Hi all film-plotters.
We started getting unusable films.
Whole stripes of the image moved aside. All the image gets exposed, but some parts (stripes) are moved.
Seems that during plot some imaging data gets off sync, as if the spinner starts plotting too early (or too late) several times along the way.
Restarting didn't help. Replacing boards (SOMC and ACRI) didn't help either.
