Sounds like your printer's head is hitting the paper. Are you using heaving (310 gm) fine art paper? You may wish to check your printer settings, under printer properties (in Windows). When using my Pro-100, I need to check the "prevent paper abrasion" box, in Maintenance-Custom Settings to keep the printer heads from hitting the leading edge of thick papers. Also, it never hurts to pre-curl the leading edge of your paper. I hope this helps.
