Question about HP LaserJet 2840 Printer
First check the toner ink level... if its empty replace the toner... if you have already done that remove the toner and then shake it little bit then put it back...
>> you can also unplug the power chord without turning off the printer and then wait for 30 sec and plug in the power chord.. hope this works..
