Did you print any non-regular media that might have contaminated the printer?[\QUOTE]
yes actually I did try to print with the photo paper but it didn't end well, it didn't go inside the printer but it more than a month ago.
Are you operating it under extreme climate conditions?
No, I am here in Mumbai
I did notice some smell around it something like a over heated Iron press, But it was printing fine then, that event occurred just before the day all black thing started coming out
