iR ADV 9070 PRO Developer Unit

[V-P]

Hi Fellas,

In a 9070 PRO I replaced the black drum + developer.

The problem is that the new developer (FM4-6615-020) does not fill up the entire drum surface (so to speak).

Image is attached (PG-5 test).

I put back the old developer unit and the image is fine.

What can it be ?

hello.well if old unit works fine then it has to be the dev unit itself.maybe the unit was on its side for to long.starter moves to 1 side.maybe the spiral inside isn't turning.try open unit so you can see starter.see how its inside.maybe that will help

That is exactly correct. Occasionally I find I have to open the top of the developer to look and see if the developer is even and not packed to one side. I have gotten in the habit of shaking them a little to even them out. About 25% are not even. I think on those two screws to get the rail off and two screws on the ends and pry the lock tabs open.

Some update on the issue.

Since new developer had issues - I inserted temporarily the old one.

After some days customer calls and I see that the old one was being depleted.

So I thought "hopper unit".

I removed it and found that FL3-8703 was broken and I replaced it and also cleaned the sensors and the piezzo sensor.

Put back the hopper with the new developer and a new toner bottle.

Did a Ini-set - still the same
Did a second init-set - coverage was improving.
I had to make like 5 times INISET and the PG-5 was full.

Still it is not ok. I cannot figure out why...

I also tried to swap high voltage between cyan and black - but still the same

Maybe it doesn't matter but the copier was moved from one location to another - maybe bumps along the way !!!

Strange. Normally when hopper gear breaks it gives a E020 error.or at least a E020 err. But it's a machine..if it is hopper and you can't see a issue try a diff hopper.I have had issues where I replaced parts inside hopper and still gave issue at the end when I replace the hopper with a used 1 I found at the office that prob went away and just needed to fix problem with used hopper..after you replaced gears did u try new Dev unit again..maybe old unit starter has depleted and causing issue.

Hi dude!

Thanks for updates.
I have similar issue few years ago on the same model.(9060)
I solve the problem with simple shaking developer and execute Stir Bk. Maybe luck. Probably you already read this bulletin.It's not really the same issue but...

Re: iR ADV 9070 PRO Developer Unit

Hi Z,

Thnx for the advice

Stir-Bk did flatten out the gray on the page, but I still got emptiness on the rear side.

Than finally the machine popped out E020-04a2

Next move is new hopper and hopefully I am done.

Thnx,

Re: iR ADV 9070 PRO Developer Unit

Some more update:

I did replace the black hopper with another working one.
I did replace the black developing unit with a working one.

Result:
The PG-5 is Ok but if you output like 50 A3 of PG-5 , gray density starts to get lighter.
I did check the COPIER > DISPLAY > DENS-K often.
In the beginning it was round -1 and than it was progressing towards -7.

So I did:

1. DC CON Clear
2. Switched DEVELOPING H.V. PCB ASSEMBLY between Black and Yellow
3. Reseat J1234 and J1235 connectors on DC Controller PCB

Nothing - still the same.

Than:
1. Perform a DPC
2. INISET-K.
3. Auto Color Mismatch
4. Shading Correction with a densitometer
5. Full Auto Gradation

As a result of that Value of DENS-K came back to -1.
Did again some PG-5 and the value started to go for -7 again.

I am puzzled.

Maybe FM3-9573 Hopper Driver PCB ?

Ideas ?

Re: iR ADV 9070 PRO Developer Unit

Follow directions very carefully when replacing devs on these units...Make sure potential control is on and working properly. If its turned off and you install a new dev and initialize it, IT WILL EMPTY OUT THE DEV ASSEMBLY....

Re: iR ADV 9070 PRO Developer Unit

Some more updates :

To Canuck: Potential control is - On

I did replace DC Controller also. Still no good.

If I print 100 PG-5 ; the DENS-K value goes from -0.2 till - 5 or -6. I have not pushed it anymore.

I can turn it into normal values by Function / Install / TD-AD-K

Than the same story again.

During PG-5 printing - I can see on the back of the machine - the hopper motors running on and off every second.

During TD-AD-K - I can see the motors running for a couple of seconds.

I cannot figure out what is wrong...

More copies you need to work to fill it up of toner for your new developer unit that's why the entire paper no print out when you make it for test print.......

Do you find the solution to this problem, because I have exactly the same thing on my machine
thank you in advance

It looks like the developer unit to me.
