5. Troubleshooting
* 1.90 is the default environment coefficient set for Environment Coefficient 9.
IMPORTANT
If you are not sure whether the uneven density problem you are trying to resolve is "Banding in
2-3mm pitch" or not, do the following procedure.
A) Set SP2-225-032 through 041 to "1.50", and print the job showing the problem.
B) Set SP2-225-032 through 041 to "1.63", and print the job showing the problem.
C) Set SP2-225-032 through 041 to "1.76", and print the job showing the problem.
If the problem does not occur in condition A, but occurs either in conditions B or C, the problem is
judged to be Banding in 2-3mm pitch.
• DO NOT print more than 10 pages with the above modified SP setting. Make sure to set each
SP back to default after the test.
