Re: How to identify my Bizhub C203 problem?
There are three things that can experience drive failure and not show an immediate effect:
1) toner add
2) developing agitation
3) waste toner system
if it sounds like it's coming from the back it's probably the waste toner system. Wow! You have a treat in your future! =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: How to identify my Bizhub C203 problem?
This series was bad for hardened toner clogging the supply tubes in the back, it could also be the transfer belt waste augers or related parts. Either way, this is not a task the average end user wants to tackle. This is hours of tear down, cleaning and re assembly. I would recommend having a Konica Minolta dealer quote a price for the repair, and then, if this is what the problem is, replace the MFP. EmujoComment

Re: How to identify my Bizhub C203 problem?
Record the sound to make sure we are going down the correct rabbit hole.
If its the waste toner transport you are going to be thrown into the deep end.
Very fixable there is just a 1000 bits and pieces you need to remove to get to the problem it takes almost an entire day to do.
So i really hope for your part its not that.WhateverComment

Re: How to identify my Bizhub C203 problem?
Each time i've had this clicking caused by toner clogging in the waste pips etc I write the machine off, it is simply not worth the time & effort to repair such an old machine.
Now the weather has got hotter (UK) this problem starts appearing!
Nightmare job!
Let us eat, drink, and be merry, because tomorrow we may die!

Re: How to identify my Bizhub C203 problem?
Few cans of beer, good music and no one interrupting you you'll be done in 4-6 hrs. All depends on your photo-memory in your brain.
Good luck and hope it is not the same as in the video below. The sound was very ratchet like type. Nylon gears skipping on drive mechanism, until one of them gives up and then once 2-3 teeth are out it will skip on any occasion it can when higher torque is required. There is 2 of the same gears to it. part nr. 4004254501 - GEAR 18/30T.
One on the drive train side and one on the waste auger drive end. They both are locking in 90 degree angle. The first job was a nightmare... then I actually enjoyed it as it was fun..

Re: How to identify my Bizhub C203 problem?
Before jumping the gun with noise coming from the waste toner system I would pull out the transfer belt (2 screws) and check the cleaning unit on there. Since you said you recently replaced the fuser maybe a piece of the orange rubber is preventing the trans belt cleaning unit from turning. This is assuming you replaced the fuser because the orange rubber roller broke apart?
By the way I have seen this happen many times. Almost every Biz 203/253 the orange rollers are breaking apart. I still have around 20-30 of these in service.
Shame but this series has reached "end of life" status with Konica Minolta. No longer supported and when parts are gone they are gone.Last edited by copyman; 05-31-2017, 11:34 PM.Comment

Re: How to identify my Bizhub C203 problem?
that is gears stripping to me.
check all the drive components and the fuser gears. especially the little ones on the main body.
will it stop if you open the trays?
i mean, that just sounds like gears not engaging to me. just try to pinpoint the sound to a specific area.We know a thing or two because we've seen a thing or two.
The medication helps though...Comment

Re: How to identify my Bizhub C203 problem?
Well, the sound does not stop, when I put out any tray. I belive (but I am not sure), that the sound comes near from the gears of the fusing unit.
I hope it is the fuser, but I need your help. Remember, the sound appeared first, while printing, and pringing still worked well, even if the sound is there.
I put out the fuser right now, and tried to check the gears. As I have no experiance with them, here is a picture that you can see for yourselve:
fusergears1.JPG
The gear wheels work well. Only the huge black one cannot be moved, because of that half gear inside. If I move it by hand, and use enough force so that it "moves over" the teeths of that half gear wheel inside, the sound is similar to what I hear when the machine is on and the fuser is installed.
But I do not understand the mechanism. What is the huge black gear from the fusing units right side for? And especially what does that "half gear wheel" inside?
fusergears2.JPG
And finally here is a picture from the gears for the fusing unit from inside the copier. I cannot tell if they look like they should? Regarding the two brown ones, the one in the front can be moved by hand, the other one in the back not at all. Both have a kind of lubricating grease on them.

Is there perhaps a possibility to turn the copier on completely to see if the sound is gone without the fusing unit installed? So I could see if my theory is right an if it really is the fusing unit, or the waste toner system or something else. Or is it impossible to trick out the sensors?Comment

Re: How to identify my Bizhub C203 problem?
the half moon gear is to engage the pressure between the 2 rollers, it does not turn all the way.
one other thing, with the fuser back in, while it makes the noise push the side door in tighter to see if it stops the noise.We know a thing or two because we've seen a thing or two.
The medication helps though...Comment

Re: How to identify my Bizhub C203 problem?
I have a suggestion.
If all the other choices just seem too hard, just pick something randomly that you know how to do, and say that is the problem. Go ahead and ignore the advice of the other people that suggested HARD things. I know many technicians that use this methodology. You never actually fix the problem, but then you never have to admit that you don't understand the advice. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: How to identify my Bizhub C203 problem?
Can't say I blame you for trying everything possible before having to deal with the waste toner pipe clog. Have you tried running machine with rear cage "hanging" away from machine. You can unhook the cage and that should give you enough room to look with flashlight to see if you see any gears jumping. Or at least pinpoint the area where noise is coming from. If I'm not mistaken the noise for waste toner clog is on right side (standing in back of machine) and all the drive stuff is toward the left.
Fortunately I have never had do that repair. Heard about it a being the worst type of repair on that series. I thought the Transfer belt sensor & laser unit were tough repairs, but heard this was much worse!
I had around 100 in the field at one time and never had one machine with the clogged waste pipe. Probably just jinxed myself but I only have around 20 left. If it does happen I won't attempt the repair. Now that they are "end of life" status I will just upgrade the machine.
best of luckComment
