First I want thank you for the answers.
The trouble began in January of this year, when i look the film and verify that are a light stripes from left to right on 80% screening. You can see on attachment 01.jpg .
These light stripes were not always present, so we continued the work. Afther defect is changed and make work impossible. You can see on attachment 02.jpg and 03.jpg.
Then we called a qualified engineer. This man have cleaned a lens near a film side, on the right looking by laser (laser SOL sensor i think), after he has checked the voltages on the card and corrected a tension that was 0.5 V lower.

The engineer also checked >menu, diagnostics, spinner test, start test etc.< and was amazed at the perfection of the values.
Finally adjusted the laser BIAS and corrected two trimmers on laser group. That's all.
Mako now works well, but sometimes has a not previously presented defect.
Yo can see on 04.jpg. It seems that the points are deformed from left to right.
Now i think that first defect is a laser and that last defect is a spinner.
But I still don't understand why the Mako controls (>menu, diagnostics, spinner test, start test etc.<) give the correct values??!!
The fault now is really unusual, but when it si present on 64x44 film is a waste of money.
The engineer says that the LASER/SPINNER group is at the end of life.. What do you think?
Thanks
