From around 2014 Epson started playing with the idea of user replaceable waste ink pads and moving to a chip to store the waste counter rather than leaving it in the printers memory. These products are known as “Maintenance boxes” and now make up a large part of the Epson printer approach to waste ink although it has been a long slog getting to the point they considered it necessary.
While many Epson printers now have these units, it’s important to check ahead if you’re buying a new printer. Some of the cheaper units, even Ecotank types, such as the ET-2820 still make use of an internal waste ink counter and porous pad assemblies that are officially not supposed to be end-user serviceable.
