2126 color registration off

[User Name]

Hey everyone, I have an FS-C2126 that's color registration is off. Specifically with the Magenta. The color reg adj in the adj/maintenance menu doesn't help any. I've attached a sample of the problem. Any thoughts? Thanks in advance!

Your yellow is off as well. If the registration adjustment doesn't work, I'd look at the transfer belt. Reseat the transfer belt, if that doesn't work replace it.

Check the sensor cover behind the black drum. It can get dislodged when trying to get the PITA black drum in. If it's good, there is a special firmware available on KDA for registration. If that doesn't work, the hotline will log in remotely & send it commands for factory default of registration. If that doesn't work, you're replacing boards or laser units.
I would send another tech to the call, then don't answer your phone for two weeks. We have a Main board coming because none of the other things fixed it.

Re: 2126 color registration off

We had the this many times lately and one in particular that would only stay for a week then be off again. Had tech services do the remote in thing that didn't work for us. The bulletin with the special firmware seems to have fixed most of ours and knock on wood our worst one has been good for awhile now.

Transfer belt has been in and out more than once. Will try this if the other fixes don't work.

The last time I called the Kyo hotline in regards to one of these machines, I inquired about that FW and the guy I spoke with seemed to think that the latest version already included it and he didn't know why it was still available. Sometimes I'm not so sure they have everything figured out though. I'll give it a shot.

I work for a small company with only two techs and I'm one of them and it's not even my call. I'm just helping out. Sometimes I wish I could send my annoying calls to my coworker but I'm the best at fixing things around here so it'd all come back to me anyway. (Just kidding Bill) XD

That's two suggestions for that now. I'm hopeful that will fix this one as well.


Thanks to everyone for the responses!

Re: 2126 color registration off

This machine is currently at out shop so I tried the special reg FW and it did not help. I guess I'll give the hotline a call next and see if I can get them to do their reg reset.

And here's how the reg adj chart prints out just to give a better look at how far it's off. Hopefully the reset from Kyo works. *fingers crossed*

Re: 2126 color registration off

hey U N , I know what its like to be the "go to guy" at our shop Im the Service Mgr ,trainer,carpenter,plumber,electrician,auto mechanic, oh and copier tech but only on the old ones the other techs dont want to deal with. The fix for reg problem is to print chart pick problem color in this case (mag ) needs to move aprox 5 mil up 5 mil lft, to do this enter adj mode pick (mv) enter (I)to move up (9)to move down then cycle power do this as many times as needed you can print chart to see it move, (if its this far off the chart lines will not help) then repeat for left(MH-L) or right(MR-L) to see your progress print status page after a few times check toner guage to see movement .only do one color one value at a time. EX (MV) I untill its good then do the left or right settings. it gets too hard to see changes if more then one is done at same time. calibrate when done to make sure it stays.

Re: 2126 color registration off

When you did firmware you get it code out like it says to ? I had one tech skip by something and code not come up then it didn't work at all either.

Hi Bill.

It appears that doing the extreme in the reg adj several dozen times did eventually bring the magenta back into alignment but why did it skew in the first place and will it do it again? We still have to figure out the issues with the yellow not always printing too.

Yep

That's probably a good idea for this one

Re: 2126 color registration off

I'm talking with our Kyo rep today about the Gemini line. We all know the update issues with this series, but there doesn't seem to be definitive answer on the registration issues. I was failing to wrap my head around the replacing of the transfer belt on these & the 5300 printers.
It seems that when the belts get some age, they get that chalky haze on them. This is affecting the registration sensors in the machine. They don't see the reg marks properly, which throws alignment off.
This makes sense to me now. It couldn't be cleaning on the hash marks on the 5300, because you only get it on the first page or two. I didn't understand why replacing the belt would make a difference.
So I'm thinking if you update the firmware & do the registration (special reg firmware not needed anymore), then if the problem comes back, replace the belt.
This explains why the registration problem started showing up after a few years.

Re: 2126 color registration off

I've tried new transfer belts on the problem machines and it never fixed the problem. It would come back in same short period maybe week or so. It sounds good in theory but I'm definitely not sold on transfer belts as a fix at least in ones here.

Re: 2126 color registration off

I agree on new transfer belt not helping. The engine board has just arrived for one of my FS-C5300DN. Will replace it in a day or 2, and will post how it worked out.

Re: 2126 color registration off

Just noticed this thread got revived. We were able to get the registration back on ours by doing the extremes on the manual registration adjustment about 20 times or so. I doubt it would have stayed though. We gave up on this one after the attempt to do that rather involved update didn't go so well (the machine started grinding afterwards). Kyocera is sending someone to give us a hand with that sometime soon.

Thanks again to everyone who posted with advice!

Re: 2126 color registration off

Hi all

We are having this very same problem now.

It started off with the colour registration being off, so we called and performed the colour alignment. That worked for a few days, then it went off again. We then installed the firmware to fix the colour shift.This worked for about 2 weeks and now the registration has again gone off.

We have lifted the machine to the workshop and are plowing through all available service bulletins.

Did anyone manage to find the overall solution?

Also, not sure if it is related, but this machine would also come up with the message "toner cartridge not installed properly." Although checking the gear on the toner cartridge seemed to fix this.

Thanks
