Ganson Manufacturing and Quality Control Process

• Our cartridges use the Patented ZeroTwist™ Technology. Canon© has begun an aggressive campaign of litigation against toner remanufacturers, resellers and their customers. Anyone not using ZeroTwist™ gears may face the threat of legal action. There are three types of cartridges OEM, ZeroTwist™ and ones that are in violation of Canon�s patent.
• Cartridges are built using brand new cores. The casing, toner hopper and waste collector are cleaned with compressed air and wiped down with a lint free cloth.
• The drum is replaced with a New Long Life or OEM drum.
• EVERY gear, screw, and spring are inspected and replaced as needed.
• The Wiper Blade, Doctor Blade, Primary Charge Roller (PCR) and Magnetic Roller are replaced.
• Premium seals are used to secure leak free usage.
• The Toner hopper is filled to the top. All of our toner exceeds OEM standards.
• Print testing occurs on each finished cartridge. Each sample page is inspected for gray scale quality. 
• 1% of each model�s production is stress tested. We print continuous pages at 18% coverage until the cartridge is empty. The cartridge is disassembled and inspected for imperfections.
• We drop test .5% of finished cartridges. The cartridge is dropped eight times per corrugated box side. The corrugated box is opened to verify fitness for use on our packed cartridges.
