Ummmm, this is a site for technicians to get information from other technicians NOT a site for users to get free help. It seems that is what you are trying to do. Pardon me if I'm wrong.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

You have learnt the hard way why 99% of companies have a maintenance agreement on their copiers!
We're highly trained for a reason.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

We have had machines without maintenance contracts for over 20 years without problems. What is the difference they make? Also if this was the case the company who does the service cannot even figure it out.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

This is the main reason not to use the trial and error method of copier troubleshooting. You can spend a lot of money before accidentally finding the answer.

Just to clarify your commentary, you still have an issue with yellow, presumably dumping the entire yellow toner cartridge into the waste bottle? So after you vacuumed out the developer, there was only toner in the developing unit. If I were in your situation, I would hire a qualified tech. If you cannot do that, you could spend a lot more money, starting with a service manual, toner vacuum, and a yellow developing unit. Follow that with a color calibration.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

Thanks people for helping. Really appreciate it massively. We've changed the developer units and drums. New transfer belt also. The yellow is off the print area. Like 2mm from image area. Similar to a misregister on a printing press yellow not lining up.
We've had the service people out 4 times but they aren't winning also.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

It's hard to resolve some issues over an internet medium without you knowing the tech procedures and reasons behind some of the suggestions. Further complicating the issue is not knowing completely what has been done by untrained personnel.

To begin with, remove all drum and developer units along with the ITB. Make sure your machine is clean and pay close attention to the belt sensors. Replace any suspect units. Even if you have replaced them before. Replacing a unit without resolving the underlying problem can lead to the destruction (failure) of the new unit.

Once our machine and sensors are clean and we know the units are good, run each adjustment for print engine registration (calibrations) in the proper order.

At some point you may have to call it a day and replace the machine. The machine is definitely fixable, it just may be cheaper to replace it at this point.

The difference is that the technology has changed substantially over the last 20 years and continues to evolve.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

This thread is interesting. So you spent 600 on service engineers and they could not fix it. Wow, this is telling me that the UK techs are not properly trained on this product or they do not want to work on the machine or you are not giving the full details.
What did the engineers say was wrong or what did they suggest ?. From just a line issue on the machine that the techs cannot fix is quite extreme, unless some pwb is messed up. The machine has service modes that does registration adjustment and graduation to correct those sort of problems. Also the machine toner spills if bad will need to be cleaned up.
I would call konica UK and let them recommend a certified konica dealer who are trained on this machine, they should be able to get this going for you.

There is a coffee truck in my work area that has a sign in the rear and goes like this. " IF YOU DON'T EAT, BOTH OF US STARVE ".
Meaning you run a business, and you know your business and get an income from that business. But if you and everyone else also do the carpets, electrical, paint and every other things that there are professionls for, then nobody gets work and all starve. When you get this sorted out, do your home work and get a dealer who is certified on the product and get a service contract.

here is a link to the service manual. download or view at your own risk.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

Yes If you can list exactly what the 4 different engineers have done so far? what parts have they replaced? Did they update the firmware, if so what version is the machine on now?
Can I also ask if you are using genuine Konica Minolta toner?

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

Have you had the machine from new or was it a used machine also what are the counters
are the techs you have had look at the machine trained on Konica and specifically your model
it is very likely you have turned a simple fault into a major one by attempting to fix the machine yourself
and have wasted a lot of money at the same time
google can be a dangerous thing information in the wrong hands can cause more damage than good

i would advise calling a konica dealer in your area and be honest with them tell them exactly what you have done
and hope they can fix your mistakes

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

You mentioned having a machine or machines for 20 years without a contract and want to know why you should get one now. This is an example of an issue currently going on in my shop.

Customer buys 2 brand new Bizhub 554e machines. Build both, one has error code c-f902. A quick look up of that code says MFBS board or maybe firmware. Machine will not take firmware. We delivered the good one and have been working on the bad one for 10 days with factory input every day. Have changed everything related to it. Still dead.

This is how complicated new stuff can be. If you had bought this machine and took delivery of it and it coded a few months from now, you would be on your own. That is why you pay for service contracts.


Let me be clear, with a contract the machine would be serviced by qualified personnel but that does not always mean a quick fix. But with a contract, the money spent is ours and a loaner machine would be provided.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

I'm just going to make a wild assumption and figure that SOMEONE has run stabilization, gradation, replaced (not just cleaned) the Y Dev unit, and run toner hopper filling and manual toner add for the yellow.
another question: is this issue on copies only or all pages? If copies, has anyone cleaned the glass?

replacing the Intermediate Transfer Kit first thing definitely sounds like killing a fly with a shotgun.
i'll go with everybody else and highly recommend getting a service contract.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

Thanks Guys for the replies.

Now changed PWB Board. Still yellow is not registering.
Most components now changed. Please can anyone suggest something else. What everyone seems to not understand is yes it would be better with a service contract but even these guys can't fix it.

The engineer now says try the printhead itself.
What I wish to ask when the engineer took the printhead out it was lose on one end but the screw was tight. Is this like this normally or does it need to be tightly secure.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

Hey just to toss my .02c into the mix, konica offers a 3 year bumper to bumper warranty.
If an AUTHORIZED konica dealer cannot fix it he has to contact the DSM for that area. If he comes and cannot fix it within 2 or 3 tries konica will replace the whole machine.
Id like to think they do the same across the great pond as they do here in the US.
Look at the mfg date on the serial label behind the machine. If its less than 3 years you are covered.
Good luck.
