ITS A FAULT FROM MY PART TO PARTICIPATE IN THIS THREAD.

I think that no one in this forum - you or anyone else - is at fault for this thread (unless the arse that that shorted the pins lurks in this forum ). I wish I had a cent for everythime I'm trying to find out what's wrong the machine when the operator is witholding information that could be helpful!

It's always nice when a techie asks for help and there's someone reading that can give a hand - and you did nicely!

Burning smell!!!
Check PWB-M board
it is mounted next to the power supply
There must be physical damage (burnt component on the board)

hi friend,
Yes, most probably PWB-M faulty.I'am sorry for the technician.Check for any blown ICPs on PWB-M.This board ( A parameter chip seemingly DS2432 on MECH.CONTROL PWB holds life of IUs etc.,) relates directly to most problems related to P codes,Motors,clutches,timings etc., The burning Smell may related to some blown ICP.Carry out replacement test of PWB-M in another machine.PLEASE Involve that user/operator also in this procedures as atleast here after he may not short something in an elect. gadget.
Thanks & Goodluck

hi to all...

didn't realy understand some of the previous messages posted on this tread , but anyways... down to what realy matters, WHICH IS HELPING EACHOTHER AND LEARNING WITH EACHOTHER.

We have replaced the PWB-M board, machine starts like it used to, back to normal... but now when we print/copy, paper comes out completely white with no printed area. we will figure it out eventually ourselvs, but again, to whom is willing to be helpfull and kind, we will appreciate any help given as it will shorten down the time the machine is non-operative.

Please keep nonproductive coments to yourselvs, as they are absolutely useless and are a waste of pixels.

many thanks

hi Friend,
You might already trouble-shooted the complaint.If you are unable to under stand some previous posts(non productive according to your goodself),then let me explain.No body blamed you, but the operator/user for shorting contacts(which should not me done in any gadget, unless you know the possible out come).More over this MATTER reported lately in the thread as you are unaware of it,which invited sudden response from all. Me, also doubted unknowingly that its 'smell' of corona arching.
Anyway,please check HV-Unit(I wrote in my first reply) and if good then power supply also as ,We are not familiar with a shorting incident and what damage it can do & also What if your operator/user had done some extra engineering in it and hiding from you?

Hi once again to all!

ok, we now have the machine printing! BUT... after a couple of prints, it stops . a tech freind of mine, told me to try it with new firmware, but i don't have the frimware (and i don't know which is the latest version) or the cygin program to put it on the CFcard, therefore i would appreciate if someone could send me a copy of both the firmware and program, and also the process of instalation.

MANY THANKS!
