Fujitsu Error Code 11.1 Explanation

When something goes wrong with your Fujitsu air conditioning unit, error codes will flash on the screen. However, you must first understand the error code description and what it signifies for your device until you can determine the specific source of the problem. We’ll walk you through the Fujitsu 11.1 error code fixes as well as how to apply them to resolve the difficulties in this tutorial.

Types Of Error Codes

When an incident arises when using the scanner, the Indicator light becomes red and a runtime error appears on the Number Screen.
  • For faults that are just transient, the letters “J” or “U” alternate with error messages.
  • For device problems, the letters “E”, “C”, “H”, or “L” display alternatively with an alert number.
Users can fix temporary faults, but device issues need a service specialist to solve. To remove a transient error, hit the [Scan/Stop] key or perhaps the [Send to] key while it is shown. When there are no papers ([Ready] state) in the scanners, the paper jam notification will erase after a specific amount of time has passed.
