    COUNTERMEASURES TO IMPROVE UNEVEN SHADES
               IN THE PRINTED IMAGE.
1.Model Name:
MX-5500N/6200N/7000N, MX-6201N/7001N
2.Symptom:
When printing halftones or solids, the image may have random areas of minor uneven shades
perpendicular to the output direction of the paper.
3.Description:
If the brush portion of the CL brush roller is long, it can apply a heavy load on the rotating
drum, thereby creating uneven shades in the printed image.
Reducing the diameter of the brush reduces the load applied to the drum, thereby relieving the
cause of uneven shades. Accordingly, the outer diameter of the CL brush roller has been
changed from 16 mm diameter to 15.5 mm diameter.
