Running printer.I have two toners(starter and running).I have upgraded the firmwire that it does not tell computer
your toner is running low or stop to print.But the firmwire works only on windows XP.
So you have to use it Windows XP.If the toner is empty,just refill it and print as you wish as many.
NO INTERNAL OR EXTERNAL PROBLEM.no box.
