Moire Due to Interference with Copy Original
Cause
Copying originals with certain line patterns may cause moire (wavy lines) on the copy. Combi-
nations of certain angles of screen ruling near 150dpi and certain Reduce/Enlarge ratios may
also cause moire.
Action
1. Reduce sharpness.
Secondary defect: Text is blurred.
2. Make copies at a different Reduce/Enlarge ratio.
3. Change the orientation of the original.
Fluctuation in Background Suppression Values for Copies of Originals
of Medium Density
When [Auto] is selected for originals with a background of medium density (0.5G), the effec-
tiveness of Automatic Exposure fluctuates for each job.
Cause
Since medium density (0.5G) is near the upper limit value for background detection, the Back-
ground Suppression value fluctuates according to the result of background detection, which
responds to variations in the original density and how the original is positioned.
Action
Select [Off] for [Auto].
Defects Related to Scan Print
Moire may occur when scanned images are printed.
Cause
This could be due to the resolution conversion process between the original and the printer
driver.
Action
Reduce sharpness.
Secondary defect: Text is blurred.
