How are compatible cartridges and original cartridges different?

Compatible cartridges are specifically manufactured to meet or exceed Original Equipment Manufacturer (OEM) specifications. These cartridges offer a high standard of quality, reliability, and offer high-quality printing results. Compatible and generic cartridges are brand new cartridges, containing only new components, and are an economical alternative to expensive brand-name cartridges and supplies, which allow the consumer to enjoy big savings over brand-name cartridges and supplies. The use of compatible or generic replacement cartridges does not void the printer's warranty.

What are the advantages of using compatible cartridges?

Our professionally manufactured cartridges go through a rigorous testing & QA process, to ensure there is no difference in quality from genuine cartridges. Remanufactured cartridges are also environmentally friendly. Instead of sitting in a landfill, the cartridge cores are recycled and reused after going through our stringent remanufacturing process. All this, at significant savings!

Will compatible or remanufactured cartridges void my printer’s warranty?

You may be worried that the use of compatible or aftermarket printing supplies will void your printer's warranty. The use of's printing supplies will not affect your printer’s warranty. Your printer warranty cannot be voided because you select compatible products unless the manufacturer can prove that the compatible product caused direct damage to your printer. In cases such as this, the manufacturer may choose not to repair your printer but your warranty would remain in effect for all other warranty issues.
