Kyocera printer message: "Low temperature. Adjust room temp."

Quick answer

The room is too cold for the machine to operate within specification. Kyocera's documented action is to adjust the temperature and the humidity of the room. Worth knowing before a cold-garage or unheated-office machine is diagnosed as faulty.

Before you try the solution

  1. 1. Copy the complete message exactly as shown, including any code, letters, or punctuation the panel puts around it.
  2. 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
  3. 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.

If the error is still there

  1. 1Return to the screen or job that produced the message and check whether the code has cleared.
  2. 2If "Low temperature. Adjust room temp." returns, do not repeat a risky procedure. Record when it appears and check the documentation for the exact model.
  3. 3If the documented action does not clear "Low temperature. Adjust room temp.", contact Kyocera support or a qualified printer technician with the model number and complete message.
