Question Author
ChuckFickens really grateful for your advice - bought new chip from EBay only £16 and worked a treat, could not have afforded £100++ for new conductor. Advised by supplier to empty waste toner with care !! I thought it would never stop coming out. Can you possibly tell me if this is something which should be done on a regular basis? I don't think it is in the instructions but wonder if it caused the problem.
Thanks again
