Got these with some other stuff a while back and I’m not going to use them. Box was opened to check contents, but all ink bottles are still sealed in plastic.

I have no idea if this will work with your printer, so on this one I simply can’t accept returns.

Here is what I did find though , but this is from a search and by no means a guarantee it’ll work on your equipment.
