What is the meter on the machine? Has the drum been changed? Why do you think the code came up?

[masterteknicion]

If you don't want to replace the developer replace the atdc sensor or add some toner to the machine and run F8

[kiwitechnician]

I would change the developer, It's really not big deal, a few bucks.

and then run F8.

Why don't you want replace dev?

Normally the life of developer is near about 80000 copies.
*If the developer life is completed in your machine then you replace the developer and run F8 that will fix your problem.
*If the life is not completed.....
..Enter in service mode check ATDC gain its near about 154.
..Increase this value near about 180.
..After that exit from service mode and switch off/on the machine.
..take out the toner bottle from machine.
..open the platen cover take some black copy (20 to 30 copy).
.. After that enter in service mode dcrease the ATDC gain on privous
value.
That will help you

Good Luck

How do you increase the ATDC gain, I can find it, but can't change it.

Hi Kingarthur,
How do you increase the ATDC gain, I can find it, but can't change it.

Adgustment Procedure-
1-Call the Tech.Rep.Mode.
to the screen.
2-Touch the keys in this order (Tech.Rep.Choice.)- (Printer)-(ATDC Sensor Gain).
3-Press the clear key and change the setting value
using the 10key pad.
4-Touch END.
Adgustment Range is (0 -255)

Good Luck

these machines are different then the 3510 series. then the drum was due you could go into the counter mode and just zero them out. I tried to on a bizhub 350 and the thing gave me the atdc code. minolta just reccomends that you replace the developer and drum unit together. or it will not work. at least it did not work in my instance. so if you want to cause a big problem just replace the drum unit. I think that if you just clear out the numbers and do an f8 this machine will outsmart you. let us know how you do on this. ok?

Re: bizhub 250 b/w C2557

If you forgot to clear the counter before replacing of the developer then you have to open the ADU door, turn ON the machine, go to the Service mode, clear the consumables counter, run F8. Thats it. Hopefuly it's OK. Cheers
