How do I install the OPC belt cartridge?

Open the front cover, release both belt cartridge lock levers by pulling them up, and remove the orange belt tension release pins from both sides of the OPC belt cartridge along with the protective sheet. Insert the OPC belt cartridge into the printer guides with the flat side facing you, then lock the belt cartridge lock levers and close the top cover. Be careful not to touch the green surface of the OPC belt or expose it to light for any length of time. (Page 1)
