    Re: Toshiba Estudio 757

    You wasted your time of Dev unit, just fyi. They might lock up on you, but its never the dev units fault on this.
    Are the erase leds working? Whats the PM values at?

    I think you may be on to something, though thats nothing new. I worked on Sharps for 2 years but new company is Toshiba. How the page has a grey background on sharps would have almost garunteed a developer problem. Atleast personally I have never scene it where replacing the developer didn't solve this. Which of course bad toner could make it look like the developer is bad.
