SHARP MX-3501N L4-31 Error code

[A\ztech]

Hi Guys been losing sleep over this machine, I replaced Both delivery fans and both PCSFM fans above the black hopper but machine still kicks up code. Did sim6-2 sometimes the delivery fans work and sometimes they don't. I have yet to see the PCSFM fans turn on. got a PCU board on order.
any suggestions would be appreciated.

There are a lot of possible problems. Look at TB MFP-SB-154, MFP-TB-361, TT-20097 and TT-062713_1 for more followup. Some other things to look at include the LSU cooling fan and the harness for the fans. Doubt if it is the PCU but I know that is one of the things to replace in the troubleshooting sequence.

Good luck.
