&quot;if you are required to return the cartridge&quot;<p>I&#x27;d love to see the exact legal language that even specifies that condition &quot;required to return&quot;.<p>After all we can assume that most people don&#x27;t do that or actually that those who don&#x27;t return the cartridge almost certainly suffer no legal jeopardy for that inaction. If you are required to do something by a contract, then you would expect some degree of enforcement when the contract terms haven&#x27;t been met. My guess is that Lexmark can&#x27;t show any action they take for cartridges not returned.<p>I&#x27;ve often noted how companies that sell laser cartridges will give you a free label to UPS the cartridge back to them. They cloak it as &quot;recycling&quot; but it serves two purposes. It gives them a free cartridge to refill but it also takes away a cartridge that could be used by a third party that would a sale from the company.
