2541 Thk:FC:LL Thick Paper: FC Low
2542 Thk:FC:ML Thick Paper: FC Medium Low
2543 Thk:FC:MM Thick Paper: FC Medium
These SPs set the paper size correction coefficient for the image to paper transfer
bias threshold values calculated based on the reading of the absolute humidity from
the temperature/humidity sensor and the thresholds set with SP2304.
SP2541 – Up to SP2304 001: Threshold 1
SP2542 – More than SP2304 001 Threshold 1, up to SP2304 002 Threshold 2.
SP2543 – More than SP2304 002 Threshold 2, up to SP2304 003 Threshold 3
These settings apply 1) only where the image is created in full-color on thick paper
(128~256 g/m
2
) at full speed.

2601 OHP K Bias Set Bias for Transparency: K
This SP sets the following standard bias voltages applied for the image area on OHP
in the black-and-white mode at 1) image transfer from drum to ITB, 2) image transfer
from ITB to paper, and 3) at paper separation from the ITB.
