This document describes how the tension bar settings are defined and what changes are allowed.
Tension bar settings in Media list
The media settings are accessible when double clicking a media from the media list in Calibrator.
Every media belongs to a category which has a default tension setting assigned: none, light or heavy. Depending on the category, the print manufacturer might allow this default setting to be changed. e.g. light papers can be printed with no tension bar or with a light tension bar. However, certain heavy materials will not allow the tension bar to be set to None, as this will cause head crashes.
How to change this media setting is explained in: Océ Colorado 1640: managing media and print mode settings
