Description: Error in the developing assembly (toner fault: ATR error)
Indicates that the patch level is higher than the upper limit of the target although setting it as the minimum when initializing Yellow ATR.
Remedy: Clean the ATR sensor window. Check the mounting of the developing assembly. Check the ATR sensor open circuit. Replace the ATR sensor.
Code: E020-0011
Description: Error in the developing assembly (toner fault: ATR error)
Indicates that the patch level is higher than the upper limit of the target although setting it as the minimum when initializing Magenta ATR.
Remedy: Clean the ATR sensor window. Check the mounting of the developing assembly. Check the ATR sensor open circuit. Replace the ATR sensor.
Code: E020-0012
Description: Error in the developing assembly (toner fault: ATR error)
Indicates that the patch level is higher than the upper limit of the target although setting it as the minimum when initializing Cyan ATR.
Remedy: Clean the ATR sensor window. Check the mounting of the developing assembly. Check the ATR sensor open circuit. Replace the ATR sensor.
Code: E020-0013
Description: Error in the developing assembly (toner fault: ATR error)
Indicates that the patch level is higher than the upper limit of the target although setting it as the minimum when initializing Black ATR.
Remedy: Clean the ATR sensor window. Check the mounting of the developing assembly. Check the ATR sensor open circuit. Replace the ATR sensor.
Code: E020-0020
Description: Error in the developing assembly (toner fault: ATR error)
Indicates that the patch level is lower than the lower limit of the target although setting it as the maximum when initializing Yellow ATR.
Remedy: Clean the ATR sensor window. Check the mounting of the developing assembly. Check the ATR sensor open circuit. Replace the ATR sensor.
