Rubber band

This a common problem on RISO RP3100, the rubber band that allows the master to be removed breaks because of the deterioration of the rubber. 
I found an old explanation from PrntNow

The tab taped in place
Comparison between ink tubes E on the left, GR on the right
E series inks also come with this nozzle in place, pull it out with pliers


Suggested printing settings, .2 layer height, no raft, no supports, infill doesn't really matter, but I leave mine at ~25%.

This tab allows E-Series ink to be used in GR machines, just remove the RFID sticker on the ink tube, and double sided tape the tab into the same "quadrant" where the sticker was.  This allows the machine to recognize the ink tube as a color ink tube.
