NOTE
• If an unpacked imaging unit is placed in direct sunlight (or room light for long periods of time), the unit
may be damaged.
• For best performance, use only original toner.
• The machine should be used only in a clean, dust-free environment with adequate ventilation.
Printing with a non-genuine imaging unit may reduce not only the print quality but also the quality and life
of the machine itself. Warranty coverage does not apply to problems caused by the use of a non-genuine
imaging unit.
