Description: Charger count error
Remedy: 1 Checking the machine serial no. on the main PWB The main PWB for the different main unit is installed Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct main PWB if the main No. differs 2 Checking the machine serial no. of the EEPROM on Engine PWB The main PWB for the different main unit is installed Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct engine PWB if the engine No. differs 3 Checking the main PWB The main PWB is faulty When the MAIN machine serial No. differs at U004, replace the main PWB and execute U004 4 Checking the EEPROM on Engine PWB The EEPROM is faulty In case if the machine serial No. registered in the engine PWB is different in U004, reattach the EEPROM on the engine PWB. If it is not fixed, replace the EEPROM and execute U004 After that, compare the setting value of the maintenance report output by U000 beforehand and the setting value of the maintenance report output after replacing the EEPROM, and change the setting value if it is different (Target maintenance mode: U053, U100, U101, U106, U140, U161, U464, U252, U034, U065, U066, U067) Then next, execute the following maintenance mode in order U119 (35 ppm model and faster) > U411 > U469[Auto] > U140[AC Calib] > U140[Calibration] > U412[Normal Mode](35 ppm model and faster) > U464[Calib](35 ppm model and faster) > U410 > U155[Calibration](Necessary to have an empty waste toner box) 5 Replacing the Engine PWB The engine PWB is faulty Replace the engine PWB
Code: C0180
Description: Machine serial number mismatch
Remedy: 1 Checking the machine serial no. on the main PWB The main PWB for the different main unit is installed Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct main PWB if the main No. differs 2 Checking the machine serial no. of the EEPROM on Engine PWB The main PWB for the different main unit is installed Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct engine PWB if the engine No. differs 3 Replace Main PWB The main PWB is faulty When the MAIN machine serial No. differs at U004, replace the main PWB and execute U004 4 Checking the EEPROM on Engine PWB The EEPROM is faulty In case if the machine serial No. registered in the engine PWB is different in U004, reattach the EEPROM on the engine PWB. If it is not fixed, replace the EEPROM and execute U004. After that, compare the setting value of the maintenance report output by U000 beforehand and the setting value of the maintenance report output after replacing the EEPROM, and change the setting value if it is different (Target maintenance mode: U053, U100, U101, U106, U140, U161, U464, U252, U034, U065, U066, U067) Then next, execute the following maintenance mode in order U119 (35 ppm model and faster) > U411 > U469[Auto] > U140[AC Calib] > U140[Calibration] > U412[Normal Mode](35 ppm model and faster) > U464[Calib](35 ppm model and faster) > U410 > U155[Calibration](Necessary to have an empty waste toner box) 5 Replacing the Engine PWB The engine PWB is faulty Replace the engine PWB
Code: C0350
Description: Panel PWB communication error (Electronic volume I2C communication error)
Remedy: 1 Reset the main power switch The operation of the operation panel PWB is faulty Turn off the power switch and unplug the power cord. After 5s passes, reconnect the power cord and turn on the power switch 2 Checking the connection The connector is not connected properly. Or wires are faulty Clean the connector terminal of the following wire and re-insert them If there is no conductivity, replace the wire Operation panel PWB - Main PWB Operation panel PWB - NFC PWB 3 Replacing the operation panel main PWB The operation panel main PWB is faulty Replace the operation panel main PWB 4 Replace Main PWB The main PWB is faulty Replace the main PWB 5 Replacing the NFC PWB NFC PWB is faulty Replace NFC PWB

Description: Communication error between the engine PWB and ASIC
Remedy: 1 Reset the main power switch The main PWB does not work properly Turn the power switch off and disconnect the power plug. Plug power code and turn power switch on in 5 second. 2 Checking the Engine PWB Connector or FFC is not secured. Wire, FCC or board is defected. Clean up wire terminal on the main PWB and insert the wire connector and connect FFC terminal again Replace or repair wire if problem is observed. Replace the engine PWB if the problem is not fixed.
