Did you also move the NVRAM to the new board? Try putting in all the non-default settings (from the birth certificate).

.... and if nothing helps - then $$$$ REPLACE TX belt unit $$$$$$$ costly but sometimes you have no other way to fix it

I would thoroughly clean the ITB unit, mainly the inner belt and upper roller before I replaced the whole unit. The belt needs to be transparent, and the roller must be reflective. Clean all 3 ID sensors and run the forced line positioning (rough then fine). If the transfer belt is in bad shape, you can just replace it as opposed to the whole unit usually. Also make sure the ITB cleaning unit brush and/or blade is not worn in the center were the ID patches are developed on the belt.

Poor ID patch density due to worn out drums/developer units can cause line positioning to fail also.

Thanks for all the info got it sorted out by re inputing all the non default settings
