2 | Hold the MPF tray media flag to cause the indicator light to switch ON. The light ON would indicate media is present. Does the light turn off and on? | The sensor is functioning properly. See next step. | Contact Lexmark support for further diagnosis. |
3 | Does the media flag move freely and with little resistance? Does the light switch OFF without media being present or loaded into the tray? | Continue testing to see if the error returns. | Try to push or pull the flag downward into its socket (fulcrum, pivot) to snap the sensor arm back into place. |
