Symptom:
The image density decreases with continuous printing, especially in solid image areas (though it is within specification).
- This does not occur in text areas.
Cause:
This may occur due to the condition of the developer, and also occurs more easily when repeat prints are made from the same original.
Solution:
Change the following SP modes as shown.
- SP3-629-001 (Vc Vsp): Set to 530
- SP3-629-101 (Vb Vsp): Set to 330
- This will increase the amount of toner used to develop the image.
- As a side effect, this will shorten the yield of the toner bottle.
