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:
Remedy: EEPROM 1 Check that the EEPROMs installed in the control PWB are correct and, if not, use the correct EEPROM for the model. 2 If the EEPROM data are currupted, contact the service support. Control PWB Replace the control PWB and check for correct operation.
Code: 0180
Description: Machine number mismatch Machine number of control does not match.
Causes: Data damage of EEPROM
Remedy: 1 Confirm the machine data for the control 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.
Remedy: Replace the control PWB and check for correct operation.
Code: 0800
Description: Image processing error JAM010X is detected twice.
Causes: Control PWB
Remedy: Replace the control PWB and check for correct operation.
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:
Remedy: Battery (Control PWB) 1 Make sure that the back-up batteries on the control PWB are not short-circuited. 2 If the same C call is displayed when power is switched on and off, replace the back up battery. 3 If communication error (due to a noise, etc.) is present with the RTC on the control PWB, check the PWB is properly grounded. Control PWB Replace the control PWB and check for correct operation.
Code: 1010
Description: Lift motor error After cassette 1 is inserted, lift sensor does not turn on within 10 s. This error is detected five times successively.
Causes:
Remedy: Bottom plate elevation mechanism in the cassette Check to see if the bottom plate can move smoothly and repair it if any problem is found. Connector cable or poor contact in the connector Reinsert the connector. Also check for continuity within the connector cable. If none, replace the cable. Lift motor and connect right PWB (YC9) Connect right PWB and control PWB (YC65) Drive transmission system of the lift motor Check if the gears rotate smoothly. If not, grease the bushes and gears. Check for broken gears and replace if any. Lift motor Replace the lift motor. Connect right PWB Replace the connect right PWB. Control PWB Replace the control PWB and check for correct operation.
