I have a HP deskjet 930c that won't work and the left hand orange light is flashing. What do I need to do to fix the problem?

It is either out of ink or out of paper or the paper is jammed. Deskjet printers are some of the easiest printers to troubleshoot and maintain. I had a HP Deskjet Color printer for years and at least 10,000 printing pages before it dropped dead completely. I like the Deskjets as I can refill the ink cartridges at least 4+ times - even the color cartridges at least 4+ times.

What do I need to do to fix the problem?

I don't recall the colors, however the left most light is a cartridge status light. See pages 1, 25, and 40 of the DeskJet 930C User's Manual (http://h10032.www1.hp.com/ctg/Manual/bpd07427.pdf) for more info, and proceed as instructed or post back here.
