Chapter 1414-29F-14-38[1] Waste toner detection windowThe detection method employed in the waste toner detection sensor is the magnetic detection method, instead of the often-used transmission detection system.Employing the magnetic detection method enables the sensor to detect correctly, even if a small amount of toner is left on the waste detection window.When tapping the window to remove the toner, do not tap it too hard.14.3.3.3.6 ATR Error (E020-XXXX) Display due to Dirt on ATR Sensor Window0014-8102imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+CauseThe waste toner may adhere on the ATR sensor window or the sensor shutter. As a result of that, it may be faultily detected as ATR sensor fault and trigger theATR sensor error (E020-XXXX).The detail codes (xxxx) are as follow: XXA0, XXA2, XXA8, XXA9, XXC0, XX10, XX11, XXDA.Filed MeasureClean the ATR sensor window and the ATR sensor shutter with the following procedure.1) Remove the ATR sensor from the main body.2) Press the plunger [1] of the ATR sensor lever solenoid in the direction of the arrow.3) Clean the ATR sensor window [2] and the ATR sensor shutter [3] with lint-free paper [4].F-14-3914.3.3.3.7 Power Supply Voltage Connector Error (E009-0000) Indication at Replacement of the DC Controller PCB0015-1271imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+CauseAt replacement of the DC controller PCB, the voltage cannot be recognized unless the jumper connector (J1152) is disconnected from the old PCB and connectedto the new one, resulting in power supply destination connector error (E009-0000).Remedy in the FieldAfter replacing the DC controller PCB, be sure to disconnect the jumper connector (J1152) from the old PCB and connect it to the new one.The destination and connectors specification are indicated below.[1][1][2][4][3]
