E020-01A9 Error Code.
For ATR control, the detected Toner/Density ratio exceeds the lower limit (3%) 3 times continuously for Yellow
The ATR Sensor and Patch Image Read Sensor both determine toner density. Depending on the density readings the copier will or will not add toner. Check the status of the Drum Unit under COPIER>DISPLAY>MISC>DRUM-LIFE. The Patch Image Read Sensor looks at a patch of toner that is generated on the drum for each colour and determines the amount of toner that is in the patch by the amount of reflected light. If the drum is not creating the patch correctly, the patch reading will be affected. Replace the Drum Unit if it is 80% of its rated life or higher. ..
