That trick for studioprint doesn’t work for the 11880 (I tried it at Black Point Editions). It’s different scale printer . . .
If those carts work, the head design is about the same as the x900-levels so the curves for the x900 printers that are at piezography.com should work with some small amounts of linearization. Now that there will be a lot of orphan 11880s out there I’m thinking of supporting it . . . For now though, all I can say is it should work! If you get a perfect nozzle check and run some linearization charts that I can validate were printed and read-in correctly, I wouldn’t mind running some lins for free. We could post the .quads as beta for others interested in the 11880 system. Not sure how much interest is there but this could gauge the interest-level.
Keep ahold of your old OEM chips and carts though just in case. also, this is going to take a metric “” ton of piezoflush to clear the lines of stain (especially Y). You’ll need two sets of carts. It might be worth it to simply buy a new damper assembly now to clear the stain from that little beast. If it hasn’t been replaced already, the damper assembly is due for it.
ps: Due to the under-printing nature of Piezography, this should fix (somewhat) the ink-starvation issues in large dark black prints that plague the 11880.
