If the main board was replaced , they should have taken the time to print out the service data list for a copy of all the settings to re-enter after. However, if the copier would not come up......they probably did not have that option. Making adjustments in service mode will probably fix the variation in copy quality. I'm pretty certain there are separate adjustments for the CIS when using ADF feed and when using the glass.
