Have you checked the placement height? it will need to be set down to about 0.5mm - 0.6mm, whereas you can get away with 0.9mm for 0603. Not a Panasonic expert but I've seen this nearly every time a customer has taken the step down.

Hopefully it is just the part data a little bit off. But if that doesn't help, make sure the thickness sensor is calibrated bang on. And do the nozzle height adjustment. What are your nozzles and filters like, as far as being clean goes? I've put down 0402's at two different companies with MV2F's and the machines can do them well. Pickup miss usually means your data is on the small side or you need to clean nozzles and/or filters. We don't have panasonic equipment where I am now and it's going to bug me untill I can remember the pananame for the thickness sensor but I'm sure you know what I mean.

The Pananame for the thickness sensor is the line sensor.
