Question about HP DeskJet 3740 InkJet Printer

1 Answer

Power light flashing really fast

I have a HP deskjet 3740. I got a paperjam a few weeks ago so I pulled it out. Right when I did that the light started blinking erradically. I tried to print to it again and it won't print. It won't let me turn it off with the power button, I have to unplug it. When I plug it back in it is still blinking reeeeeally fast. It wouldn't be so bad cause I only paid like $30 for the printer but It has a practically new ink cartridge in it so I was tryin to figure out the problem. What in the world is up with this thing?

My hp 3740 Printer's power button is blinking and doesn"t print since yesterday.

Blinking power light can mean a jam, out of paper, open cover, or bad usb cable.
Open the covers and look for torn paper and nothng blocking the paper sensor. Check and make sure your USB cable from PC to printer is connected.

unplug the cable from the computer to the printer, make sure you got all of the jam out. Unplug the power from the wall wait a few seconds and plug back in. (with usb cable still unplugged)Then try deleting all documents from the que. If the machine is in the ready mode, (green light on) plug usb cable in and try again. Let me know if this solves you problem. If not we can try a few other things.
