New p-head, mask, tractors.
Alpha is set correctly.
When doing an internal test,it will slide easily and head adjust.
At the first line, it stops,and bunches up ribbon on the right.
Print is perfect, no pins are pulling the ribbon.
The ribbon mech is actuating, but it seems the p-head is stopping the ribbon advance. Or could the drive motor be going bad?
I swapped the left I/O board that controls the ribbon/tractor selector assy. No change.
