2972 Forced Soft Count ON Threshold - t2 DFU`
This SP sets the threshold value to trigger forced software count. This count is done for
the OCFS software count for ink consumption and OCFS ink supply filling
[0 to 5/0.6/0.05 sec]
2973 OCFS Position Check DFU
If the temperature/humidity sensor inside the machine measures a significant change in
the humidity, this could affect the operation of the machine.
• A humidification correction value has been devised to alter the "full position" of the
OCFS feeler to compensate for adverse temperature and humidity.
• Normally, the sub tank feeler points straight forward when the tank is full.
However, the machine can automatically shift the full position automatically to
compensate for adverse temperature/humidity.
• The machine adjusts the position and the sensor "learns" the new full position.
These SP codes adjust this procedure.
