White Spots/Toner Blasting
White spots of about 0.2mm to 0.3mm appear throughout the entire image.
Toner scattering around solid images
Cause
Electric discharge at the PTR unit
This is likely to occur if:

Printing in the low humidity condition

Using paper which has high resistance

Printing on the 2nd side in the duplex printing (Paper resistance is increased after paper has been
passed through the fuser unit because paper looses its moisture in the fuser unit.)

Printing a image which has a large mass amount of toner
