Problems in the main controller area.
The E355 error code is due to no communication between the Main-Controller board and the Serial Number board below it. The boards are connected by a 11 PIN yellow connector and cable. This yellow connector must be reseated on the new Main-Controller board when changed. The connector must be seated firmly on the board.
When this error occurs, you must go into Service Mode and clear the error code.
How to clear the error code:
1. Enter Service Mode: Press * Additional Functions, 2&8 simultaneously, then * Additional Functions again.
2. Then select the [COPIER] option. Under [COPIER], select the Function tab.
3. Under the [FUNCTION] tab, select the [CLEAR] option.
4. In [CLEAR] there is a selection E355-CLR. Select it and hit OK.
5. Reboot the machine.
If the error occurs again:
1. Make sure the connection is secure and tight to the Main-Controller board from the connector cable to the Serial Number board below.
2. Reseat the Main-Controller board into its slot.
3. Go into service mode and clear the error code as explained above.
* If the error still continues, you probably have a bad Serial Number board and it needs to be replaced.
E350 is soft ID PCB Faulty and E355 is counter pcb problem. Have you cleared the code in service, if COPIER>Function>CLEAR>E355-CLR], press the OK key to clear it
Replace the set of Counter pcb & Serial pcb for E355
check the conection between counter pcb & monitor pcb for E350
This fix will have to go through Canon. They will have to get a serial number and then send you out a Main Controller and Serial Number PCB as a set. I had this happen to me one time
