I have a 4345 printer, obviously, that will not eject legal size paper or print duplex. All other functions appear to work perfectly.
The paper stops in the top cover area of the feed system, between the reversing separation-guide assembly and Reversing assembly.
I have swapped the following assemblies with a fully functional mfp:
reversing separation-guide assembly
Reversing assembly
Power-factor-correction (PFC) power supply
Engine power supply
and finally the DC controller
The error is consistent: "13.33.00"
When performing a maual sensor test, PS109 responds the same on both the functioning and non-functioning MFPs.
I just don't know what else to do.
