Belt Platen
The belt platen should be adjusted out far enough so it is flush with, or slightly higher than the upper roller. The rollers are slightly crowned, that is they are higher in the center than at the edges. This crowning helps the belt to stay centralized on the rollers. The adjustment of the platen to the roller should be done at the high point, or center, of the roller.
1.Loosen the cap screw on the side of the belt housing with a 6mm Allen® wrench. This frees the in and out movement of the belt platen
2.Use a straightedge positioned in the center of the platen which extends over the upper roller. Adjust the belt platen in and out until the straightedge is just barely lifted off of the idler roller.
3.Tighten cap screw.
See the section on Belt Installation/Tracking for more information on adjusting the rollers for prop- er tracking.
