(7) Enter adjustment mode [05]. Change the values for codes [570 to 572] or [693 to 695] to set the background peak of range correction to "fixed" in manual copy density mode.

•The code to use varies, according to the density option (auto or manual), original mode, (Text/Photo, Photo or Text) and use of the RADF (MR-3018). Adjust the value for the [05] code corresponding to the condition for which you would like to improve the image quality and set "1" in ten place.

*Set value (Ex.: To set the background/text peak in manual and auto copy density mode to "fixed")

1 1

One place: Set the background/text peak in auto copy density mode to "fixed" — See the table below for further information.

Cautions after the completion of the adjustment

The adjustment may possibly cause an increase in the amount of toner used, moiré, blurred text (small, dark text blurred), diminished photo images or gradational images (less accurate reproduction of halftones). Therefore, carefully perform the adjustment, while checking the copy image.

Remarks

Enter the value within the recommended value range mentioned in the procedures. Otherwise, it may cause a loss in copier performance, including degradation in the image quality and reduction in the life of the consumables.
