Note
Media baskets can influence media tracking. Empty media baskets will avoid that media movement is disturbed. It is recommended

to disable (close) media baskets (front and back) in case of cutting lengths over 6 meter. In this case make sure the floor is clean
and assure enough space at the front and the rear of the plotter in order to let the media move freely in an out the cutting plotter.
