Good afternoon with everyone, I have a problem with canon ir advance c7055 and c7065 equipment, it presents me with the error e355-0004, I am exchanging main controller boards, which I found in my stock, due to black screen problems, I found that one of them gives me the error e355-0004, but I don't have the information where the counter and serial pcbs would be located. You can provide me with some information on the location and detail of the counter and serial pcbs.

Thank you so much.
