Ricoh D124-17 Service Manual page 767

If the machine remains idle in a low humidity environment, the ink sub tanks can dry out and the OCFS
feelers may not return to their correct positions after air is purged from the tanks. This misalignment could
prevent achieving the correct negative pressure in the sub tank.
To prevent this problem:
• A correction value to counteract the effect of humidity 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 of the feeler automatically to compensate adverse
temperature/humidity.
