Halftones are not accurately reproduced.

Explanation

Halftones are reproduced better.

When a photo image or gradational image is copied in Black mode with the Text/Photo mode option selected, halftones are not accurately reproduced. Select Image smoothing mode from among the original mode options, in order to reproduce halftones better in Black mode.

*Remember that the copy image obtained in Image smoothing mode cannot be stored in the e-Filing box.
