imageRUNNER ADVANCE C2030/C2020-Prevent E020-0360/ E020-0391/ E020-03b1
Measure to prevent E020-0360/ E020-0391/ E020-03b1 error codes due to electrostatic buildup on the black toner sensor during shipment.
Error codes E020-0360/ E020-0391/ E020-03b1 may occur due to electrostatic buildup on the black toner
E020-0360: Low density of the target during patch detection.
E020-0391: The average value of the detected inductance sampling value is equal to or higher than the
E020-03b1: Error in detecting the delta T/D ratio (T/D ratio detected by the ATR Sensor is equal to or lower than the specified value).
A false detection may occur due to an electrostatic charge within the light-emitting/-receiving section of the black toner sensor , which is located in the area where it receives toner from the toner bottle leading in too much toner adhesion. Because of this, toner supplied to the black developing assembly becomes insufficient resulting in an error.
After replacing the Toner Feed Assembly, please review the additional steps to perform on page 8 of 8.
