3. Printer-specific Adjustments
(5) Enter adjustment mode [05]. Change the value for code [2905] to adjust the transfer (1st transfer) roller bias
output.
(Adjust the offset voltage of the 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).

* Never change the values for subcodes other than the above. Otherwise, it may cause a loss in MFP
performance, including degradation in the image quality.
<Note> • The adjustment may possibly decrease the density of G (Green), B (Blue) and K (Black)
extremely. Therefore, carefully perform the adjustment, while checking the printout.
• Unless this adjustment changes the density of R (Red), return the values to the default (set
value: 5).
• This adjustment may affect not only the printouts but also every type of image quality such as
the copy image. 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
Nothing in particular.
Remarks
The saturation adjustment does not affect black or gray areas on the printout.
