We wanted to pass along some tips for handling your ink cartridges in the winter weather extremes as the cold temperatures can affect the cartridge. Store your current stock of ink cartridges away from exterior walls to keep them closer to room temperature. For cartridges that have been recently shipped, we suggest letting them slowly return to room temperature before they are used. If you have a cartridge that is not working properly, it is likely due to the temperature of the ink. Hopefully these tips will make the cartridges work correctly.
