Firmware Problem !

Hi i've just updated my Km 5430DL printer firmware from Konica Minolta website and rebooted printer. After i rebooted to printer there is nothing on the lcd menu now. Lcd menu is blank.

Status displays that Port is busy.After i restarted printer and pc nothing changed.

What happened to this printer ? I fullfilled the same things when i was starting to update firmware as guide shows . but there is still blank screen on the lcd menu.

    Thank you very much for your helps nightangel.i m surprised that i take answer on time.

    I would like to say i solved my problem but i m still in trouble with this machine.

    i used v2.0.7 version for update from Konica Minolta website.I m trying to update firmware again but printer is not communicating with pc. I removed driver and reinstalled it again but driver doesn't detect to printer. therefore i can't install driver to pc . I tried another usb and another pc but no avail.

    it continuous to show blank screen )=

    thank you my friend i think you are right i could be rebooted my printer early.

    the printer status was showing that port was busy when i rebooted it . i waited 10 - 15 or 25 minutes and thought that firmware had completed because i waited so much.. then i rebooted printer when it was still in blank screen.

    i have done all the things as guide shows. but there is something important thing that which is missing in that guide. it doesn't shows that how much time i have to wait and what happens at the end of this process when firmware is updated.

    now sellers advise to me that change mainboard and it costs 350 euros )= it isn't fair.

    Thank you so much for your helps.I appreciated you my friend.

    i had read that guide thousand times before updated my printer.Every step had completed with success as i saw in guide.

    I want you to know that firmware programme showed that update completed then reboot your machine. it went good on pc screen but printer ):

    My friend my printer is new and i printed only one thousand print.After that it showed toner measures low on the lcd screen.I had no enough money to buy original cartridge so I sent printer to refilling centre they sent back it with full measure.Because at first lcd menu showed all the toners %100.And i took perfect images.After i closed and opened printer it showed wrong measures and said install yellow toner.

    Then i decided to use firmware procedure when i saw it at KM wesite.I completed procedure with success as guide shows.

    But lcd was still blank and yellow. I waited approximately 20 minutes nothing changed.After i rebooted printer it lost communication with pc.

    Now printer isnt in guarantee.)))= I don't know what to do. Any advise ?

    I have the same problem( march 2009). It appear to me that this is not accidental because you seems to follow carefully the given instructions. Have you solved this problem ?
    Is there any solution given by Konica Minolta commercial supports ?
    ( sorry for my poor english )

I'm from germany. A few minutes ago the same desaster happened to me. Because the updater showed "reboot the printer", i did so, but then the printer lcd left blank, and in this moment I remembered that the display had indicated "still busy". The updating was still working in the moment I put the printer off. I think there is no chance to repair this by yourself. No firmware, no connection between pc and printer :'(

What version firmware you have v2.0.7 ?
Try to update firmware again and read the instructions one more time. Try reboot holding stop button down

    Try restarting this printer with cover open, then it wount start completly and maybe then it communicates with computer.
    Did I understand it right, that printer LCD screen is blank all the time?
    maybe its a LCD problem, does the buttons work? if you press select 3-4 times the printes should print conf, demo or stat page ?

    Ok, I did a little more research, you have to try all interfaces (lpt, usb, ip/web) if non works, then the printer controller FW is damaged, and you have to take youre printer to service.
    You may have to replace mainboard or interface board, beacause as far as i know there is no way to restore old firmware.
    may it be that you rebooted the printer to early, before it was finished.

  • Anonymous Dec 10, 2007

    i havent read the update manual in 2.0.7, i read it 2.0.8 and there was in bold text: that the display will show update completed, when succesfully upgraded and then its OK to reboot the machine. i'm not 100% how long it take to update, in smaller machines it takes sometimes 10-15 min, before this operation is completed sucsessfully.

    this mainboard cost really that much. maybe you cant tell them, that its just not working, and you can get it fix under warranty or maybe they can find used mainboard or a new printer.

    sorry, thats the way it is.

  • Anonymous Dec 10, 2007

    well, i suggest talk with service, and ask them nicely to get it done under warranty. Because toner refilling and firmware isn't related. so, the warranty doesn't cover any image related problems, but you have electrical problem, mainboard failure, you dont have to tell them, that you did FW update, just tell them, that one day printer LCD went blank and its not working anymore. Or ask them to look for a used mainboard. or you can get a little discount, if you give them this printer for spearparts, or by a little cheaper printer (MC 2550/ C10)???
