7.2.4 Pinch Roller Pressure Adjustment
How to adjust the pinch roller pressure
(1) Detach the center cover (see Subsection 6.1.3).
(2) Change the hold-down force switching lever to the Strong position.
(3) Place the pinch roller on the grit roller.
(4) Sandwich the stainless steel plate jig as shown in the figure below and catch the push pressure wire jig
on the pinch roller shaft.
(5) Pull the wire of the push pressure wire jig in the direction of the arrow with the 10 kgf push-pull gauge.
Note *Be sure to pull in the correct direction.
*Be sure to pull at the angle shown in the figure above (the angle at which the wire jig is almost
touching the Y rail).
(6) Read out the value at which the stainless steel plate jig slips out.
The pinch roller pressure should be 6.5 kg ±0.25 force.
The pressure difference between each pinch roller should be less than 0.4 kg.
