IDS11 Moire Due to Interference With Copy Documents

Cause
When copying, interference with the document may cause moire. Combinations of certain
angles of screen ruling near 150 dpi and Reduce/Enlarge ratio may cause moire. Moire is more
likely to occur during reduction rather than enlargement.
Action

a. Use KO to change the Sharpness of Copy Settings from '2' (default) to '1' or '0'.
NOTE: Secondary defect: Text is blurred.
2. Make copies at a different Reduce/Enlarge ratio.
3. Change the orientation of the document.
4. The moire occurence frequency for each of the Document Mode are ranked as follows.

NOTE: However, changing the screen of Photo Mode to dither will increase its
moire occurence frequency.
To change the screen of Photo Mode:
