3. Turn the left parallelism adjust bushing to the rear (narrower) step by step toward the left parallelism
adjust bushing set position, where the thickness gauge starts shifting together with the CR unit. Then
shift the lever one step back to the front (wider) from the adjusted position.
4. Hold the upper side of the timing belt and slide it to move the CR unit from right to left or vise versa to
confirm that the thickness gauge set on the platen does not move.
5. Return the PG lever toward "+" (wide) direction to remove the thickness gauge, and slide the CR unit
right. Then place the thickness gauge by sliding it from the rear (PF roller side) into the front. During
this operation, don't contact the PF roller surface with the thickness gauge.
6. Set the PG lever to the "0" (narrower) position and shift the CR unit from left to right or vice versa by
holding the upper side of the timing belt.
7. Turn the right parallelism adjust bushing to the rear step by step to the right parallelism adjust
bushing set position where the thickness gauge starts moving together with the CR unit. Then shift
the lever one step back to the front (wider) from the adjusted position.
8. Hold the upper side of the timing belt and slide it to move the CR to confirm that the thickness gauge
set on the platen does not move.
9. Repeat the steps from 1 to 4 at the left end to confirm that the gap is correctly adjusted.
10. If the correct adjustment is confirmed, fix the left and right parallelism adjust bushings with the
screws (CBS, 3X6).
; When fastening the screws, be careful not to dislocate bushings from the adjusted position
; The tightening torque for the screws (CBS, 3X6) is 4.5 kg ~ 5.5 kg-cm.
