First of all check that the ribbon core is correctly placed with the notches fitting on the Green wheels. If th ribbon coe is not secured the wheel will not turn and no ribbon will be detected. If your core is too short and with no notches, you'll have to glue a pice from another core an create a notch.

Use an appropriate Ribbon.
Check that the slits on the ribbon detection is not full of dirt.
check that your ribbon motor parameters are correctly set.

You have to set the ribbon type to be "non-transmissive" for black transfer film.
To set the ribbon type, turn the printer off. Then press and hold the "feed" and "pause" buttons while turning on the power. The printer will now be in diagnostic mode - you can page through the menus until it says "ribbon type"
Pick the correct type and press the "pause" key to save the value. Then turn off the printer and turn it on again normally. The ribbon error goes away.

Ribbon error message is displayed when the rotation of the ribbon spindle is not performed or not correctly detected. This can be due to various factors.
- The ribbon roll is not correctly fitted to the spindle.
- The sensors detecting the rotation are out of order or completetly filled with dust or grease.
In this case clean the sensors.
Another reason may be due to Direct thermal printing with a ribbon mounted.
