    c454 quick on/off reset not possible

    Hello everyone, I was always helped in this forum after usually long nights of trial and error. I thought I might give it another shot before throwing out my current printer. It's a c454e, bought secondhand a true working horse until yesterday. The printer was in "sleep-mode" when I sent a print over the network. Instead of printing the pdf the printer froze. I then hit the green button to see if it was somehow stuck sleeping but nothing happened. I then switched off the power and switched back on, the printer starts, the display turns on, the two grey symbols show up. However no KM logo, the sound appears and after a few seconds the printer turns off where immediately it turns on again and the same procedure starts all over. I first thought I might be able to reset it by hitting the cancel button while turning it on, no chance. I unplugged the hard drive, no chance. I even checked the RAM sticks for damage, nothing. All I can see on the board are two red lights that turn on, when it's turned on and shortly after turn off again. I'm no expert but I have some capabilities. I got the printer some time ago, didn't pay much but would be very sad to throw it out. You never miss something until it's gone... Has anyone experienced the same problems? And maybe knows a simple remedy? Thank you very much in advance!

    Nothing too scary. You need new SSDb(not expensive) and firmware. However if you are not tech you probably should find one able to purchase the part and do the repair. While back cover is off I would recommend measuring backup battery as at that age and model they're real pain in the arse when fail. Anything measured below 3 volts DC with machine turned off and 5 minutes passed is bad sign.

    Thank you for your quick reply! So it's the ssdboard OR could it be the battery? The battery reads at 3.22V when unplugged for 5mins. Then I guess it must be the board, right?

    I would try to flash firmware first. Second thing would be to disconnect the HDD and see if it starts. Can also try to do a trouble reset by holding down the reset key while turning, black dot top right corner, wait a while and "trouble reset" shows on screen, touch , then turn off and on with main switch.

    When you get machine back working you will know bad battery if all counters are wiped out to 0. If counters are ok then battery is ok. But at some point that battery will fail as I'm seeing a lot lately.

    Re: c454 quick on/off reset not possible

    Sounds promising. I'm haviong trouble to find the firmware, I understand it doesn't get uploaded anywhere and has to be purchased? For the trouble reset: What do you intend by the button in the top right corner. I have tried the regular reset on/off with the yellow cancel button. Is there another way of doing it?

    Ok I tried that again, really doesn't work. I also know what you intended by the black dot. It shows up but then the machine turns off immediately and turns on again. I'll try to flash the FW, if you have it could you send it by PM? That would be very helpful, thanks! If that doesn't work I'll have to get a technician to take a look at it. Given the age of the machine and the counter stats it's questionable whether that still makes sense....

    As I've already said you need new SSD board, without that your machine would be boat anchor forever.

    You'll get more luck asking for firmware if you're a contributor, you'll likely need the service manual, make sure when requesting firmware that the printer model is specified exactly (c454 is different to c454e).
    I think there's already a post with firmware too...

    Sounds like you need to change some parts there before you do anything or you can make things worse.

    Good luck ����
