2856 Sp3 FC Bias
These SPs set the standard values of the electrical charges that are applied to 1)
create bias for image transfer from drum of each color (Y, M, C, K) to the ITB, 2)
create bias for image transfer from ITB to paper (PTR), and 3) neutralize the
charges on the both sides of the paper to separate the paper from the ITB (SepDC,
SepAC). These settings are used only for Y, M, C, K when printing on Special
Paper 3 in the full-color mode and are applied only to the image area.

These SPs (SP2861~SP2865) set the paper size correction coefficients for Special
Paper 3 relative to the settings done with SP2308 (Set Psize Thresh). All of hese
settings:
Apply to printing on Special Paper 3 in the black-and-white mode
Apply only to the image area
The title of each SP tells you the side and size where the setting is applied at ITB-
to-paper transfer, for example: "Side1:Size1:PTR" means the setting applies to
only Side 1 of Size 1 when the image is transferred from belt to paper at the PTR.
