7) Inspecting the cramp pressure
Check to see if the lock release lever clicks (in the same manner those of other
feeders click) when you attach the tape feeder onto the feeder bank and close the
lock release lever.
If the lock release lever does not click, make the following adjustments.
P
Eccentric axis C
Setscrews A (two)
Setscrew B
1) Loosen the setscrews A (two) and setscrew B.
2) Rotate the eccentric axis C and adjust the load “P” imposed when you close the
lock release lever with the tension gauge so that the load can be 12 to 17 N.
3) Tighten the setscrew B, and tighten up the setscrews A with 1.9 to 2.3 N·m.
4) After tightening up the setscrews A and B, repeat operating the cramp several
times to check that the load “P” is 12 to 17 N.
Note: Assemble the eccentric axis C downwards.

8) Inspecting the pick-up position
To maintain the component pick-up accuracy, regularly check and adjust the
pick-up position.
If you happen to give a shock to or impose unbearable load on the tape feeder,
check the pick-up position also.
If the pick-up position is shifted from the regulated one, it may increase the number
of pick-up errors or increase the cycle time due to unavailability of a simultaneous
pick-up of two or more components.
CAUTION
To adjust the pick-up position, the dedicated feeder inspection jig is required.
For the inspection jig, refer to its Instruction Operations of the inspection jig.
