TaskAlfa 3252ci - Error Developer-Y

Re: TaskAlfa 3252ci - Error Developer-Y

I have exactly the same problem but with the bk dv unit. The machine have 320k pages out. My friend in Kyocera in my Country told me to check the connection between dv unit and another electrical unit (hv unit?) - maybe there is a bad connection and the developer is spilled off. He's told me that is a known problem in that model? Is it? What do You suggest in my situation?

If it was me... Id be checking toner drive, then k Dev unit. Do a Dev refresh. Does it suddenly fix itself then least you know the toner drive is working.

Always amazes me that these Dev units just keep working with no toner except 7000 error codes that don't flag to the user.

A little status-update for this thread.

We changed the "DRUM DLP CONNECT ASSY", Engine-Board and the Hopper. Same error occured after about 3000 pages.

Next thing to do is to change the DV-Drive-Unit.




Parts we changed already:

-Developer-Unit-Y (4 times)
-Drum-Unit-Y
-HV-Board
-EEPROM (new one from Kyocera)
-Engine-Board
-Toner-Hopper
-Drum DLP Connect Assy

Hi there,
I too have the same issue with the horizontal stripes (Barber polling) on black prints - Replaced the black dev and not working ok. But after reading some of the posts I fear the issue may reoccur.
Now having issues with the Magenta dev.
All new drums except for the Magenta drum (Original drum)
I suspect dev issue as a result of drums exceeding their replacement life.
Has anyone got any further thoughts or resolutions for this?

Wow I wanna know how 🤣. You would think the copies would be blank if it wasn't turning doesn't make sense. Did you see any fault with the drive when you took it out?

For better understanding how toner control on Iris series is working look for the attachment.
@40yearsplus:
Instead of magnetic detection, now we have frequency detection
@Ramatzko:
In your case, maybe we get problem with the controlling by Feed Image PWB and/ or Engine PWB.
DV connected to Drum_DLP_Connect PWB --> Feed Image PWB incoming on YC17/ outgoing by YC28 --> Engine PWB incoming on YC42
If we have bad connection, maybe system won`t recognize real value and engine won`t start toner motor for adding toner.
Look for U155 at first and check wirings between the pwbs.

By the way:
Did you unplug the power plug from the wall outlet before exchange from the DV units?
Did you run ALL needed adjustments after mounting?
Check U157, U158 and U984 for correct values.
If counters and/ or SN not real, system can`t calculate need amount of toner in the right way.

Deteriorated Toner apply operation performing timing: 1.In case continuous print continues more than 24 sheets, perform between the paper in the JOB....

I've seen that happen a lot and people complain the machine is slow. You can see the machine pause between each sheet for 1 second then continue. Starts fast then after a while will start pausing. Anyway to make the machine add toner faster to keep up? Copy quality is fine on the one I've seen do it and it always recovers.

I'm not really sure why you make a 50 page a minute machine the one I saw which will pause to add a tiny bit of toner and continue. Why wouldnt it stop for 5 seconds fully replenish or better yet just add toner on the go.

How do you use that u147? Would plus to that value just make it stop more? The toner add system is trash in my opinion if you do high coverage you always get problems.

Re: TaskAlfa 3252ci - Error Developer-Y

So you did put a Brand New Developing unit in the unit not just the developer. There is a name for that problem you have and it is called Barber Poleing, and I have seen a lot of my fellow techs have to replace the whole mechanical developer unit also to cure this, but just making sure thats what you replaced not just the Iron Filings (Developer).

Hang in there you will get it.

Remember to look for that Manual in the section here or ask for a Service Manual.

You can only buy the whole dev unit. Dev not sold seperately. Maybe he failed to run the dev adjust?
