Figure 12: Rollers in poor condition. Top: melted plastic stuck onto bottom roller (part AM4-7a). Bottom: Top Roller 

(AM4-6a) split from heat. The heat guards on this machine were removed, and heat was left on without machine 
running, leaving the roller to face the heater block on this side until the rubber degraded. The top roller can be 
repaired; the bottom one cannot.
