White Spot Blisters
White spots 0.3–0.5 mm (0.01–0.02 inches) in diameter surrounded by denser spots (blister-like white
spots) appear.
Cause:
This may occur when:
 a solid image is printed on coated paper
 solid image are printed on both sides
 printing is done at low temperature.

Check for insufficient toner fusing. (Insufficient Toner Fusing)

halftone or blank areas, accumulated toner is causing uneven spots.
