Code: CD40
Description: Toner bag full
Remedy: (1) Check the toner bag. • Is the toner bag full? (2) Check thetoner bag full detection sensor (S11). • Is the tone full detection sensor working properly? • Is the connector not disconnected? (3) Check the used toner transport motor. • Is the used toner transport motor driving? • Does the pulley beside the motor become heavy when it is turned toward the direction of arrow (counterclockwise)? (4) Replace the LGC board. (5) Release the status counter. • Turn the power ON while pressing both the [0] and [8] keys. • Press the [START] key after inputting [476] with digital keys. • Change the status counter "1", "2" or "3" to "0" and press the [SET] or [INTERRUPT] key ([CD4] released). • Check if the copier becomes to a standby state normally when power is turned ON again. • In case that the used toner transport motor does not drive or [CD4] is not released when power is turned ON again, do the above procedure after manually turning the pulley beside the motor toward the direction of arrow (counterclockwise) several times.

Code: CD50
Description: Web motor signal path abnormality
Remedy: (1) Check if the connector of the web motor and connector pins are not disconnected. (2) Check if the harness at the fuser unit is not open-circuited. (3) Check if the connector of the LGC board and connector pins are not disconnected. (4) Check if the harness between the connector of the LGC board and the fuser unit is not open circuited. (5) Replace the LGC board. (6) Replace the fuser unit.

Code: CDE0

Code: CE50
Description: Temperature/humidity sensor abnormality: The output value of the temperature/humidity sensor is out of the specified range.
Remedy: Is the connector CN338 on the LGC board or the connector of the temperature/humidity sensor (S7) disconnected? Is the harness between the LGC board and the temperature/humidity sensor disconnected? → YES → Connect the connector securely. Replace the harness. NO 1. Check the connection of the KEY board and DSP board. 2. Check the connection of the DSP board and LGC board. 3. Replace the temperature/humidity sensor. 4. Replace the LGC board.

Code: CE90
Description: Drum thermistor abnormality: The output value of the drum thermistor is out of the specified range.
Remedy: Is the connector CN337 on the LGC board, or the connector of the drum thermistor disconnected? Is the harness between the LGC board and the drum thermistor (THM5) disconnected? → YES → Connect the connector securely. Replace the harness. NO 1. Replace the drum thermistor. 2. Replace the LGC board.

Code: CF00
Description: Belt escape unit home position error detection: The belt escape unit does not leave the home position when the Knurled belt motor has been driven for specified time. [MJ-1029]
Remedy: Check the Knurled belt home position sensor (PI28). Does the sensor operate normally? → NO → Replace the sensor. YES Is the wiring between the finisher controller PC board and Knurled belt motor (M13) normal? → NO → Repair the wiring. YES Is there any abnormality in the belt escape mechanism? → NO → Check the assembly and repair the mechanism. YES Does it improve when the Knurled belt motor (M13) is replaced? → NO → Replace the finisher controller PC board. YES End

Code: CF10
Description: Undefined error code processing: If the engine of the equipment judges that a code (command) other than the defined error codes is sent from the finisher, it regards this as a CF10 error.
Remedy: (1) Is the error recovered when the power of the equipment is turned OFF and then back ON? (2) If not as in step 1, check if the LGC board and IPC board are connected correctly. (3) If the error has still not been recovered in step 2, check if there is any defect in the LGC board, IPC board or finisher control board. If not, replace the LGC board, IPC board or finisher control board.
