There should be no gap.
Adjusting folding roller Bearing holder
1. Loosen the 2 screws holding the bearing holder of each roller. Slide the folding rollers 1 and 3 along the elongate hole taking the roller 2 as reference so that these rollers are pressed up the roller 2. 2. Adjust the folding roller 4 taking the folding roller 3 adjusted in the step 1 as reference. * Each roller should be symmetrical to the left and right, and there should be no gap between rollers. (Asymmetrical roller pressure causes snaking or wrinkling.)
* After adjustment, a roller should rotate without flat belt and all rollers should drive together. Screw shaft
