FO-4400U FO-CS1 3. Installing the printer cartridges (Toner cartridge: FO-50ND) (Drum cartridge: FO-47DR) Follow the steps below to install or replace the toner and drum cartridges. • The initial starter toner cartridge included with the fax machine can print approximately 3000 letter-size pages (4% coverage of each page; continuous printing). • The replacement toner cartridge (FO-50ND) can print approximately 6000 letter-size pages. • The drum cartridge (FO-47DR) can print approximately 20,000 let- ter-size pages. 1 Press the cover release to open the print compartment cover. • Caution! The fusing unit inside the print compartment becomes very hot during operation. Be careful not to touch the inside of the compartment. 3 If you are replacing the drum cartridge, remove the old cartridge and dispose of it according to local regulations. 4 Remove the new drum cartridge from its packaging. Insert the drum cartridge into the print compartment. • Caution! Excessive exposure to light will damage the drum cartridge. Install the cartridge promptly after removing it from its packaging. • Make sure the drum cartridge is inserted in as far as it will go. BLUE 2 If you are replacing the toner cartridge, remove the old cartridge and dispose of it according to local regulations. Go directly to STEP 6 if you are only replacing the toner cartridge and not the drum cartridge. • If you are replacing the drum cartridge but not the toner cartridge, remove the toner cartridge and place it on a sheet of paper. GREEN 5 If you are installing a new toner cartridge, remove the new toner cartridge from its packaging. Remove the tape from the cartridge and then open the cartridge handle so that it stands straight up. 6 Shake as indicated by the arrows to distribute the toner evenly within the cartridge. • If the toner is still lumpy after shaking, the gears in the cartridge may make a noticeable sound when the print compartment cover is closed after installing the cartridge. This is normal and does not indicate a problem. To make the cartridge more compact for disposal, press the buttons on the ends of the handle and fold the handle down. 1 - 5
