Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

I don't know why people enjoying putting others down.
There is nothing cheap here or something that we doing for cheap!!!
Anyway we have had the PWB Board changed also but no luck!
The thing what seems to throw me of is that you guys all claim to be tech's but even none of you know what this could be even though we have told you what has been changed. So if I want to say anything is that this site and forum isn't helping and don't think much about your tech support. Only a few have been helpful but most are just here to dig people. Makes them feel a bit better I think and showing themselves as being a lot more intelligent than these people with problems. Sad really
The ones who have helped thanks a lot. If there is any idea of what should be the last thing to change. Printhead?

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.

I work for a 5star Konica Minolta dealer and we only get a 9 month warranty here in the UK..

Can you scan and upload an image of the issues you are getting? We might be able to point you in the right direction then.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

First not knowing your skill set I am recommending the following be done by trained/certified technician.

Remove the drum and developer units from the machine.
Clean the area inside and the laser slit glass
check the connections on the rear wall for cracks and deformities.
Check the removed units for leaking seals, broken gears.....etc
If either has issues then replace as a set (costly but might be worth it, check date code of new unit and make sure it is less than 3 months old.)
Remove the transfer belt unit and check all connections and the primary transfer roller inside unit.
If all this is good and it still does it then I would replace the following in this order
Hv power supply (run bias and ground to dev and drum units)
engine control pwb
low voltage power supply.
Then all harness between the contacts and the pwb's.

one or more of the above is the issue, it is a matter of finding which one.

If an AUTHORIZED konica dealer cannot fix it he has to contact the DSM for that area.

I have heard (I do not want to believe it but..) that this is for contract machines. Does not matter if a dealer or KM direct contract but must be under one. If it is a time and materials then it is at discretion of the DSM as to when and if they will visit. If the machine is NOT under contract then they will make suggestions on what to replace but will not replace the machine.

Comments like this will not make others on here want to help you.
We are not on site we can only go by what you describe. Some one may have seen this before and know what it is that caused it. I have seen this on another line and had several different fixes each time. The steps I outlined above is what I did to fix it. One was fixed by replacing the developer unit others by the HVPS one was the harness from the hvps to the developer contacts. Multiple visits can not be ruled out depending on how quickly it returns.

Good luck and hope this helps.

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

so the fault you are left with is no yellow image

it could be a few things

the printhead(laser) is not writing the image onto the drum

the developer not transfering toner onto the image on the drum

or the image not getting transferred from the drum to the transfer belt

run a copy and open a door to stop the paper half way thru the machine
look at the transfer belt is the yellow image on it if no
look at the yellow drum is the image on it if no
look at the yellow dev unit the mag roller should be covered in developer (the stuff you cleaned off on the previous unit)
this should be yellow if the toner is not getting thru to the developer it will be black in colour
no toner in the developer would cause missing image on that colour
you would expect to get an error code if this is the case but worth checking the developer unit
if yellow developer has toner the it is most likely to be the printhead

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

The issue is yellow is away from the image. Meaning its imaging but it rests away from the image. About 5mm away

[Elmo]

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

so your colour registration is out
when you replaced the transfer belt did you clean the id sensors
if after performing auto calibration it is not fixed then you need to check
for anything slowing the yellow image process
are the drum and developer units turning freely and fitted corrrectly
if they are ok then then next step would be to look at the yellow printhead (laser)

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

from the manual

[SmellsHot]

Re: PLEASE HELP WITH KONICA C284E! Expert advice needed

Did you remember to remove all the packing materials? Sounds like something in the drum is binding up.....Has the technician printed out a color registration sample? If you can upload that image to this site, You'll prolly get an answer to your problem. If your just having a yellow registration issue, and not with the other colors than one would assume that your problem is within the drum unit or laser. A simple color registration adjustment should be able to fix this problem.....

[WARNING: language contained in this post may be inappropriate for mixed company!]

To infer that some here are being condescending, disrespectful, unprofessional, or worse incompetent and besmirch our technical ability or knowledge is a fantastic way to receive far less assistance than requested.
I will help to the best of my ability, and if I can't fix something I will defer to the knowledge of a more experienced technician (who has no presence on this site) or the company's service support personnel (SSD).
If I do not understand something I will admit so, and I have no shame in admitting that.

Shame is a waste of time.

But to call into question the collective decades of experience by those on this site who voluntarily provided technical advice is in poor taste, in my opinion.

We, in general, are only here to help solve problems.



In the immortal words of Lil' Jon: "Don't start no shit, it won't be no shit."


Having said that, I truly hope that someone here has provided you with the technical help you sought and helped solve your yellow registration issue.

Have a day. (That's no pressure to have a good day, in case the day you're having just happens to be terrible.)

Just dropping in & may have missed something, but highly suspect the laser print head got bumped or affected in some way during the aforementioned job gone awry. Too many wrong turns. I'm lost, but I saw no mention of inspecting/adjusting/remounting the laser & connection?

I imagine that in over a year this issue has been rectified by now
