Every microMICR MICR Toner Cartridge is manufactured at our own factory in the USA from a brand new Original Equipment Manufacturer's cartridge from Hewlett Packard, Lexmark and Samsung using special MICR toner developed and tested specifically for each model printer, retaining the original components, and keeping the OEM factory seal intact. This assures the highest consistent quality of MICR printing, minimizing bank check rejects as well as toner leakage problems common with recycled toner products.
