When performing a pickup test, it is necessary to index the parts because the test does not automatically index them and there are certain cases in which indexing must be performed a certain number of times, depending on the feeder. The feed count list is shown below.

Note: Items in the () indicate that it might be possible to use that amount to index the part for the pickup test. However, there are times when a Y-axis movement tolerance error occurs and the pickup test cannot be performed because the pickup position will change based on calibration compensation or any pickup offset values (part size or smaller) and therefore the pickup position will be outside the valid movement range.
Indexing the tape
1. Check the chart and push the index button the number of times required to index the part forward.
Returning the tape
1. Check the part and index the part back the number of times it was indexed forward by pushing the back button the same number of times.
Note: The take-up lever is designed to prevent looseness in the top film when rotated correctly (i.e., the tape is indexed forward). When rotated in the opposite direction, looseness in the top film develops. Eliminate this looseness manually by opening the take-up lever and gently pulling on the top film and then returning the take-up lever.
