Gripper arms

Gripper arms (which I think are synonymous with gripper fingers) are flat metal extensions attached to a bar beneath the platen.


Letterpress ink is pretty tacky and the paper can end up getting pulled away from the platen and sticking to the image. The gripper arms can be adjusted on the bar, and they hold the paper in place against the platen so this does not occur. Although my Pilot was missing its gripper arms when I purchased it, small images were not a problem. But when I started printing the houses on Sarah and Michael's baby announcement cards, I discovered that I really needed them. I got an incomplete set locally through a post on Briarpress and I got the rest of the parts from Dave Churchman; I believe he manufactures the entire set and sells them for about $100.
