Remedy: Check the combination of the firmware. Use SIM49-1 to perform the firmware version-up procedure again.
Code: A0-20
Description: Machine level error (CTL detection)
Causes: Inconsistency between the MFP firmware version and the EEPROM data version
Remedy: Check the combination of the firmware.
Code: A0-21
Description: Machine level error (PCU detection)
Causes: Inconsistency between the PCU firmware version and the EEPROM data version.
Remedy: Check the combination of the firmware.
Code: A0-22
Description: Conflict firmware and EEPROM data version (SCN-MFP)
Causes: Inconsistency between the SCN-MFP PWB firmware version and the EEPROM data version.
Remedy: Check the combination of the firmware.
Code: C1-10
Description: Main charger trouble (Monochrome)
Causes: Open circuit or short circuit of the main charger (Black) output
Remedy: 1) Check & Remedy Use SIM8-2 to check the output of [GB-K]. If the leakage noise or the flickering on the screen of the panel is detected; (1) Abnormality of the charger (BK) -> Remove and insert the charger (BK) or replace the charger (BK). (2) Imperfect insertion of the charger (BK) -> Remove and insert the charger (BK). (3) Abnormality of MC-K harness (Transformer B801 of the high-voltage MC PWB) -> Remove and insert MC-K harness or replace MCK harness. (4)Abnormality of GB-K/DV-KCMY wiring -> Check GB-K/DV-KCMY wiring./Replace. (5) Abnormality of the developing unit (K/C/M/Y) -> Insert and remove the developing unit./Replace. (6) Abnormality of the high voltage MC PWB spring contact (GB,DV). -> Check the high voltage MC PWB spring contact. 2) Check & Remedy Use SIM8-2 to check the output of [GB-K]. If the leakage noise etc. is not detected; (1) Charger (BK) not inserted. -> Insert the Charger (BK). (2) Disconnection/ breakage of MC-K harness (Transformer B801 of the high-voltage MC PWB) -> Insert the harness./Replace. (3) High MC PWB trouble. -> Replace the high MC PWB. (4) PCU PWB trouble -> Replace PCU PWB.
Code: C1-14
Description: Main charger trouble (Color)
Causes: Open circuit or short circuit of the main charger (Color) output
Remedy: 1) Check & Remedy Use SIM8-2 to check the output of [GB-C/M/Y]. If the leakage noise or the flickering on the screen of the panel is detected; (1) Abnormality of the charger (C/M/Y) -> Remove and insert the charger (C/M/Y) or replace the charger (C/M/Y). (2) Imperfect insertion of the charger (C/M/Y) -> Remove and insert the charger (C/M/Y). (3) Abnormality of MC-CL harness (Transformer B901 of the high-voltage MC PWB) -> Remove and insert MC-CL harness or replace MCCL harness. (4)Abnormality of GB-CMY wiring -> Check GB-CMY wiring./Replace. (5)Abnormality of the high voltage MC PWB spring contact (GB,DV) -> Check the high voltage MC PWB spring contact. 2) Check & Remedy Use SIM8-2 to check the output of [GB-C/M/Y]. If the leakage noise etc. is not detected; (1) Charger (C/M/Y) not inserted. -> Insert the Charger (C/M/Y). (2) Disconnection/ breakage of MC-CL harness (Transformer B901 of the high-voltage MC PWB) -> Insert the harness./Replace. (3) High MC PWB trouble. -> Replace the high MC PWB. (4) PCU PWB trouble -> Replace PCU PWB.
