Just an update on this thread (and related to other small formats), we will be making new master and curves for the 1430 at some point soon. This may come in the form of a new driver that is for Piezography that brings the resolution and quality of all small formats up.
Related to cartridges:
We decided to come up with our own unique cart design with totally different air/liquid flow control and equilibrium. These carts will come out for all small format (besides the R1800s and R1900s) soon.
We hope they are well received.
