Routine Maintenance

•Do not attempt to disassemble or modify the toner cartridge.
•If you expose a toner cartridge to rapid changes in temperature, droplets of water 
(condensation) may form on the interior and exterior of the cartridge. If a new toner 
cartridge that has been stored in a cool location is going to be installed in a warm area, 
leave the cartridge for at least one hour without opening the protective bag to allow the 
cartridge to adjust to the surrounding temperature before opening the bag.
•Be sure to use new toner cartridges within the expiration date indicated on the package.
•Keep toner cartridges away from products that generate magnetic waves, such as the 
computer or monitor.
•Toner cartridges are magnetic parts. Do not bring toner cartridges near floppy disks, disk 
drives, or other magnetic-sensitive devices. Doing so may cause data corruption.
Storing Toner Cartridges
Be careful of the following points when storing a new toner cartridge or handling a 
toner cartridge that has been taken out of the printer for maintenance or moving the 
printer.
IMPORTANT
•Do not take a new toner cartridge out of the protective bag until it is ready to be used.
•If you take the toner cartridge out of the printer to remove a paper jam or service the 
printer, place the toner cartridge into the original protective bag, or wrap it in a thick cloth 
immediately.
•Do not stand it on its end, or turn it upside down. Store the cartridge in the same direction 
as when it is installed in the printer.
•Do not store the toner cartridge in a place exposed to direct sunlight.
•Do not store the toner cartridge in a hot or humid place, or a place where the 
temperature and humidity can change significantly.
-Storage Temperature Range: 0 to 35°C (32 to 95°F)
-Storage Humidity Range: 35 to 85%RH (non-condensing)
•Do not store the toner cartridge in a place where corrosive gases, such as ammonia, are 
generated, or where a considerable amount of salt is contained in the air, or where there 
is a lot of dust.
•Keep toner cartridges out of the reach of small children.
•Do not store toner cartridges near floppy disks, disk drives, or other magnetic-sensitive 
devices.
■Condensation
Even when the humidity is within the storage range, water droplets may form on the inside 
or outside of the toner cartridge due to temperature differences with the surrounding air. 
This condensation will have a bad effect on the performance of the toner cartridge.
