• The printer is installed on a solid, level surface.
• The room temperature is maintained between 10°C and 32.5°C. The relative humidity
is maintained between 20% and 80%.
• The printer is not located in a dusty place.
• The printer is not exposed to ammonia fumes or other harmful gases.
• The printer is not located in a hot or humid area (such as near water or a humidifier).
• The printer is not exposed to direct sunlight.
• The room is well-ventilated.
• The printer is not placed where the ventilation hole of the printer is blocked.
(2) Print paper
Check if :
• A recommended type of print paper is being used. [If the paper is too thick or too thin,
or tends to curl, paper jams or paper feed problems may occur, or printed images may
be blurred.]
• The print paper is damp. [If so, use fresh paper, and check whether the print quality
improves or not.]

occur.]

(3) Consumable parts
Check if:
• The "TONER LOW" message appears on the LCD display on the printer control panel
when a toner cartridge is installed in the printer. [If the message appears, replace the
