Go to service mode>copier>option>Body>DFDST-L1 and DFDST-L2, decrease the value.

Go to service mode>copier>option>Body>DFDST-L1 and DFDST-L2, decrease the value.

Take the setting down to a 1 on both of these.

Also in COP>OPT>BODY set DF-BLINE to "1",then reboot the machine. This will turn off edge emphasis in image processing when using adf and reduce incidents of lines.
