I am getting a ribbon fault error on Datamax ONeil M Class Mark II Printer. What can I do to resolve this issue?

Check inside the green guide (sensor) for pieces of label. That will block the sensor. If the sensor is reporting a thickness which is double (250) what you expect, then that is definitely the issue.

If you open the case there is a sensor that detects whether the head is opened or not that is connected to the open and close lever. Sometimes the tab that blocks the sensor when it is closed get out of alignment or comes loose or the sensor is jarred loose. Make sure the tab breaks the beam.

Re-calibrate the printer. If still not working, take out the ribbon assembly by removing 3 screws and check the sensor ( "L" shaped plastic glass). If still not working, buy a new ribbon assembly.

Position fault or Out of stock when the printer is loaded with paper stock can usually be solved by calibrating the printer.

Press & hold the FEED button. Let the printer cycle 8-10 times. Should feed to the right position and say Calibration Complete in the window.

Hope this solves your problem.

The error is indicating that it cannot calibrate the media. Try holding in the feed key for approx 10 seconds and see if it will calibrate. Experiment with the position of the media sensor. It will slide horizontally.
