Has anyone having problems with imaging units with these models?

One of the colours depleting toner and dumping it into waste toner box.

Also noted (on installation) too low or too high TCR ratios with coresponding service call and cca 300V difference from ither colours for Vg and Vdc.

Developer bumps on magnet roller and lack of developer on magnet roller.

It is too early for us to say but your problems are strange. It's developer who dumps in WTB usually, when overtoning machine has CQ problems like foggy background etc do you have CQ problems?
Too high TCR ratio definitely isn't good like high voltages. Check SM for proper voltages.
Thanks for the warning.

The only way (on these models) to transfer toner to WTB is from magnet roller to drum (and even transfer belt) without being transfer to paper.
Developing units of A3 color models have output to dispose surplus of developer to WTB. These models don't have that but only the output for toner scraped with drum cleaner.
Don't think it's a voltage problem because if there's no charge on magnet roller or primary charge roller that would be seen on paper like fully covered with particular color.
Difference in voltages can occur after image stabilization as machine try to compensate after reading weak (too light) patch from transfer belt in order to maintain image quality.

Could this be a FW problem?

P.S. Forgot to mention in my first post, when I tried to pull out problematic IU its drum was fully covered with toner.

Hi, I had the same problem with Bizhub C3300i.
The client changed the yellow toner on around 800 total pages and after around 100 pages the yellow is empty again. The waste toner box was almost full with a yellow toner. The drum on the yellow IU was covered with toner and the developer was depleted. I toped up the developer using one from Bizhub C220. The TCR ratio normalized at around 6,5% and that seems to fix the problem for now. I inspected the drum surface and it is clean. I don't know the initial reason developer was lost. What color is your problematic IU, REGSIS? I don't think the dumped toner passes through the transfer belt. I think the drum itself is faulty. Maybe the problem will reappear. Or maybe they just did't put enough developer initialy?

I had problems with 5 of these. IU Y and C mostly.
Noticed that was happening with inital FW G00-23, and not with newly released G00-38 machines.
Also noted that these strange behavior starts after toner change and can also stop after toner change, and after that reappear again on next toner change.

There is no official solution, only information that a change of particular IU solved the problem, but i strongly recommend a FW update to G00-3B.

I had no chance to test it or solve the issue by myself because KM replaced problematic printers with new ones under warranty.

At the moment I have no customer who replaced the toner but Konica Minolta before installation highly recommended me to use the FW G00-38 because the FW G00-23 is problematic


Now it is possible to upgrade to the G00-45 version. A big update will come soon.

Avoid V45 at all costs.

It it has a bug that can brick the machine and is unrecoverable.

I would wait until the next release of firmware.

Hi, can you give more details about the bug that can damage the mfp?

The firmware version on my faulty machine is G00-38. So that highly recommend version by KM is also not good. I also noticed the TCR values for IU C started going up and are now at 11%. I guess it will soon start to dump it's developer.

I think the problem dealt with BH secure..You need ver 45 to fully enable BH secure and if you partially enabled then went to ver 45 it couold cause a problem..We were told not to enable BH secure until ver 45 was released. I have not heard of any other issues caused by this release. E

It is my belief that Konica is having a large problem with the TCR sensors. I have similar problems on a 3350. It took 4 Y IU to get a good one. And you can imagine the run around in between. The TCR sensors are not reading and reporting reality.

Hi, can you give more details about the bug that can damage the mfp?
It sometimes causes an error code because it changes the storage option to CF instead of hdd.
This isn’t usually a problem because it can be changed back but it V45 doesn’t display the buttons necessary to change it and then you are stuck with an error code you can’t get rid of.

It doesn’t always do it though so it’s a bit of a lottery.

We have been advised not to update to this version.

This is in Europe though.

Dont know now if it’s the same in other regions.

Maybe I understood. I think I heard something from KM. When you initialize the machine, the HDD is deactivated. The problem is that in the iSeries there is no HDD and therefore an electronic card (perhaps the ssd?) that causes the error is deactivated.

I have 4 machines in field this problem.
3 C3300i and one C3350i.
Every machines have to high tcr state.
3 magenta tcr high and one black tcr.
I try to lower the tcr from 0 to -3 but not good.
A tcr is over 10% when I print halftone the tcr is reduce to normal 7-8% but after not to many printed pages go back to over 10%.
I will try the IU change maybe it works.
The most important I use the G00-53 FW.

