Hi I do not cut on our CJV 30, but ours would do the same thing when printing. It seems to be the chip readers for the ink. The cartridges come out a little through vibration. You have to tap them back in. We took a board about 2" wide x 3/4" and put foam tape on one side. Then we clamped it across all 8 ink cartridges, so that they cannot pop out. It is a bit of a pain when changing ink, but worth it as It does not fall into local.
