Ink marks on trailing edge

I’m getting ink marks on the trailing edge of Type 5 paper on a 3880 while doing the GO coat. Attached is a scan of an image with the marks. Any ideas?

The paper appears to be curling upwards and hitting the print head. When your environment is very dry (low humidity), paper has a tendency to contract. You can either carefully bend the paper backwards by rolling it from diagonal to diagonal (careful not to damage it or dog ear it) - or you can increase the humidity. You should not be printing with an Epson below 35% rH. In any event - quite a striking image! Sorry that the print head struck it… Let us know if these suggestions remedy.

Here is info about back-curling/flattening the paper before printing: http://www.inkjetmall.com/tech/content.php?148-Flatten-Curled-Paper-Before-Printing

In addition to making sure the paper corners and edges aren’t curled towards the print side before printing, you can also clean the printer’s capping station, wiper blade and bottom of the print head to remove gunk that can get transferred to the paper during printing (manual cleaning procedures can be found here: http://www.inkjetmall.com/tech/content.php?133-Printer-Cleaning-and-Preventative-Maintenance), as well as raise the printer’s platen gap.
