Troubleshooting a 240.84 Service Error Code

Issue description

When you print from the multipurpose feeder (MPF) and it runs out of paper, the printer registers a 240.84 service error code instead of prompting it to load the MPF tray.


A possible cause of this issue is due to the MPF media present sensor being dislodged or not in It's correct position as shown in the image below.

(A) ‑ MPF media present sensor in correct position

(B) ‑ Dislodged MPF media present sensor




Use a spring hook, or comparable tool,to pull the dislodged MPF media present sensor back into its correct position (C).

Did this resolve the issue?

Issue resolved

See next step.


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.


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.
