Kala - are those lines vertical (around the drum) or horizontal?
The calibration test pictures are blurry but I see some ghosting in there.... this means data problem.
Reseat the TSP cable and check for bent pins. Do you have a spare DDB-1-N card?
Make a backup, uninstall the Lotem application, delete the Lotem registry and reinstall the application clean or just reinstall OS and application.
If diodes are mixed up you will get vertical lines all across the plate but very close to each other - about 1mm apart - will not cause horizontal lines - these are coming from TSP, DDB most probably but may also be caused by the sync signal which I think it's generated in the Ebox (probably Strobe card or NUC but I'm not sure exactly which one)
Your application may not be not starting because of wrong or corrupted values in the registry.
