Code: E744-4000
Description: Error due to the DC Controller not compatible with the model
The DC Controller PCB or the Main Controller PCB which was used with another model was detected.
Remedy: [Related parts] DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY) [Remedy] This error occurs only when replacing the DC Controller PCB. Perform the following in the order while checking whether the error is cleared. 1. Install the previously used DC Controller PCB (UN04) again. [Caution] If another error code is displayed after reinstalling the previously used PCB, refer to the appropriate error code. 2. If the error is not cleared although the previously used DC Controller PCB is installed again, replace it with a new one. [Reference] - DC Controller PCB does not have model information at the time of shipment. Model information is written in when the PCB is installed to the host machine. Therefore, the DC Controller PCB which was installed to iR-ADV C350 can be installed only to iR-ADV C350. - Before replacing the DC Controller PCB, back up the service mode data (approx. 2 min) and restore the backup data after the replacement so the data may be able to be protected. - Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP - Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
