Can a product's warranty require you to use only the maker's own brand of parts, like printer ink, to stay valid?

Generally no, unless the maker gives you those parts for free.

  1. Yes, any other brand voids it
  2. Generally no, unless they're free ✔
  3. Only for the first 30 days

Why: Under federal warranty law, a maker can't require specific parts or services to keep coverage, unless it provides them free or gets an FTC waiver. A part that actually causes damage is a different story.

Huh, didn't know that: Whenever there's a warranty, the law says it must be available for you to read before you buy.
