Hp deskjet 1220c power and resume buttons blinking

SOURCE: hp deskjet 6980 blinking lights

ok so for this situation you have to do a cold reset, and by this you have to go ahead while the printer is still power on, disconnect the power cord in back of the printer, and wait for about two minutes. power on the printer if printer still has the blinking lights then go to step 2.

step 2-after this check the printer if light are still blinking, then your going to remove all printheads, remove paper, and then unplug printer power cord from printer and also from the wall outlet, wait for 20 seconds, then power on the printer, wait for light to flash then install the printheads, put paper, and press the resume button.
*** always connect your printer to a wall outlet never to a power strip, the power strip robs some of the power from the printer***

change scanner cable.

The HP Photosmart Software must also be installed and running on the computer before scanning.

Check that the USB cable is firmly plugged in to the printer and computer. Unplug the power cord both from the wall socket, and the printer. Wait 60 seconds. Re-attach the power cord securely. Power on. Try the scan again.

Under normal circumstances, a blinking power button just means that the machine is busy with a task. Be sure to let it finish its current task before initiating another.
