3800 ink set is not designed for printing on plain paper. Doing a nozzle check you with plain paper you can tell how the darkest black looks like.
It is understandable one doesn't like to make his computer a Christmas tree by hooking up unnecessary hardware. If you print just a few text document and don't want to have another printer, get some light weight inkjet paper, I mean the cheapest that they don't dare to name it photo paper. They should work well with photo black, not sure if they work with matt black. Once involve a ink switch, it is totally waste of money.
One problem being these paper is single sided, the non-coated side are usually not bright white.
