All iPF Models with an HDD---E602-401A Error Code
When an E602-401A Error occurs, the Service Manual suggestion is to replace the HDD.
However, there have been cases reported from the field that this error code is not cleared after the HDD has been replaced.
Note: When E602-401A occurs, ensure that a brand new, Canon issued service part HDD is used.
Never use an HDD that has been previously installed in another printer.
Procedure for replacing an HDD:
Whenever an HDD or the combination of the main controller PCB, HDD harness and HDD are replaced
together, boot the printer up in Service Mode and perform board replacement first (CPU for Main Controller
PCB, MC for M/C Relay PCB).
After this step is completed, turn OFF the printer and reboot into Service Mode again.
Turn printer OFF once more and turn printer ON in user mode. This will ensure that the HDD errors are cleared.
Note: There is no need to initialize or clear any error code while in Service Mode.
The printer is designed to auto clear errors when entering Service Mode. Also, the new HDD is automatically formatted when the printer is turned on after replacing it.
