Faded black print on top part of paper ,Task Apha 250 CI

[Guest]

Hi Guys,

I would like to seek help co'z our 250 ci that recently repaired and installed Maintenance KIT (fuser ,Transfer bed,Black Developer,Drum and rollers) im expecting that it will going to fine ,but when the technician try to print I notice that half of the top parts of the paper was faded specially on black & gray, I forgot to mention that the technician uses the old chip of the developer bec. the machine did not recognized the new developer. He said that there are more problem that co'z fading but I have a doubt... I already run refresh developer & drum color configuration gray adjustment and its still the same.

Please give me an idea weather the parts they install were defective or not install correctly.

Thanks you in advance

Emman

Are you sure the problem started after PM? Why didn't the technician just warranty the bad unit, warrany for Kyrocera is reallly good. The chip had nothing to do with your issue, it's probably something not seated right or bad unit, that's if the problem started after the PM like you stated.


Kyrocera doesn't play around, if you have an out of box problem, document it properly and send it right back.

The distributor only give a warranty for a month or 2000 pages of print which come first, we only rely on them because they are the only distributor in dubai, we had problem in black printing before and they suggested that it is much cheaper to buy maintenance rather than parts parts,

the quality improved after the tech installed maintenance kit but new problem show up that its print was uneven(half paper faded top part but on the bottom it was ok) .they insisting that there are other parts that are responsible for this new issue ,that was my purpose of posting to have an Idea about that new problem, next time they tell the reason I have some to say and argue about.

Thanks.

Did he also update the firmware (most recent is V12)? The last 2 updates are very important. A lot of copy quality issues are being solved and together with the new black development units they run very well.

I'm having a hard time seeing the specific quality problem with the black on this sample. Can you attach a U089 Gray > Black internal test patten?

There is one thing that has not been brought up yet. Quite often these maintenance kits (and developing units) get stored on end, so all the developer migrates to one end of the developing unit. To see this, all you have to do is hand turn the developing unit, and watch the brush on the mag roller to see that it fills in properly.

It's a pain to have to remove the developing units again, to shake some developer down to the other end, so on a few occasions I have run developer refresh to try to level out the developer in the unit. After 6 consecutive developer refreshes, the developer still will not level itself without removing the unit, and shaking it down.

It's also good practice to hand turn every developing unit before inserting it in the machine. A single seized new developing unit will break a $1 gear in the main drive pack, and add 3+ hours to your maintenance. It's worth the extra minutes to make sure the developing units can turn.

How do I hand turn the developing unit? Make one of these. It's just a scavenged coupler gear from an old developing unit on a shaft with a handle. This particular tool is made for the Sharp Pastel transfer belt unit, but you get the general idea:

Please update the firmware ver.12 and clean all laser(Black,Yellow,Cyan and Magenta).after calibrate the machine(color calibration, Reg Adjustment,Grey Adjustment,Drum Refresh in System Menu).i am sure your problem will be solved.Thanks-Rashid Iqbal

dear eizulueta
forgive me but i believe you are an end user ...
no problem in the chip most probably that maintenance kit for taskalfa 500ci and by the way no problem at all if he changed with old one ..
i check the attached file but i cant see any faded black but i will start with this:
1- did the technician clean the optic section ?
2- did he run maintenance mode 464 he should run this after replacing the maintenance kit ?
3- did he do gray adjustment ?
in fact there's a lot of suggestions to tell but i cant explain to you now
thank you

Only thing I'd add is to find out if the tech put in a GENUINE dev. unit, or REMAN. Something sounds fishy to me since he had to replace the chip from old to new DV unit.
Did it come out of a box that said KYOCERA MITA on it? Not sure if the copystar equivalent will install with no keying or functional problems or if there is one.
