Hi All,
I got a problem with CN C5535i, which is the error code "E025-0251", I've checked the SM that is Magenta ATR sensor problem.
Here is what I've been done, replace a new developer unit, it works at beginning, but after about 6 or 7K prints that happen again.
I've check Drum unit and DV unit that is no broken or damage, also I've check service mode the "DEN-M" is -3.40% and "SGNL-M" is 253, all looks different than the other three.
Any suggestions or assistance will be grateful, thanks.
