The remanufactured AstroJet Image Blaster inkjet cartridges from LD Products are guaranteed to meet or exceed the print quality of the OEM AstroJet Image Blaster inkjet cartridges. These remanufactured cartridges are OEM HP "virgin" cartridges (they have only been used previously for one cycle of service) that have been professionally remanufactured. We only choose virgin cartridges that are in perfect condition. We disassemble them, cleanse the inkjet cartridge chambers thoroughly, and flush any ink remnants with de-ionized cleaning agents. With an additional centrifuge evacuation, we eliminate any remaining excess particles and fluids. After a complete cleansing process, we fill the ink cartridges with the finest quality ink formulations. We then prime and weigh them for volume and set them overnight to be inspected. After a wide variety of tests such as placing them in vacuum sealed chambers for atmospheric pressure changes in addition to simulating other environments to ensure leak-proof seal integrity, we test the nozzle firing and quality according to strict testing protocols. A few of the criteria we evaluate are the optical line and color density, dry time, decap time and banding on various substrates along with the USPS Intelligent Barcode output of the product life cycle. Purchasing our remanufactured HP ink cartridges is an excellent way to save money without sacrificing quality. Our AstroJet Image Blaster remanufactured ink cartridges have a 'Two Year 100% Quality Satisfaction Guarantee'. The use of our remanufactured ink for the AstroJet Image Blaster does not void your printer's warranty.
