MUTOH Ultima - EPOS System → Check Sensor

User’s Guide – Ultima cutting plotter
81 AP-75032, Rev 2.2, 20/04/07
5.6.7. EPOS system → check sensor
When you want to print on a grey vinyl for example, it is possible that the Ultima will not detect the frame
(bounding box) on the vinyl. That’s the main reason of the “Check sensor” menu. When you put the vinyl in
the Ultima, and you do a sensor check, and the ACD value is black, it will be impossible to do a contour cut
on that vinyl. When the ACD value displays white, you will not have any problems.
You can also use this menu to check if the Photodiode still works. Just draw a black box on a white paper,
and check if the Photodiode displays the right colour.
