Have you gone into system settings, storing/calling of system settings and restored defaults? Also, have you locked in your SIT chart settings?

Which sims do you use when calibrating?

Make sure the optics are clean and keep calibrating until it looks good.

Did someone go into 46-2 and change the settings? Or in system settings and change default copy exposure?

clean the optics with alcohol and a soft white cloth. do not use any chemicals or colored rags. this should fix it.
