If you have purchased the compatible Linx 8900 ink or solvent empty cartridges, then you also need a clamp to help you tighten up the caps. Can we use the one for tight up Videojet or Imaje cartridges, sorry, we can’t. The clamp for Linx 8900 cartridges is with bigger diameter, which matches with the caps. Likewise to the clamp for Videojet/Imaje cartridges, this fits a smaller cap size.
You could tell the difference easily by have a look at below pictures.
