We always start with an original, brand new, HP toner cartridge. We then upgrade the standard toner with TROY MICR Toner Secure, which is The Worlds Most Fraud Resistant MICR Toner - it bleeds red when chemical alteration is attempted! Starting with an original HP cartridge is vital to the security, quality, and reliability that our customers depend on.
