4. Appendix: Service Program Mode Tables
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.
SP2440 – Up to SP2304 001: Threshold 1
SP2441 – More than SP2304 001 Threshold 1, up to SP23204 002 Threshold 2.
SP2442 – More than SP2304 002 Threshold 2, up to SP2304 003 Threshold 3
SP2443 – More than SP2304 003 Threshold 3, up to SP2304 004 Threshold 4
SP2444 – More than SP2304 004 Threshold 4, up to SP2305 005 Threshold 3
SP2445 – More than SP2304 005 Threshold 5
These settings apply 1) only where the image is created in full-color on plain paper at full speed.

Sp1 K Bias
1
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 to 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 when printing on Special Paper
1 in the black-and-white mode and are applied only to the image area.
