Greetings to all, I have a problem with this olivetti "indicator light flashes Toner" I tried to replace the developer and do not sim. 25-01, the toner is new and original, I also tried to change the sensor of the developer, but nothing the light turns off, what I can say is that the turning off and on the copier itself runs for 3-5 seconds then as if you turn off the flashing and remains, to specify that this machine model is equivalent to the SHARP AR 163 .... thank you so much who can give me a hand to solve this problem ... I do not know what to do
thanks
thanks
