Time to replace the toner cartridge

Toner cartridges are consumable products. When there is not enough toner, this may cause the case where white streaks appear on the printed paper in longitudinal direction, or the printed paper comes out faint or uneven. If this type of symptom may occur, perform the following procedure before replacing the toner cartridge. You may be able to print for a while until the toner is used up completely.

If this does not solve the problem, replace the toner cartridge with a new one.
