Remember it's J paper to Cal the IIT, (Unless you change the NVM)

Also Check the Cabling from the IIT to the IOT

In that case you need to reset the nvm's and make default settings !

Go to dc919 and note the values. Then set all values to 0 in dc919.
Perform dc945, dc924 only for copy mode, and then dc950, dc 937.

Before maxsetup be sure sharpness/saturation is normal, autoexposure is on, image quality is normal color shift, light - darker = normal, color balance = 0.
Use test pattern 13120 and colotech paper.

After adjustments are done see the result and compare the new values from dc919 with the old values.
