How to install an OPC Drum?
Before proceeding with the installation of a new OPC drum, you must turn the laser printer off, and then wait a few minutes for the internal components to cool.
In the first step, you must open the front cover of the laser printer, and then remove the installed toner cartridges by pulling each cartridge slowly towards you.
After that, you must carefully pull the waste toner container towards you to remove it from the main unit, and then grasp the handle of the used OPC drum. Now, you must pull the used OPC drum towards you until its top handle is accessible, and then use the top handle to remove the exhausted component.
In the next step, you must take the new OPC drum from the protective package, and then remove the transport spacers and the protective paper. Once the new OPC drum is prepared, you must slide it into the laser printer until it clicks into place, and then remove the four dummy caps from the toner cartridge slots. After that, you must reinstall the toner cartridges and the waste toner container.
In the concluding step, you must close the front cover, and then turn the Laser Printer on.
