fluff adhered to the laser exposure path or waviness of Developing
Unit sheet
[Symptom]

The arrow [b] indicates the direction of feeding.
[Cause]
If fluffy foreign matter is adhered to the laser exposure path which is located between the Laser Scanner Unit and the Developing
Unit or if the Developing Unit sheet is wavy, the laser light is blocked and a latent image cannot be formed. As a result, the
symptom occurs.
