Horizontal (Cross-track) Black Streaks at the Edge of the Image

The horizontal column density fluctuates at 11 mm (0.4 inches) intervals on the right edge perpendicular
to the paper feed direction. This fluctuation does not occur in the area that is 90 mm (3.6 inches) or less
from the trailing edge.
Cause:
The line speed of the transfer timing roller is slower than that of the paper transfer roller, causing the
pieces of paper to pull each other and come in and out of contact with the front of the paper transfer
nip, resulting in uneven density.
Occurrence conditions:
• Printing is performed at low temperature or humidity
• Halftone images are printed
Solution:
1. If the paper is not registered as custom paper, register the brand of the paper.
2. In [Detailed settings] for custom paper, select 1341: [Motor Speed].
3. Check if the line speed of the transfer timing roller is set to 0.5% or higher.
Yes No further improvement is likely.
