Without an example of exactly what the output looks like all we can do here is guess. Upload an image to imgur.com and post the link here.

One thing comes to mind. With most colour printers when you start to print a document you get to choose some options for this particular job. For any that are ONLY black ink jobs like text or line drawings, I always tell it to print Black ONLY for two reasons. BOTH of these are because the printer's default setting is to print using all colours, and BLACK in that mode means it will print ALL FOUR colours of ink. This wastes the three colour inks AND means that too much ink is used not always exactly lined up with each other so it can be a bit fuzzy. See if you can find the black-only printing option for text documents.

Next item is this, since some of your docs WILL have colour and need all four inks. Look through your manual for a maintenance process to adjust the ALIGNMENT of the ink nozzles. Many printers have a self-adjusting process you can trigger manually for this adjustment. It is to ensure that each colour of ink that is supposed to line up with the other colours actually does that.

Last thought is about paper. At one time you needed special ink jet papers to use such a printer, and you still need special paper for good PHOTOS. But these days for simpler jobs you should be able to use any good copier grade of paper, especially if the paper claims to be multi-purpose. But really cheap paper may NOT work well because it lacks a surface treatment that prevents ink from blotting.
