printer worked before but hadnt been used for a month, now a little led light just to the right of the power light is flashing and the printer will not print, the power button itself is lit and steady, is that little led next to the power button actually the power button led? when i tell it to print  i see a graph on my computer screeen saying its sending the job to the printer 0-100% then nothing,  i see in the printer readout that the right and left  ink carts are not in right, they were bought from dell and are the proper ones, i have put them in and out several times with same msg. i uninstalled the printer and reinstalled the printer with the cd that came with printer and that does no good, im wondering if i should change the usb printer cable, maybe the computer isnt talking to the printer, altho i get no messages from the computer saying so. i hate to buy new ink cartridges again.
