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.
