4. Hold the measurement paper so that it copy
reaches the Heat Roll & the Pressure Roll.
5. Take out the measurement paper after closing
the machine for approx. 8~10 seconds
6. (Fig. 2): Open the measurement paper gently.
Take measurements at the positions 75 mm
from the both sides of the paper respectively
(at two positions on the fold made when the
