Question

Printers

Yuzveri screwed up and dumped refilled and unrefilled cartridges in one pile)) in fact, can they be somehow distinguished without a printer?

Answer 1

Weigh. The lightest among identical models are empty. A lot of people have kitchen scales these days.
And so an experienced enikeischik, who holds a cartridge not for the first time, can usually weigh and determine in his hand.
If you shake the cartridge, then in any case it is felt: something is floundering there or not floundering.
