7-18Routine Maintenance7Replacing Toner Cartridges• Condensation may form in and on a toner cartridge if it is brought into an environmentthat exposes it to sudden changes in temperature and/or humidity. If you move the tonercartridge to a location that is warmer or has higher humidity, leave the cartridge in thenew location for 2 hours or longer without opening the protective bag to allow it to adjustto the new temperature.• Be sure to use new toner cartridges before the expiration date indicated on the package.• Keep the toner cartridge away from products that generate magnetic waves, such as adisplay or computer.Storing Toner CartridgesBe careful of the following points when storing a new toner cartridge or handling atoner cartridge that has been taken out of the printer for maintenance or moving theprinter.IMPORTANT• Do not take a new toner cartridge out of the protective bag until it is ready to be used.• When you take the toner cartridge out of the printer for servicing the printer or otherpurposes, place the toner cartridge into the original protective bag, or wrap it with a thickcloth immediately.• Do not place it vertically or upside-down. Store the toner cartridge in the sameorientation as when installed in the printer.• Do not store the toner cartridge in a place exposed to direct sunlight.• Do not store cartridges in a hot or humid place, or a place where the temperature andhumidity can change significantly.Storing environment temperature: 0 to 35°C (32 to 95°F)Storing humidity range: 35 to 85 % RH (no condensation)• Do not store the toner cartridge in a place where corrosive gases, such as ammonia, aregenerated, or where a considerable amount of salt is contained in the air, or where thereis a lot of dust.• Keep the toner cartridge out of the reach of small children.■ CondensationEven within the storable humidity range, water droplets may develop both inside andoutside of the toner cartridge due to the difference in temperature. The development ofwater droplets is called condensation. Condensation will adversely affect the quality of thetoner cartridge.
