CP6-4000 nozzle centering errors?

CP6-4000 nozzle centering errors? | 29 May, 2008

Hi all, Is it normal for some of the small nozzles to be rejected by the wide view camera? Every time I do a nozzle centering the narrow view camera shows green circles for nozzles 1,2,3,4. The larger ones (5 and 6) show the asterisk. The wide view camera shows most green circles for the samall nozzles but about 7 of then show NG (position varies:1,2 or 3. Different heads of course) . I tried to change them with new ones but I keep getting the same error. I do not know if the new ones are perfect though. They may have been improperly stored. But, is this normal or should they all be green? More info: The rejections seem tobe that it does not find the nozzle because it seems to measure first and get a yellow asterisk, then it measures again and it get the results good or not. Well on the above I mentioned I get the red X on the first pass. Also If I swap the bad nozzle to a different location it fails in the new location.

Any help would be appreciated, thanks.

The nozzles get centered at zero degrees and 180 degrees. I believe the yellow asterisk is the measurement at zero degrees, when it rotates to 180 is when you will get a red X or a green O. (In other words the yellow asterisk is normal)

I think you answered your own question. If you say that you are moving the nozzles to different heads and they fail... then its the nozzle. Make sure your light levels are correct and your nozzle back disk need to be clean and the same color on ALL nozzle sizes.

Another sticky issue is that if you use after market nozzles especially mixed in with Fuji nozzles the Anti-Marking Illumination Disks can be different enough that the vision system will reject nozzles.

Thats what I meant when I said they all need to be the same color.

I've had some that under normal light they looked the same but when the UV light hit them they were very different.

The right paper incorrectly applied can be a problem also. I have seen it on even new Fuji nozzles with the illumination disk bunched up on one side of the tube with a gap on the opposite side.

Thank to all for the help. The problem was the reflective disk. They're all green now.

Thanks again.

I got another error but I'll start a new thread because it is not related to the disks.
