White Spots/Toner Blasting

White Spots
White spots of 0.2 to 0.3 mm (0.008 to 0.01 inches) in diameter appear.
Toner Blasting
Toner is scattered around a solid-fill print.
Cause:
This may occur if:
• Printing is done at low temperature or humidity
• Paper dust may stick to the paper and produce white spots.
• Some types of paper, such as recycled paper, roughly cut paper, and high-friction coated paper
produce a lot of paper dust, which will likely stick to the paper.
