LEdge Cor:Norm K Leading Edge Correction for Plain Paper: K
This SP sets the coefficient used to 1) correct bias at the leading edge for black
image transfer (ITB) 2) bias at image to paper transfer, and 3) correct the dc and ac
voltages applied at paper separation.
Notes: These settings apply:
• To the distance from the leading edge set with SP2422
• Only to black printing on plain paper at full speed (even when full-color is
selected).
001 ITB [0~400/1%]
007 Side1:PTR Note: ITB applies to both sides.
008 Side1:SepDC
009 Side1:SepAC
012 Side2:PTR
013 Side2:SepDC
014 Side2:SepAC
2422
LEdge SWT:Norm K Leading Edge Switch Timing for Plain Paper: K
Sets the switch OFF timing SP2421. The value selected is the number of mm from
the leading edge of the paper. These settings 1) apply only to black printing on plain
paper at full speed (even when full-color is selected), and 2) apply to to both sides of
a duplex page.
001 ITB [0~30/1 mm]
002 PTR [0~30/1 mm]
003 SepDC [0~30/1 mm]
004 SepAC
2423
TEdgeCor:Norm K Trailing Edge Correction for Plain Paper: K
This SP sets the coefficient used to correct bias at image to paper transfer for each
side of the paper. These settings are applied to the trailing edge for black printing on
plain paper at full speed and apply to black, even when printing in full color mode.
007 Side1:PTR [0~400/1%]
012 Side2:PTR
2424
TEdgeSWT:Norm K PTR Trailing Edge Switch Timing for Plain Paper: K
This setting sets the start timing for application of SP2423 at the trailing edge of
each sheet (Side 1, Side 2). This setting is applied to the trailing edge for black
printing on plain paper at full speed and apply to black, even when printing in f ull
color mode.
[-100~0/1 mm]
The “mm” distance is measured away from the trailing edge of the image.
