Symptom

White spots appear randomly on solid images.

Condition

Paper containing a lot of paper dust

Cause

The following are the 2 possible causes of this symptom.

1. Toner adheres to the paper dust instead of the paper. After the printing process, the dust comes off with the toner and leaves an unprinted white spot.
2. Paper dust falls on the paper path, causing succeeding sheets to catch the paper dust. Then, similarly to Cause 1, toner adheres to the dust instead of the paper.

Solution

1. Solution for paper containing a lot of paper dust Fan the paper to remove paper dust before setting the paper in the tray.
   Note: • If the paper contains a lot of paper dust to the extent that the dust is clearly visible when fanning the paper, avoid using such paper stock.
2. Solution if there is paper dust on the paper path Wipe the paper path leading from the registration unit to the fusing unit [A] with a damp cloth.
