2.Copier-specific Adjustments
• The subcode varies according to the area where the density is adjusted. Refer to the table below
and set the subcode for the area to be adjusted.
Subcode Area where the density is adjusted
0 Low density area
1 Middle density area
2 High density area
After setting the values, copy and check the copy image quality.
Only if the vividness of R (Red) is still insufficient even after all the above procedures have been
performed, must the service technician perform the next procedure.
(6) Select [05 ADJUSTMENT MODE]. Change the value for code [2905] to adjust the transfer (1st
transfer) roller bias output.
(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).
Paper type
Plain paper
Thick paper
Recycled paper
Thin paper
Thick paper 1/2/3/4
Special paper 1/2/3
Envelope
Transparency (OHP
film)
• 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.
<Notes>
• The adjustment may possibly decrease the density of G (Green), B (Blue) and K (Black)
extremely. Therefore, carefully perform the adjustment, while checking the copy image.
• Unless this adjustment changes the density of R (Red), return the values to the default (setting
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.
