Pinch roller question

[bruce]

I have a sp540i and a sp 300.
The sp300 only has 2 pinch rollers and does not seem to track right. We have extra track rollers for our so540i. They just dont seem to push on the bar on the sp 300. Are they interchangable?
Or how can I add more pinch rollers on a sp300.
Thanks

Raise the bar before attempting to fit the push on type. Also, if you are not using the plastic spool carriers, there will be too much drag and the media will track wrong.

There is no possibility to add pinch rollers to the SP300/SP300V.

The pinch rollers should be interchangeable (the pinch rollers only, not the complete units with the holders), but: the outer pinch rollers are different than the middle pinch rollers (they are slightly conical).
