Causes: The flash memory data read at the initial start-up is faulty
Remedy: 1 Resetting the main power The flash memory does not operate properly. Turn off the power switch and unplug the power plug. After 5s passes, reconnect the power plug and turn on the power switch. 2 Checking the main PWB The connector or the FFC is not connected properly. Or, the wire, FFC, the PWB is faulty. Clean the terminal of the connectors on the main PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace them. If not resolved, replace the main PWB.
Causes: 1. Continuous five times detection of no response from the device for 5ms or more on reading / writing. 2. Data read twice do not match continuous 8 times. 3. Writing data and reading data do not match continuous 8 times.
Remedy: 1 Resetting the main power The EEPROM on the Engine PWB does not operate properly. Turn off the power switch and unplug the power plug. After 5s passes, reconnect the power plug and turn on the power switch. 2 Checking the EEPROM on the Engine PWB The EEPROM is not properly attached. Reattach the EEPROM on the Engine PWB. 3 Replacing the EEPROM The EEPROM is faulty. 1. Print Maintenance Report at U000 beforehand. 2. Replace the EEPROM on the Engine PWB. C0180 appears when turning the power on. Execute U004 at that state. 3. Then, print Maintenance Report at U000. Compare the setting values with Maintenance Report printed before and change the different values. (Target maintenance mode: U051, U065, U067, U100, U101, U161, etc.) 4. Check the output image and adjust the image at U410, etc. if necessary. 4 Replacing the Engine PWB The Engine PWB is faulty. Replace the Engine PWB.
Code: C0160
Description: EEPROM data error
Causes: The data read from the EEPROM is judged as abnormal.
Remedy: 1 Resetting the main power The EEPROM on the Engine PWB does not operate properly. Turn off the power switch and unplug the power plug. After 5s passes, reconnect the power plug and turn on the power switch. 2 Executing U021 The storage data in the EEPROM on the Engine PWB is faulty. Execute U021. 3 Replacing the EEPROM The EEPROM is faulty. 1. Print Maintenance Report at U000 beforehand. 2. Replace the EEPROM on the Engine PWB. C0180 appears when turning the power on. Execute U004 at that state. 3. Then, print Maintenance Report at U000. Compare the setting values with Maintenance Report printed before and change the different values. (Target maintenance mode: U051, U065, U067, U100, U101, U161, etc.) 4. Check the output image and adjust the image at U410, etc. if necessary. 4 Replacing the Engine PWB The Engine PWB is faulty. Replace the Engine PWB.
Code: C0170
Description: Charger count error
Causes: 1. Errors are detected in both backup memory of the Engine PWB charge counter and main PWB charge counter. 2. Main PWB counter data and Engine PWB counter date are faulty
Remedy: 1 Replacing the main PWB The main PWB is faulty. Replace the main PWB and execute U004 2 Replacing the EEPROM on the Engine PWB The EEPROM is faulty. 1. Print Maintenance Report at U000 beforehand. 2. Replace the EEPROM on the Engine PWB. C0180 appears when turning the power on. Execute U004 at that state. 3. Then, print Maintenance Report at U000. Compare the setting values with Maintenance Report printed before and change the different values. (Target maintenance mode: U051, U065, U067, U100, U101, U161, etc.) 4. Check the output image and adjust the image at U410, etc. if necessary. 3 Replacing the Engine PWB The Engine PWB is faulty. Replace the Engine PWB.
Code: C0180
Description: Machine serial number mismatch
Causes: The machine serial Nos. in the main PWB and the EEPROM on the Engine PWB mismatch when turning the power on.
Remedy: 1 Checking the machine serial No. of 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. in the EEPROM on the Engine PWB The EEPROM for the different main unit is installed. Check the machine serial Nos of MAIN and Engine at U004, and install the correct EEPROM on the Engine PWB if the Engine machine serial No. differs. 3 Replacing 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 the Engine PWB The EEPROM is faulty. If the machine serial number on the Engine PWB is different at U004, reattach the EEPROM. If not repaired, replace the EEPROM on the Engine PWB. 1. Print Maintenance Report at U000 beforehand. 2. Replace the EEPROM on the Engine PWB. C0180 appears when turning the power on. Execute U004 at that state. 3. Then, print Maintenance Report at U000. Compare the setting values with Maintenance Report printed before and change the different values. (Target maintenance mode: U051, U065, U067, U100, U101, U161, etc.) 4. Check the output image and adjust the image at U410, etc. if necessary. 5 Replacing the Engine PWB The Engine PWB is faulty. Replace the Engine PWB.
Code: C0190
Description: Backup memory device error (Engine)
Causes: Data from the main unit IC cannot be read out at power-up
Remedy: 1 Resetting the main power The IC in the Engine PWB does not operate normally Turn off the power switch and unplug the power plug. After 5s passes, reconnect the power plug and turn on the power switch. 2 Replacing the Engine PWB The Engine PWB is faulty. Replace the Engine PWB.
