(6) Abnormality of the high voltage MC PWB spring contact (GB,DV). (5) Abnormality of the developing unit (K/C/M/Y) -> Insert and remove the developing unit./Replace.
(4)Abnormality of GB-K/DV-KCMY wiring -> Check GB-K/DV-KCMY wiring./Replace. (3) Abnormality of MC-K harness (Transformer B801 of the high-voltage MC PWB) -> Remove and insert MC-K harness or replace MCK harness. (2) Imperfect insertion of the charger (BK) -> Remove and insert the charger (BK). 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). Remedy: 1) Check & Remedy Use SIM8-2 to check the output of.Causes: Open circuit or short circuit of the main charger (Black) output.Description: Main charger trouble (Monochrome).Remedy: Check the combination of the firmware.Causes: Inconsistency between the SCN-MFP PWB firmware version and the EEPROM data version.Description: Conflict firmware and EEPROM data version (SCN-MFP).Remedy: Check the kind and the version of the firmware.Causes: Written ACRE board of the firmware that a model did not support MFP was connected.Description: Combination of firmware error between the SCN-MFP and the ACRE ASIC.Check the SCN-MFP PWB, and replace if necessary Check the scanner expansion PWB (ACRE), and replace if necessary. Remedy: Check connection of the scanner expansion PWB (ACRE).(garbled data) Scanner expansion PWB (ACRE) connection trouble. Causes: A decode error occurs while high compression PDF images are made.Description: Image data decode error (Scanner expansion PWB (ACRE) ASIC).Check the SCN-MFP PWB, and replace if necessary. Scanner expansion PWB (ACRE) connection trouble. Description: Image data trouble (Scanner expansion PWB (ACRE) ASIC).Check connection of the connector and the harness between the SCN-MFP PWB and the LSU PWB.
Frequency abnormality of picture transfer clock of SCN-MFP PWB.
