If you can, store your cartridges in your printer. Outside of a printer, ink cartridges can begin to dry out. If the printer uses a separate ink cartridge and printhead, the printhead can degrade if ink cartridges are not installed.
If your ink cartridges cannot be stored in your printer, please store them in an airtight plastic container, making sure to keep the nozzles upright. Make sure nothing touches the nozzles. Don’t store them in a bag as you risk damaging the nozzles. Ink cartridges can be stored at temperatures between -15°C and 35°C (5°F and 95°F).
If your toner cartridges cannot be stored in your printer, please store them horizontally in the original packaging they came in and seal the packaging as much as you can. Toner cartridges are much easier to store than ink cartridges as you don’t have to worry about ink or alcohol, and if stored correctly can last years on a shelf.
