The result of the Encoder sensor test is only reported via the serial output and not via the

frontĆpanel. To perform the encoder sensor test, move the carriage  so that the encoder

sensor can detect the change in status. If the carriage is not moved at all, the Encoder Sensor

test will always fail. If the carriage is moved and ONLY the Encoder Sensor test fails, then you

need to replace the Carriage Assembly
