4. Image Quality Problem: Full Page
[A]
[B]
[A]: Ghosting occurs at an interval of 278 mm (10.9 mm) (one rotation of the fusing belt).
[B]: White stains on the entire image
Cause:
Because of the heat on the fusing unit, the surface profile of the fusing belt may be transferred to the
transparent film, causing white ghosting on the part of the transparent film where images are not printed.
Furthermore, if toner wax adheres, ghosting occurs on the corresponding area.
Solution:
(a) Decrease the printing speed
1. If the paper is not registered as custom paper, register the brand of the paper.
2. Decrease the line speed. This will decrease the throughput, but is it OK?
Yes
No
3. In [Detailed settings] for the custom paper you are using, select 1231: [Print Speed], and
then decrease the value in the following corresponding settings by one level.
• 1231-01: Print Speed: BW/FC/FCS: BW/FC/FCS
• 1231-02: Print Speed: FCS: Clear/Special
• 1231-03: Print Speed: FCS: White
• 1231-04: Print Speed: FCS: Metallic
• 1231-06: Print Speed: S: Clear/Special
• 1231-07: Print Speed: S: White
• 1231-08: Print Speed: S: Metallic
