error 355 canon ir adv 6255

[blackdevil]

I have a one machine that works properly and another one that has 355 error

I borrow the 4 counter pcb from good machine and installed to other one and get the same error

now I put back the counter pcb’s to the good machine but unfortunately
the good running machine got 355 error also

now 2 of my machines have 355 error

There might be a clear 355 error in service mode.

How did the error first appeared.
Your issue could be speed license . The main controller and the speed doesnt match .

Try clearing err .

And make sure about the 4 boards and main controller are in the correct machine .

When you change the main controller you have to keep all the small chips from that machine and move them to the new board. Swapping then around is the worst thing you can do because now you have a mismatch with the chip ID vs. your serial number board information.
