I would be curious where a company like that gets their stock. Ricoh doesn't sell parts on the open market, especially not their toner. The toner may be old stock from a returned machine. Modern toner is fragile, meaning it has to be stored correctly, in the right temperature, or it will become unusable pretty quickly. Hardened toner is horrible to get out of a machine, often requiring a lot of very expensive parts to be replaced, like a several thousand dollar development unit.
