I have an Epson WF3520, which is a three in one type (not that anyone uses Fax these days, which is an indication of how long I’ve owned it). I’ve always used aftermarket cartridges with no trouble. It uses separate cartridges for each colour. Cheap as chips to run. The postal delivery service from the company I use is extremely quick.
If you looked up “Internet” and “Ink” you might find them.
