Sorry but no link so I can not see...
I am alsosorry but we can not trouble shoot the ink you purchased from another company in our carts. We can help you to understand if you are using our carts correctly or are using them incorrectly. But, you have filled them with an ink that we do not supply nor manufacture nor have any idea of its performance, etc and can not possibly advise or support.
We do manufacture a unique silkscreen positive opaque black pigment ink for film. We know its compatible with the R1400 printer. We can trouble shoot you with the use of our inks - but not with some other supplier's inks.
So, let me know how you filled the 1400 cartridges and I will let you know if there is something else you can do.
1) Which hole did you fill the ink into? The hole near the clip or the hole at the opposite end (not near the clip)?
2) Did you use the vacuum method or did you fill the ink using only a syringe (without first pulling a vacuum)?
3) When you inserted the carts into the printer - did you plug back both holes, or one hole. If only one hole - which?
