Frequently Asked Questions

Is there any difference between ink and toner cartridges?

Any tips on storing my unopened ink cartridges properly?

You can maintain the quality and composition of your unopened ink cartridges by making sure they aren't exposed to harsh light sources or extreme temperatures.
