Automatic reset bizhub 4050

[Bot]

Hello, I have a problem with the 4050, namely the machine resets itself every 9-10 minutes, it does not display any message, no error after the post is reset. I uploaded the latest firmware, changed the setting of Power Saving and nothing helps, the problem occurs on several machines, please help

Hi, access the service menu and check the error list.

The problem is she has no errors, it just resets without any message

Unplug network cable, will it restart?

It makes no difference whether it is connected or not

Have exactly the same Problem here with my Bizhub 4050. It restarts several times an hour. sometimes without any action, somethimes wen you push a menu button after some waiting time - and sometimes when you start a copy.

Do you have any ideas inbetween what it might be? The MFP was a few month not in service due to corona, no idea if it startet already before. Or might it be some issues with the Puwer Supply? some leaking capacitor or thinks like that?

Seems to me as it is a serial failure :-(

ADDITION: I already have tried with / without LAN cable, on another circuit / Mains, already plugged out the Fax-module - it didn't change anything. No Errors Recorded, just as if the power is disconnected for a few milliseconds, then it starts up completely normal again... The point of the reboot is not provokable by any action, it's just a feeling that it occurs more often during an action like start Copy or adjusting something in the user Menu... but ist also occures if you leave it für 15 minutes alone

I wonder if it may not be a power supply failure...

I see you have write "have tried with / without LAN cable" but i had a similar case with LAN cable and was the IPv6 of client enviroment.

Leave a door open and check if is works for more than 15min.
Check the history for error codes even if it does not display it could still be logged if its a controller error.
Do you hear the relays on the power supply click on and off when it restarts. If that is the case its probably the power supply or even the fuser.
Or does it restart without the power supply loosing power?

Ditto on error history, some E301 may be logged. I would try HDD format at first.

[Phil_bizhub]

does a relay have to click if the fault is in the power supply? The way I see it, the control unit has its own outlet on the PSU. Is it possible that this connection port z. B. has a defective capacitor or similar.
It already seems to be an absolute serial failure of the device? I noticed a comparative error with the corresponding Lexmark devices?

No not necessarily.

unfortunately the power supply did not help, I am looking for more

Oh , okay, thanks for the feedback, did you exchange it?

yes i did. I also replaced the HDD, the problem is still there

[Bix]

Hi, have you noticed any problems with the display (operator panel)? Often in this model they fail and create strange errors.

[allan]

Did you check the error log?

[Phil_bizhub]

Sorry, i was knocked out for a few days - no corona ;-) Now I'm back with my old issue... at least every ten minutes this Printer resets inbetween.
How do i get to the error codes at this machine? Counter >00 >01 doesn't get me to a service menue...

I already formatted the HDD without effect

When it resets i definitels don't hear a relay klicking, just som knocking of a speaker like switching of a transistor radio...

When I try to check the firmware in the menu, it just shows bars !?

Thanks a lot for your help in advance

Kind of a shot in the dark but it might be worth hooking it into an uninterruptable power supply, just to remove electrical noise as a factor. Then maybe try swapping the RAM? Just because it's incredibly easy and at least with PCs faulty RAM can cause any number of weird random problems... After that I think that poking around with a multimeter would be your next task, I would preface that by disconnecting optional accessories and seeing if the behavior changes. Fair warning I'm still closer to 'PC tech' than 'copier tech' so this process does come from that background and is potentially biased towards that mindset. Good luck.

[Phil_bizhub]

I already tryied it on a completely other circuit, like in another building, because i had some issues here recording to electrical noise.
As i'm klicking frequently through the Menue for minutes then i had the effect, that i regognized it was freezing just 1 second before it rebooted - but anyway it doesn't get me any further...
Does anyone know, where this ugly lexmark laser trashcan with a bizhub display has its Memory? somewhere around the HDD? or in the Displayunit? Somehoy everything is different to "kormal" and genuine bizhub machines...

I don't have KM docs so hard for me to be very specific, but typically it would be on the control board correct? If you have silk screens and teardown guides for these devices it should be in there but I can only access user level stuff from their website.

Interesting news:
I've let it just run... the Time between the "boot-ups" is exactly 9:14 min:seconds with the subtraction of the time til the software is loaded up i think it might be exactly 9 Minutes.
So i definately do NOT think that it is any kind of Memory fault or has to do sth. with the PSU.
I checked all counters für energy saving etc. but no one of them has anything like 9 minutes....
So Bizhub Specialists - any guess? is there any kind of timer that can cause a reboot or do anything that might bring the system to reboot?
The time doesn't change, no matter what i do - i can Copy - scan - klick to every menue and changes values - when the 9 mins are over - hard reset...

Did you check this? Also turn off any power saving mode and test. Those aren't really Bizhubs, more Lexmarks. They can perform but are tricky to persuade.

[Phil_bizhub]

I checked all the Power saving options
- there are no "9 minutes" or alike
- the options are all switched off or i have changed it in anyway
- if it were an objective power saving counter, it might have not startet counting while I'm active "playing "with the display or switch off 10 seconds after a print-job

can you imagine some other "occult" counters? is there some possibility to do a very hard reset?

Does this machine has gut a "real" service menu`like real bizhubs or only the few points behind the admin password area?

Maybe I missed something but just to be sure we're covering all the bases... Does it print? Can you get it to run any sort of job before the reset? Just a passing thought but what if we're too focused on power aspects and there's just an actual component trying to POST (power on self test, idk if that term is used with copiers) that is failing and causing the reset. Like the fuser is having a really hard time reaching temp and the controller\engine board soft resets during the process? Definitely an interesting problem

[Phil_bizhub]

Absolutely no failure, scan - Print - copy... everything perfekt. How do I get to an error - log in this machine?? does it have a real "Error - log"
Is it typical for these models that they do a reset instead of showing a failure / code and switches to a save -error -mode?

I tried to do some googling for you but the closest I found to any sort of reports\logging was print reports and idk how useful they would be.

I suspect the answer you're looking for could be found in the service manual if any of our friends on here happens to be able to get their hands on a copy, I found it for sale a few places 12$-14$ if you think it's worth the shot.

Here are the locations of the print reports if you wanna take a peek at them just for the hell of it.

[Print Reports]
To display: [Utility] - [User Settings] - [Scan/Fax Settings] - [Print Reports]
Print a TX report, RX report, and activity report.

Tanks for your engagement! I printed the logs as described by you, but there's nothing that has to do with the 9 min rebooting problem - and after all i changed all the time-depending values...

i will also google a little bit more tomorrow...

[tsbservice]

Do you have service manual?

[allan]

Wonder if its not failing at some sort of NVRAM backup procedure.

[Phil_bizhub]

SOLVED! - a little bit ,-)

The System has got a D-Sub 9pin connector tor use with a gprs Gateway to CS-Remote-Care. The gateway was not connected anymore because the printer moved to another office...

If this little box is not connected, the Printer will restart every 9 minutes - think it's some kind of handshake / keep alive impulse?

I think the easiest way to keep the system running (now that it changed its Home and it is not connected anymore to the CS Remote Network is to keep the GPRS - Gateway connected without the SIM-Kard installed and without GPRS Antenna (don't want it to send...)

Has anyone an idea how this "implant" can be removed sustainable without that creepy hardware trash workaround?

It might be the heartbeat setting in CS remote care. It's turned on by default and can be set between 1-256 minutes. Check the number it's set to under Communication interval. If it's set to 9 then that's the issue.
