What happened?
The printer is displaying the message: RPM of fan not in range!
Error name: Fan RPM out of test range
Error code: #10127
Issued if the RPM of any of the printer's fans is not within their limits of use when measured, during the calibration wizard.
Starting from firmware 1.7.0, this error replaces Fan RPM not in range #10122 (SL1/SL1S)
How to fix it?
The SL1/SL1S has three fans:
- The LED cooling fan (indicated in the picture by a purple arrow on the left).
- The right blower fan (indicated in the picture by a green arrow in the middle).
- The filter fan (indicated in the picture by a blue arrow on the right).
If the warning appears, please follow the maintenance steps for the fan that generated the issue: SL1/SL1S maintenance. When doing that, also check the cable connections of the fan to the mainboard.

Run the Selftest once again. For SL1, navigate to LCD menu -> Settings -> Recalibration; for SL1S, navigate to LCD menu -> Settings -> Calibration -> Selftest. In case the fan also fails during the self-test, switch the connection of two of the fans, and see if the warning will be transferred to the new fan. If the error is transferred, the fan that had the warning originally may need to be replaced.
