Kyocera 2551 colors on copies and prints are not correctly aligned.

[Casian55]

Hi everyone, I have a Kyocera 2551 which is not aligning colors correctly. Black copies/prints are perfect but colored ones are not (see the attached image), I have tried both automatic and manual color regulation but first one is not working and second one does not keep the settings I apply. I've also tried to replace a color drum and developer but nothing has changed.
The MFP is running with 2NP_2000.004.104 2016.06.29 Firmware. Any suggestion?

I believe if you go to Sim 468 and go to execute then turn off copier and back on you can go to toner curve and adjust back to normal. It works on a FS- C8525 .

Jupiter series

Reset by U468
Wrong color registration after running the adjustment by the system menu:
Run U468 / “Initialize“ / “Execute“ and press [OK] key.
Check if all values of [Auto] and [Manual] = ”0”
If values = “0“ > U001 and press [OK] key / if other values > repeat U468
No other changings, no copies/ no printouts during this procedure!!
Finally run System menu > adjustment/maintenance > 2. page >
1. Calibration
2. Color Registration/ manual/detail.

Is there a lot of C76XX codes in the log?

Replace belt unit , then calibrate

@Jkiss
take a look for the sample and tell us how it can be possible that belt is the reason if the colors are shifted against the running direction.
He must have a lot of C76xx because of wrong position from the patches.
Patches would written from the laser on this wrong position because of wrong "zero point" for color registration. (if internal value > 255 , system can`t calculate correct position anymore)
He has to "kill" this wrong value by U468 at first.
Additional FW V3.02 or newer needed, otherwise it will happen again.
One part of this FW:
The fur brush in the primary transfer section is rotated at high speed when the auto LSU cleaning (each 1000 pages) is executed so that the amount of the
toner in the fur brush is reduced to prevent the toner from reaffixing to the transfer belt.

Did this resolve your issue? Just curious...we have similar problem.
Thanks.

Good information, KYO.

@avio2/ greetings to Roberto
I think it`s his translation from english to italian (In near future i will publish modified english version incl. Mebius and Sirius)
I can`t read italian, but hopefully he didn`t forget something during translation
(this happened during translation from workflow description for Jupiter/ U464....)
