• If there is no room to reduce the print speed (interval between printing each sheet), there is no
other solution.
7. Print and check if the issue is within the acceptable range. (Print 50 or more A3 sheets.)
Yes Finished!
No Start over from Step 6.
• 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.
Uneven Density between the Left and Right Sides (at 40 mm (1.6 inches)
Intervals)
Uneven density between the left and right sides occurs every 40 mm (1.6 inches).
Cause:
This is caused by the bias of the charged electric potential between the front and back.
This is prone to occur when printing on a wintery morning after leaving the machine idle.
Solution:
Print a halftone image with a density of approximately 50% and check if there is a difference in density
between the left and right sides.
If the uneven density occurs every 40 mm (1.6 inches), use the following solutions.
1. In the [Machine: Maintenance] group on the [Operator Adjust.] menu, execute 0501-01:
[Execute Process Adjustment].
• Normally, the process control is automatically executed first thing in the morning, but in a low
temperature and low humidity environment, the adjustment of the charged AC bias may not
be sufficient by a single process control. In such a case, execute process adjustment manually.
