5. Check to see if the fusibility is within the acceptable range.
• The required level of fusibility is as follows.
• The printed image does not come off.
• The toner does not come off even if it is lightly rubbed by a nail.
• The toner does not come off even if the image is wiped with an optical cloth.
Yes Go to the next step.
No Increase the fusing heat roller temperature further by 5°C.
If the problem persists even after increasing the value to "200", there is no other
solution.
6. In [Detailed settings] for custom paper, select 02: [For Belt Scratches] in [Interval] in 1243:
[Fusing Belt Smoothing], and then increase by one step the interval for polishing the
fusing belt by the fusing belt smoothing roller.
For example, if the present value is "Frequently", change it to "More Frequently".
This procedure is complete.
• The throughput is reduced if you decrease the print speed. As a reference, the throughput for
printing on A4 LEF paper is as follows.
High Middle Low
Pro C7500/ Pro C7500H 85ppm 69ppm 40ppm
When using Productivity Upgrade
Unit Type S14
85ppm 79ppm 40ppm
• After performing the solution, it is recommended to perform the color calibration of the external
printer controller.
• Select "Clear/Special" when using Neon Yellow, Neon Pink, or Invisible Red. Select "Metallic"
when using Gold or Silver.
Horizontal (Cross-track) White Streaks across the Paper
Thin horizontal white streaks 1-8 mm (0.04-0.3 inches) long appear across the paper.
