I have a customer with a MX-4101N that's coming up with a L4-45 Code. the Service Manual (at least my version) is very confusing as to where the toner cooling motors are located. I don't know if any other techs have experienced this error before and if theres a common fan to cause this problem. The manual states this error is caused by toner cooling fan 1 or 2 (with 3 total). I believe ive looked at every fan in this machine and they are all rotating. Has anyone seen these spin but still not send the proper signal back to the PCU board? Or do these models have common bad PCU PWBs that cause this error code. Thanks in advance.
