All laser printers use a drum coated with a photo-conductive medium that charges as the drum rotates. A laser beam removes this charge as it touches the drum, then the toner draws to places on the drum that still have an electrostatic charge, coating the drum with the print for the page. Resetting the drum counter on the OKI Data laser printer allows you to have a correct count of pages the image drum printed after you replaced the drum. The image drum on the B4200 and B4300 printers, for example, should last about 25,000 pages, although this number can vary due to the paper type you use, humidity and temperature.
