Patented Anti-Tamper Security: Prevent check fraud by utilizing an extra layer of security to your printed checks. TROY’s MICR Toner Secure releases a red dye whenever chemical alteration is attempted, voiding the check. Precision-Matched: TROY’s unique manufacturing and testing process has produced a precision-matched toner for each specific printing machine. This helps maintain optimum laser printer performance. Prevent Toner Scraping: Toner scraping attempts are commonly used to commit check fraud. Because of the high adhesion of our toner, this type of fraud is nearly impossible to commit. MICR Readability: Printed checks using TROY toner result in high readability and legibility that not only meets but exceeds all ANSI and ABA banking standards. HP OEM: In 1993, TROY became authorized by HP to enhance HP Printers and consumables for use in secure check and document printing. TROY is now the only HP OEM partner authorized to modify HP printers and supplies for secure print applications.
