Solution
If printed images are affected by banding in different colors, execute "Adj. Quality" for adjustment of the paper feed amount.
Use "Manual" adjustment with highly transparent media or other paper for which "Auto(GenuinePpr)" or "Auto(OtherPaper)" cannot be used.
"Manual" adjustment requires you to enter an adjustment value after a test pattern is printed.
NOTE
- Always check the "Adj. Priority" values before using "Manual" adjustment.
- If additional fine-tuning is necessary after "Manual" adjustment, use "Adj. Fine Feed".
- Use Adjust Length to ensure that lines in CAD drawings are printed at exactly the right length.
- Use paper of the same type and size for adjustment as you will use for printing.
