Panasonics are good machines as long as you do the proper and timely PM's they recommend. Plus with my past history and from others that I here, their feeders are some of their biggest down fall. That's typically why they have to introduce new style

Nick, In siemens terms: Fuji has the ability to check "ink spot" which I assume is what you are doing now. The only difference is the vision capabilities between the two machines. You do not have the freedom of siemens type gray scale with Fuji. Yo

Without using a glass plate you could check if your jaws could properly align the compomnents by writing a small vice versa program. Place a component in a 0 degree angle and another one right next to it in a 180 degree angle. Built up a line of lets
