This is the genuine OKI fuser unit for the B721 series mono laser printer, part number 45435104. The fuser applies heat and pressure to bond toner permanently to the page, so it is a wear part with its own replacement cycle, separate from the toner cartridge. Fit a new fuser when the printer reports fuser life expired, or when toner smudges or lifts off finished pages.
