Anyone even know of a shop that has used this defense successfully?
It's been talked about in some shops I talk to, but nobody I know has ever gone this route. Ever.
Its my understanding that a Roland printer recognizes 3rd party ink and does more head cleanings thus throwing your ink into the waste bottle faster.
I always love it when someone quotes this act. Below is taken directly form the link supplied. Notice it says personal use i.e. personal, family or household purposes.
I have never heard, seen, or met anyone who has successfully used this act to get a warranty enforced by a COMMERCIAL printer manufacturer. The act is to protect home users against companys like HP requiring that they use their inks. This does not protect commercial grade printers that we use.
If you want to void a warranty and go by this act, feel free.
If you are beyond the warranty and print enough to warrant the costs, third party inks may be an option for you.
Just my 2 cents.
From the http://en.wikipedia.org/wiki/Magnuson–Moss_Warranty_Act :
A "consumer" is a buyer of consumer goods for personal use. A buyer of consumer products for resale is not a consumer.
A "supplier" is any person engaged in the business of making a consumer product directly or indirectly available to consumers.
A "warrantor" is any supplier or other person who gives or offers a written warranty or who has some obligation under an implied warranty.
A "consumer product" is generally any tangible personal property for sale and that is normally used for personal, family, or household purposes. It is important to note that the determination whether a good is a consumer product requires a factual finding, on a case-by-case basis. Najran Co. for General Contracting and Trading v. Fleetwood Enterprises, Inc., 659 F. Supp. 1081 (S.D. Ga. 1986).
