2756 Sp1 K Bias
Set Bias for Special Paper 1: K. 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 1 in the full-color mode and are applied only to the
image area.
1 ITB:K
[0 to 70/0.1 μa]
2 ITB:M
[0 to70/0.1 μa]
3 ITB:C
[0 to 70/0.1 μa]
4 ITB:Y
[0 to 70/0.1 μa]
13 Side1:PTR
[-100 to 0/1 μa]
14 Side1:SepDC
[0 to 10/0.1 μa]
15 Side1:SepAC [8 to 12/0.1 kV]
21 Side2:PTR
[-100 to 0/1 μa]
22 Side2:SepDC
[0 to 10/0.1 μa]
23 Side1:SepAC [8 to 12/0.1 kV]
These SPs set the paper size correction coefficients for Special Paper 1 relative to the
settings done with SP2308 (Set Psize Thresh). All of hese settings:
Apply to printing on Special Paper 1 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 the first side of
Size 1 when the image is transferred from belt to paper.
