problem. 1128MFP, when scanning in color to pc. the customer gets sometimes lines using DP.
-slit glass is clean.
- settings with the test chart are done , SIM 425, 411.
- changed settings in U068, tested all values also from -33 to +33.
- changed ISU, ok for a while then problem reoccurred.
Someone a good hint?
