Loading the dual-roll spindles

With the spindles inserted into the Spindles Supports, Ensure that the differential hubs on the input

and output spindles are aligned with each other.

When both differential hubs are correctly positioned, use an Allen key 4 to tighten the screws and

secure them in place. If a differential hub is loose, the substrate could become skewed during

printing.

TIP:

You should tighten the screw until the washer touches the bolt. If you can still see the yellow

spring, tighten the screw further.

TIP:

It will be easier to load the roll onto the spindle if you lock the differential.

At each end of the spindle, unscrew and remove the outer parts of the hub, using an Allen key 4.
