5-3. Platen Drive Unit
The platen motor drives the platen and opens the chuck.
The platen drive uses two TN10 type belts (belt pitch: 1 mm) to minimize print nonuniformity. If a belt
skip is caused by jamming or other reasons, the belt may be damaged. In such a case, replace the belt
with a new one.
