I'm not sure if it's the same on the Falcon as it is on the ValueJet, but that's a Print Feed Error meaning a couple of possible things.
1) The weight of the roll is too heavy for the feed mechanism to handle so when the motor tries to pull the media through, it can't handle the weight and just shuts down
2) Since it's used, the print feed motor might have just been bad.
Normally that error is related to scenario #1 on the ValueJet, but again, may be different. Ask RandyA on this forum. He works for Mutoh and might be able to offer some assistance.
