Code: E240-0000
Description: Controller communication error
A sequence error with the controller occurred.
Remedy: [Related parts] - Flexible Cable between the DC Controller PCB (UN04/ J112) and the Main Controller PCB (UN81/J7001) (Unit of replacement: CABLE, FLAT) - DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY) - Main Controller PCB (UN81) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY) [Points to note at work] When checking the harness/cable or connector, perform the following work. 1. Disconnect and then connect the connector to check that there is no bent pin and cable disconnection. 2. Visually check that the harness is not caught or open circuit. 3. If there is any error, replace the corresponding harness/cable. [Remedy] Perform the following in the order while checking whether the error is cleared. 1. Check the harness between the DC Controller PCB and the Main Controller PCB. 2. Turn ON the power, and check if the initialization is executed at startup. 2-1. If the initialization is not executed, replace the DC Controller PCB. 2-2. If the initialization is executed, replace the Main Controller PCB. [Reference] 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

Description: Reader backup error
Reading error was detected when the Controller IC of the Main Controller PCB read the Reader backup value in the Flash PCB.
Remedy: [Related parts] Flash PCB (UN96) [Remedy] Perform the following in the order while checking whether the error is cleared. After performing the remedy, enter the value of the service label again. 1. After executing COPIER> FUNCTION> CLEAR> R-CON, turn OFF and then ON the main power, and check whether the error is cleared. 2. After replacing the Flash PCB, reinstall the system software using SST or a USB memory.

Code: E248-0002
Description: Reader backup error
The Controller IC of the Main Controller PCB failed to rewrite the Reader backup value in the Flash PCB.
Remedy: [Related parts] Flash PCB (UN96) [Remedy] Perform the following in the order while checking whether the error is cleared. After performing the remedy, enter the value of the service label again. 1. After executing “COPIER> FUNCTION> CLEAR> R-CON”, turn OFF and then ON the main power, and check whether the error is cleared. 2. After replacing the Flash PCB, reinstall the system software using SST or a USB memory.

Code: E280-0004
Description: Scanner Unit communication error
1. The CIS was not connected. 2. A CIS other than that for iR-ADV C250/C350 was connected.
Remedy: [Related parts] - Flexible Cable between the Scanner Unit (CIS01, CIS02/ J911) and the Main Controller PCB (UN81/J8101) (Unit of replacement: CABLE, FLAT) - Scanner Unit (CIS01/CIS02) (Unit of replacement: CONTACT IMAGE SENSOR ASSEMBLY) - Main Controller PCB (UN81) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY) [Points to note at work] When checking the harness/cable or connector, perform the following work. 1. Disconnect and then connect the connector to check that there is no bent pin and cable disconnection. 2. Visually check that the harness is not caught or open circuit. 3. If there is any error, replace the corresponding harness/cable. [Remedy] Check/replace the related parts. [Caution] The parts numbers of the Scanner Unit are different between iR-ADV C250 and C350.
