Has anyone experienced scratching in the image when running heavier stocks. We run a 350gsm coated board on our Igen3 and we always suffer from scratching whenever we run it. It shows little or no consistency, at first we thought it may have been bits of dev sticking in the tab blade area but we also get it when printing simplex. Anyone got any ideas?
Thanks

Whenever I have had scratching problems it has almost alwatys been the Tab Blade. It doesn't take much for them to get something on them that will cause the scratching.. Have had the problems a dozen or less times over the last 2 years...

Dale's right.

I don't know for sure if you are having the same problem as we once had but here is what we did. For the media attributes, try lowering the voltage af the transfer corotrons in the Media Attributes tab.
Transfer A: 100
Transfer B: 110

Now these worked for use and we were using a 14mil poly blend, pretty much plastic. At first it would not bond with the toner/developer and would scratch the image. After lowering the voltage it worked. Try lowering in increments of 10 to see if it helps. Good luck.

Hard stop the press to figure out what area is causing the defect. If the defect is not present on the PR or in the prefuser area, watch the sheet as it enters the fuser. I have seen heavier stocks buckle when hitting the heat roll, and hitting up against the metal baffle. The two soultions to that are either to run in EIP mode or have your tech adjust the fuser speed.
