What is the best humidity range for printers?

  1. 10% to 20%

  2. 25% to 50%

  3. 50% to 75%

  4. 75% to 90%

The correct answer is: 25% to 50%

The best humidity range for printers is typically between 25% and 50%. Maintaining humidity within this range helps prevent issues such as paper jamming and misfeeds that can occur when the air is too dry or too humid. Low humidity can cause paper to become too dry and brittle, leading to issues in feeding and printing. Conversely, high humidity can lead to moisture being absorbed by the paper, which may cause it to stick together, curl, or jam in the printer. Thus, keeping the humidity levels moderate helps ensure optimal printer performance and longevity.
