[Cur.Paper Size] Transfer Current - Paper Size Correction
Paper Type -> N: Normal, TH: Thick, OHP, MT: Middle Thick Paper
2309
Corrects the transfer current for paper size.
When small paper is used for printing, the transfer current flows to the drum at the
non-image areas where the transfer belt touches the OPC drum. This may cause an
abnormal image due to insufficient current at the image areas.
NOTE: Increase only when an abnormal image (insufficient image transfer) occurs
on a small paper size. However, increasing the current too much may cause
image offset.

Adjusts the transfer belt position for color printing.
SP2-402-1 is valid only when auto correct (SP2-402-2) is disabled.
Auto Correct *BCU [0 to 1 / 1 / 1/step] DFU Alphanumeric
0: OFF, 1: ON
2402 002
Enable or disable the auto-adjustment of the transfer belt position.
• When SP2-402-2 is enabled, the transfer belt position for color printing is decided
in accordance with the result of the initialization processing.
• SP2-402-2 validates the setting of SP2-402-1, but does not affect the setting of
SP2-402-3.
Bk Mode Posit *BCU [0 to 500 / 130 / 10/step] DFU 2402 003
Adjusts the transfer belt position for monochrome printing.
SP2-402-3 is always valid regardless of the setting in SP2-402-2.
