The tampering of any Rockstone Power product by any person or people, other than by an Rockstone Power representative, voids all warranties and releases Rockstone Power from all liability. Rockstone Power's liability hereunder shall be limited to replacement or reimbursement as stated above. This warranty is exclusive and in lieu of all other warranties, expressed or implied.
STMC Standardized Products
Most of our suppliers of remanufactured and compatible cartridges are now STMC Qualified. This means better quality and less defects and returns to deal with. You can purchase from us with confidence.
STMC stands for Standardized Test Methods Committee. This global committee was formed to find and promote standardized test methods for the printer cartridge industry. Standardized test methods are defined from ISO, ISTA, and ANSI standards.
A company that is STMC certified is one that has had their employees successfully trained by an authorized trainer in these test methods, attests to using these test methods, and has purchased the correct test equipment. By purchasing STMC certified products you can be assured that you will receive the highest levels of performance, reliability and quality with each cartridge.
