Although counterfeit print cartridges may look like genuine HP print cartridges, they don’t provide you with the high print quality, proven reliability, and consistent yields you have come to expect from HP products.
The potential risks of using counterfeit print cartridges include poor quality print-outs, reduced page yields, print cartridges which fail prematurely or do not work at all, printer damage which may require repair, interruption of printing infrastructure and workflow, as well as potential invalidation of hardware warranties. Poor or inconsistent print quality is a primary indicator of non-original products.

(Investigations and actions have occurred on every continent except Antarctica.)
