ar-m450 developer issue

[DINGO]

Hy
Good night, y need yours help/opinion if possible for:
Today, like the others times, y change the developer in one ar-m450n,
and the issue was, y execute the 25-2, and gives me higts number
like 177 and the error EE-EU?

-the developer was new.
-the unit is ok, everey gears works good.
-the the develper sensor was clean??

some idea?

thanks in advance.

Do a search for EE-EU and you'll find some helpful tips and things to look for.

Try running TC 10 (toner add) and then run 25-1 to see if value lowers; it might have been new but have an old 'shelf life'.

When you reset the dev, did you reset the rotation counter as well in 24-11?

I'd reset both the dev & rotation counts and run 25-02 again.

Especially on those machines, I'd pull out the toner sensor & wipe it off after dumping the developer. You can do it carefully with the new developer in it.

EE-EU is an undertone condition. I suspect that your developing drive is not turning. I've seen damaged couplers, and broken mag rollers. Truly, the rear end of the mag roller with the shaft and coupler just twists right off. If you put a drive handle onto the developer drive coupler the coupler turns, but the mag roller doesn't. =^..^=

Ok
Thanks for any ideas.
Y do this:
- clean again the sensor toner
-execute 5 times the 10-1
- and again two times 25-2 CA

and at moment stay good, y don,t now how many time works good.

the 25-2 stay now in 125 and dthe copy was good.

thanks for all ideas, but my doubt was because the developer was new.

thanks a lot,

This may sound stupid but did you use the AR450ND developer? If you used the AR455ND developer you will get something like this? Did it myself once so that is why I am asking.

Good luck.

Hy
In case y´m using developer 450ND,
At propose, sometimes y use to the 455ND, but only 450grs, not the all 500grs, and never have problems, and with 202ND to( 450grs )works good.

thanks
