Initially, you must open the front door of your Lexmark C920 Color Laser Printer, and then open the internal cover. After that, you must unlock the exhausted photo developer by pushing its releasing lever up, and then pull the exhausted component along with the attached toner cartridge out of the laser printer. Now, you must unpack the new photo developer and a new toner cartridge of the corresponding color, and then remove the black protective sheet and the sealing tapes from the new components. In the next step of the replacement procedure, you must slide the new photo developer into the corresponding slot until it locks into place, and then close the internal cover. Once the internal cover closed, you must slide the new toner cartridge into the printer, and then turn the green lock lever of the cartridge to the left. Finally, you must close the front door of your Lexmark C920 Color Laser Printer.
