the middle position.
