Description: Billing counting error The values on the main circuit PWB and on the engine do not match for any of charging counter, life counter, and scanner counter.
Causes: EEPROM. Main/Engine PWB.
Remedy: EEPROM 1. Check that the EEPROMs installed in the main/engine PWB are correct and, if not, use the correct EEPROM for the model. 2. If the EEPROM data are currupted, contact the service support. Main/Engine PWB Replace the main/engine PWB.
Code: 0180
Description: Machine number mismatch Machine number of main/ engine does not match.
Causes: Data damage of EEPROM.
Remedy: 1. Confirm the machine data for the main/ engine units by using U004. 2. If the serial number data of different models is alternately displayed, install the correct EEPROM in the PWB of the wrong serial number data. 3. Contact the Service Support.
Description: DMA error DMA transmission of image data does not complete within the specified period of time.
Causes: Main/Engine PWB
Remedy: 1. Confirm that the wiring connector is firmly connected and, if necessary, connect the connector all the way in. 2. If the wiring is disconnected, shorted or grounded, replace the wiring. 3. Replace the main/engine PWB.
Code: 0800
Description: Image processing error JAM010X is detected twice.
Causes: Main/Engine PWB
Remedy: Replace the main/engine PWB.
Code: 0840
Description: Faults of RTC (“Time for maintenance T” is displayed) [Check at power up] The RTC setting has reverted to a previous state. The machine has not been powered for 5 years (compared to the settings stored periodically in the EEPROM). The RTC setting is older than 00:01 on January 1, 2000. [Checked periodically (in 5- minute interval) after powered up] The RTC setting has reverted to a state older than the last time it was checked. 10 minutes have been passed since the previous check.
Causes: Battery ( main PWB). Main/Engine PWB.
Remedy: Battery ( main PWB) 1. Make sure that the back-up batteries on the main/engine PWB are not shortcircuited. 2. Reset Maintenance T by executing U906. 3. If the same C call is displayed when power is switched on and off, replace the back up battery. 4. If communication error (due to a noise, etc.) is present with the RTC on the main/engine PWB, check the PWB is properly grounded. Main/Engine PWB Replace the main/engine PWB.
