(Adjust the offset voltage of transfer roller bias for C (Cyan) and K (Black) so as to increase the density of R
(Red).)
• The code to use varies depending on the paper type and color to adjust. Adjust the value for the subcode
corresponding to the color for which you would like to improve the image quality. Set the value within a
range of "2" to "5" to obtain the highest density of R (Red).

value: 5).
• This adjustment may affect not only the copy image but also every image quality such as the
printout. Therefore, perform the adjustment, being aware that the image quality of all future
printouts will be changed, when printing out originals other than the one that is used for the
adjustment.
Caution after the adjustment
The adjustment may possibly cause offset failure, particularly when the highly colored original is copied in the
Photo mode. Therefore, carefully perform the adjustment, while checking the copy image.
Remarks
Enter a value within the recommended value range mentioned in the procedures. Otherwise, it may cause a loss in
MFP performance, including degradation in the image quality and a reduction in the life of the consumables.
