The OKI 45103724 is the genuine clear image drum for OKI's five-colour production printers: the ES9541, Pro9541, Pro9541Ec and Pro9541Ev. These printers add a fifth clear station to the usual CMYK, which is used for spot gloss and protective clear coats. The drum is rated for about 20,000 pages, based on OKI's 5% coverage estimate, and is replaced separately from the clear toner, so you only change the part that has worn out. Genuine OKI consumables are designed for the printer's LED engine and help keep image quality consistent across long runs. Supplied as one original OKI drum unit.
