Having spare toner cartridges on hand is always a good idea, especially if you print often. But, if you don’t know how to store your toner cartridges properly, you could inadvertently destroy or damage your cartridges. We’ve put together a guide on how to store your toner cartridges correctly.

Toner cartridges can be stored for two years from the production date. To find the production date, have a look on the bottom or sides of the box your cartridge came in.

Keep the temperature low

Store your toner cartridges at or below room temperature. If you live in an area with very high summer temperatures, you should store your cartridges somewhere cooler (a colder storeroom or a room with air conditioning, for example).

Higher temperatures can cause the toner powder to melt inside the cartridge. Heat can also cause damage to the cartridge casing itself, melting and warping the plastic. This can also be a problem if you have a toner cartridge with a built in drum (like most HP toner and Samsung toner cartridges). Too much heat can cause the aluminium drum to warp, leading to poor print quality.

Keep it dry

Humidity and moisture are toner powder’s worst nightmare. Excessive moisture will cause toner powder to clump inside the cartridge and can lead to a whole host of issues, like uneven toner distribution and poor print quality.

If you live in an area with high humidity, it’s best to store toner cartridges in a room with relatively low humidity. Most modern air conditioning systems also keep the humidity in a room down, so store your toner cartridges in a room where the air conditioning is used.

This is especially important for those toner cartridges that do not have a built in drum unit, like Brother toner, as the toner powder is a more exposed.

Store away from direct sunlight

Keep your toner cartridges in a drawer or cupboard to keep them out of the sun. Sunlight can cause the toner cartridge casing to warp or melt. If the cartridge warps, it will not fit into the printer properly and may cause toner spills and other issues.

Leave the packaging on

Keep the toner cartridge in its packaging until you are ready to use it. The packaging is designed to protect the cartridge from direct light, dust and debris. If keeping your toner cartridge in the box takes up too much storage space, do not remove the cartridge from the sealed plastic bag and don’t take off the protective shipping covers.

This also protects the drum units from getting scratched or damaged, which could lead to grainy prints or lines on your prints, and keeps the chips on your toner cartridges clean.

Leave the lights off

If you are storing drum units or toner cartridges with built in drum units, make sure not to expose them to too much light. The drums are very photosensitive and too much exposure to light can cause them to not hold images properly when printing, leading to grainy prints or prints with missing sections.

We hope this helps you keep your toner cartridges in good working condition. If you have any questions about storing your toner cartridges or need any other help, please feel free to contact us.
