3245c black developer disappearing

[tinfox]

I've had to replace the dev unit twice in about 50k.

replace the black dev clutch, it's a bit of a job

Ditto on it being the clutch, might as well replace all 4 since you're back there.

Replace its black development clutch. And also replace its black developing unit. It will work fine. I faced this problem twice and i replace these two..


hope will work fine with u also

On a scale from 1 to 100, how much of a pain is it to replace the dev clutch? Cuz I may just swap the machine out.

Thanks

It isn't difficult, it's just time consuming. i had the same problem as you a while back, I just swapped the black clutch with the yellow as the customer does hardly any colour. You need a good hour and a half to do this job.

I'm curious. Why or how does a bad clutch cause this? Where is the developer going?

How long is a piece of string and where does that missing sock go in the washing machine?????

[tinfox]

The length of a string is philosophically debatable from many varied fields of the sciences from Newtonian physics to M theory.

As far as the sock goes, how do you know the sock ever MADE it to the washing machine?

BTW I have practiced "clutch replacing" in the office now to the point where I can do it in a half an hour.

I need to know why I am doing it. I don't get what is happening. The copies look fine for a few thousand copies/prints and then they start getting faded, when I look at the dev its thin all over. The copies/prints are never gritty.

I'm probably going to the account tomorrow with a clutch, a new DRUM and a new DEV. It better fix it. OR ELSE! ;-)

If after you replace development clutch, but still not working, I think you can also replace "development drive motor - k", just in case. it's between fuser and i/o board, that's a really big job.

The clutches stick such that the dev unit is being driven when it isn't supposed to be. This results in the dev being pulled onto the drum while the machine is doing it's 'housekeeping' a little at a time, slowly bleeding the dev unit dry of dev.

Ahh, okay. That makes sense. I was thinking slipping(not engaging) not stuck. Okay.

Will I be able to tell that when I pull it? Will it be stuck. I would just like to know that it was bad "fer sure".

thanks again!

Based on the ones I have changed you should be able to tell, they are sometimes stuck, other times just sticky (referring to the friction surfaces). I'd generally go and install a set of four, it isn't just black this can happen to.
