The play of the tape is quite significant as I mentioned in an earlier thread. Tape width can vary between 8.1 +/- 0.2mm. Demos on 0201's are most likely done with 8.1 +/- 0.05mm tape. I guess you are referring to the cover tape pull, which can dispo

Again, I would like to refer to the tape dimensions and their deviations. In an 8 mm tape the distance from the sprocket holes to the tape pocket is 3.5 mm +/- 0.05 mm. This tolerance is easy to achieve, because in the manufacturing process of the ta

Hi Well as the feed movement is effected by means of a spring return force there really isn't that much to do apart from checking the spring tension and keeping the friction surfaces of the ratchet mechanisms of the feed sprocket and the top foil pu
