Let me see if I understand, you put another Magenta IU in and the dots disappear and you want to know if anyone has a clue what it good be? Didn't you already answer that question when you swapped the Mag unit and dots disappeared? Bad magenta IU?

The parts yield that you are basing your assumptions on is based on 4% image fill of each color. If perchance, you were printing 7% fill of magenta you would reach parts yield sooner.

This begs the question what percentage image fill were you printing?

There are many other factors affecting developer life:
How many prints per run?
How much image fill?
How many years has the unit been in the machine?
Are you using genuine toner?

The short answer is: Just change the unit and stop thinking about it. Most of the factors that I've mentioned are things that you cannot affect. =^..^=

i will change it when new one arrives, just wanna know if exist any procide that i can do for this or what could do this because the IU had 36% left and maybe 2years on machine, toner is genuine , if print black its ok only colours do that sometimes with less dots

I have this problem few times on c25,c35,c3110 and in all cases problem was high humidity or very low room temperature.
That same bad IU works ok at summer :)

yh the room is kinda bad very old and this only work like 2 days for a week any advice for fix it now?

Yes, that is the same situation like i had.
And even if you put new IU you could expect very soon same problem.
I assume toner and developer in IU during long standby apsorb moisture and that effect you can see as color spots on paper.
I think only solution will be to move printer in better place with normal room temperature.


Operating environment
Temperature 10°C to 30°C (50°F to 86°F) (Fluctuations of no more than 10°C (18°F) within an hour.)
Humidity 15% to 85% (Fluctuations of no more than 10% within an hour.)
