The lookup camera is central to the four nozzles, so it will not have a perpendicular view at the nozzles.
I don't know the nozzle size I have, but if I know the next largest won't work for 0402.
1. Check the nozzle is clear for good suction. There was one time I had an 0402 stuffed length ways in a nozzle obstructing the air pressure.
2. Check the nozzle end is clean. I clean the tips before every build. Mostly in case any paste/flux residue causes stickyness.
3. Check the accuracy of the tape feeding. If not enough, the tape indexing might have a little bit of variation. I often use a feed strength of 40, as when too high, it causes the parts to bounce out of the pockets.
4. May sure to index twice, then set the pickup alignment for that feeder. Very important... set the alignment target for the pocket square, not the component. Index and double check it's lining up.
