[Misc] Strange Issue with a C224

[Kazzy]

Hello Gents, today I have a strange issue I have not yet encountered. I have 2 Bizhubs at home, both running SW 7 and recently one started to show a bit of humor, She stopped rotating periodically the drums when being idle. I have never (yet) encountered such a strange problem. The funnier thing is she only stopped doing it about a week ago. At first I thought it was just me being me however, upon further inspection it did indeed turn out that one of them does not rotate the drums periodically as she should. I work till quite late hours and often would hear them in the other room running the drums late at night until a week ago. I turned off the other machine and placed a high end Mic towards the "faulty" one for 24hrs to ensure it wasn't just me being me...and I was correct, no spikes, no drum rotations whatsoever. I did repeat the same test on the other unit and I could clearly tell thr other one is actually rotaing drums as it should. I'm quite baffled as both are set with the very same settings, the supposed "faulty" one shows no signs of any drum flat spots. Hence my question...what in the bloody F is going on?, is this a sign of a potential SW corruption?, HDD issues?, Main Board staring to go funky?, any way to force the drum rotation setting off and then back on in the Service Menu? Or is this just a Bizhub Humor type of a thing?. I take good care and respect all of my equipment, both printers always get an end of week cleaning so if one is starting to show signs something might need to be replaced I would like to know as they are getting older and parts might be harder to find in the future so I would like to try and get to the bottom of this, and yes I did try a soft reset already.

Did the sleep or energy save settings get changed? If not mistaken when this machine goes to sleep nothing turns. And in energy save mode only the fuser rotates periodically so roller doesn't get a flat spot. Think rotation of all components start when machine is woken up.

Upon checking, all the settings are like the other one which does rotate the fuser. What I do not understand is the fact that it was all fine till last week as I mentioned. Then she just decided to stop any rotations whatsoever while she's idle.

Sounds like the 1 that "the drums are not turning" is behaving as it should be and the other machine is not.

Normal conditions are as follows:

- After a period of inactivity the machine goes in to sleep mode - this means the machine will go silent until it is used again, nothing will turn.

You don't want the fuser turning when you are not using the machine as it will cause premature failure of the fuser.

I suggest setting a sleep timer on both machines for maybe 20 mins.

Well I was told the fuser has to turn to prevent flat spots, infact I asked about this before I bought the other one. We had issues with an older model due to...flat spots on the fuser. Hence I wanted to ensure it all works fine on my newer machines. So I believe the one which does rotate them does the right thing and the other one doesn't. How are flat spots ment to be prevented if the machines does not periodically rotate the fuser ?. Infact I asked a KM Engineer who was here to service them few months ago about this rotation thing and he confirmed its ment to "rotate periodically and the fuser is designed to withstand it and many more rotations throughoutits life". He said the "issues start when the machine fails to rotate it periodically".

Re: Strange Issue with a C224

if the fuser stays hot and does not rotate yes there can be a flat spot but if its in energy save or sleep nothing should turn during those times. afaik

What monthly volume is going through the machines?

Also a C224 is not a newer machine, its 11 years old.

They are personal machines retired from a company that barley used them. Monthly volume for both is about 200 sheets. That's A3 and A4 combined. Most likely around 150 A4s and 50 A3s at best. They are newer to the point they are reliable enough where I don't have to buy any expensive parts so far. A belt and a cleaning blade is gonna be due for the one that doesn't rotate periodically and thats about it. My house is pretty much a retirement home for old electronic equipment, ranging from a Commodore 64 to Windows Xp through Vista to 8.1 as well. I even have a Xerox 7142 here.
Small orders still come through for printing posters for lost animals however the largest one was just 50 A3s. So yeah 11 year old machines are more reliable than a C280 which I sold last month.

Fair, they are good machines anyway and consumable prices are low if you buy drum rebuild kits etc.

Re: things turning when you are not using the machine I wouldn't worry about it if it was me

Hmm thats strange then. On a side note I was once told that the large Accuriopress models, the older ones at least have an "auto seasonal mode" which is ment to rotate less certain parts during Spring and Summer months and rotate a lot more during Autumn and Winter months when they are idle. He explained it with a long soliloquy about expansion and contrast of fusers, drums and belts and something to do with thr climate etc. I don't know if its true but he has a mix of older and newer machines and has been pretty much servicing them by himself for thr past 12 years. Personally I never seen anything like this on any bizhubs.

production machines are a different animal, cannot compare to the tuxedos.

Fair enough. I could always swap the motherboards and see if that does something though I usually go by the rule
" If it ain't broke don't fuckin' fix it".

Just a fair warning, if you swap "motherboards" you may have 2 machines that don't work. Leave well enough alone. Perhaps update the firmware and that's it!

Both are running FW Version 7, did 8 come out already ?

I think you might be out of your depth here, if you start swapping boards around as said above you might end up with 2 broken machines.

They are not on firmware version 7, they are on function version 7.
