SOURCE: error code 070020
From the service manual:
One of the Drop Detection errors has occured - or, during the Drop Detection no drop was detected.
Pen checking is set to OFF.
1. Perform the drop detect calibration
2. Troubleshoot the cartridges and the drop detector
3. If required, replace the service station
4. Check the cable assembly and the main PCA.
If you are inclined, I can upload the service manual for you which tells you how to enter the service mode and perform the drop detect calibration. Warning: If this is done incorrectly, it could render your machine useless so if you are not inclined to do so, hire a professional to do it. Otherwise let me know and I will upload the manual for you.
