Does anyone have problems with these ? I am having a lot of pick errors and it seems to be related to the new universal covers..........????

Are these covers repacements for the tape guides? If so in retipping many thousands of cp6 nozzles we see that the window in the tape guide is often miscentered and the needle tip rubs on the same place every time it picks. I expect the miscentered guide could wipe the chip off when the nozzle is pulling out of the tape pocket.

The new universal guide replaces .7 - 1.8 mm tape covers. Fuji no longer makes the slitted type tape covers.

How can the tape guide be mis-centered ?

I just checked a hand full of scrap nozzles and the scuffing is usually on the right or left of the needle. If you have the cross pin facing you and looking down on the nozzle most of the scuffing or wear was on the left side, sometimes on both sides of the same needle. I have seen this condition for years on nozzles sent in for repairs and always assumed it was the tape guide causing it. The cp6 always goes to pick in the same orientation unlike the cp4. When you see this on a cp4 nozzle it will be scuffed all the way around the nozzle tip. One of my former employees here was asked to build a jig to straighten tape guides, could a damaged guide cause this?
