R1900 refillable cartridges available?

Are refillable cartridges to fit the R1900 still available? I could not find them searching IJM. I know it is an old printer, but mine is in great shape. Thanks!

You’re right, they’re missing. They used to be there but hard to find. Now they’re missing entirely. Hopefully it’s just an oversight. If not, you can use R2880 carts and just swap the chips over. Or 1430 carts. The cartridge body is the same.
