MXM450 - L4-02 code

[PASTech]

I'm guessing u haven't tried the sledge hammer technique...

What kind of environment is this machine it? I have heard of some machine in humid environments causing problems with the motors getting jammed from gummed up toner even in the motor themselves.

However sound like you have a board problem more than a Drum motor lock except for a broken toner auger which throws a loop into my statement about it being a board problem.

Weird problem.

Hope you figure this one out soon, I am interested in how it all gets fixed.

We just ordered another PCU and the EEPROM. It should be here tomorrow. We'll see what happens.

I have the same problem going on with a mxm450 have replaced everything you did also with no luck, going to try dc power supply today, only thing I haven't tried, will post results.

Dc power supply didn't help, mine is definitely in the dv/drum drive, they are getting new machine so I'm done with it.

I have only solved by bulletin MFP-TB-290 or replacing the main drive unit. DV leaks out and finds it way to the main drive unit.
