. The 170PAX4 drive system uses a series of pitch timing belts and pulleys. The 

staged belt drive systems consist of one stage from stepper motor to a compound pulley and 
another serpentine stage from the compound pulley to the pinch and peel rollers. The final 
stage is from the compound pulley to the platen shaft.

The serpentine belt uses a stationary backside idler pulley to maximize timing belt wrap angle 
around the pinch and peel roller pulleys. The serpentine belt also uses a spring-loaded 
backside idler pulley to maintain belt tension during backfeed. Both serpentine and platen 
shaft belts are constantly pretensioned by means of an extension spring.