Hi,

If I could hijack this thread please.

I'm having this exact same issue but on a C3350i so far I have replaced 2x yellow IU, 1x black & 1x cyan machine only has 12K total count.

The machine will call for a toner customer will fit new (genuine) however the message will not clear.

Fitting a new IU of that colour temporally resolves the issue.

I can not see any bulletins on this issue from KM?

Thanks for the info, i’m going back with this B5 firmware.

I did read on here that there is B6 Firmware out but we don’t have it in the UK yet.

If anyone could share a link to that would be awesome.

B6 firmware resolve only this

2.2. Fixed issues

It may take long time to start up the MFP in case the network cable is not inserted into the MFP.

B5 firmware does address the high toner consumption and iu destruction issue. If its loaded on a machine with already partly destroyed iu you will still need to replace it when it fails but after that point it should be fine. The duration of agitation of the toner /dev mixture has been modified to stop incorrect readings from memory.

There are of course other reasons for ius to fail, ie loss of drum charge and solid pages of the relevent colour but these are physical issues that you need to find and fix, not software.

Same problems with IU too Magenta and yellow, like you.
Nothing else to do than replace these faulty UI..

B6 not available here too.
Can anyone share this fw please ?

This is not mentioned at all in the program release information, have you found this in a bulletin?

I do not think it will be mentioned in a bulletin otherwise it would start the valaganza of requests for the guarantee

It's not mentioned, but the fix IS in this fw. :cool:

I was told that this could be caused by bad spring contact on the HV... Did not solve my problem, had to replace 2 IU's

Attached document is added in the box of new machines. Instructions to shake IU’s and check TCR values... And replace IU when too low.

So B5 contains a more permanent fix than G00-4E/G00-7D?

Inmy field I have 4 machines which give the following error (2555).
Allthis machines have blurred image with magenta, and of course themagenta TCR is below 6.5%.
Onemachines I change the TCR level history to +3 which is the maxsetting.
Thismachines run 2 days (not dropped the 2555 error code) after theyempty the new toner whick is 6K toner if I god to know.
SoI relese this machines and order the new IU unit which is not to comein this time.
Everymachines have G00-53 fw.
Thelast information is in this case need to update the fw G00-B5 whichis not the last fw.
Soif the IU will arrive to me I change the IU and flash the fw.

Is it about abnormal toner consumption? On some new installations they even require you to unmount UI and shake before booting the first time.
But I believe that with the new firmware it performs internal rotations to avoid the phenomenon.

Yes, they have added a 'toner agitation mode' basically with the paper try pulled out run image process stabilisation.

Well, I thought it was an IU problem but posting it here in case it might help others.

Got a call on a C4000i last week and customer said they just put in cyan toner and then the blues started looking purple. Then they got code C2551. I take an IU over forgetting to check the TCR ratio and replaced it thinking it had just failed since the bird test chart had hardly any cyan on it at all in addition to the color registration being off.

They called back and said it's saying to add cyan toner. I go over and the cyan toner is still full because it's heavy and weighed what felt exactly like the new one I took over. I flipped the toner over and found this:

https://i.imgur.com/kmsMzUi.jpg

The tape covering the hole didn't come off completely and totally blocked the toner port of the new bottle. So, I'm thinking I should be able to just tone it up and did that in service mode using manual toner add. Took about 3 minutes and I checked the TCR of cyan and it was 7.18%. All good! Or so I thought. Because the machine had come to a complete stop requiring a new cyan toner bottle and it has the stupid chip on the bottle, it would say to replace the cyan toner every time the machine was turned off and back on. If I opened and closed the front door, the message would go away because the percentage was correct.

I had to put in the new toner bottle to get it to reset and keep the message away.

I really wish KM would make it so that as long as the TCR percentage is correct, it wouldn't pay attention to the chip if it was new or not.

I would try Engine FW DipSW 6

Except that only does auxiliary toner replenishing not reset the count of the old (full) bottle. I was already able to tone up the machine with the old bottle but because the machine came to a stop requesting a new bottle and a new one wasn't installed (because the chip wasn't new), it kept saying to replace the C toner. It's just bad programming on KM's part. As long as the machine is able to maintain the proper TCR percentage, then the machine should ignore the fact a new bottle hasn't been installed and just keep going as long as the TCR can be properly maintained. It would be super easy to provide this with a F/W update, but getting them to do it is like pulling teeth.
