Jam light always on
Jam light is always on, and i cant print
i have open every single port and tray and there is no sign of paper jam...
i have pressed the test switch, below the formatter card and printed one page with horizontal lines (engine test) ... that means that i have to change the formatter card?
any other way? because it's an old printer and the formatter card is too expensive.
this is where i find out about the test switch: http://www.laserpros.com/tech_tip_p2015....
