Junk Them. I have 2 on different machines and they both do the same thing. Green light flashing and they wont turn of nor will they print unless you unplug them for a while they will work again, but not for long. All I can say is they were cheap and HP made some junk, By another brand with a cheaper price on ink cartridges.

Hi,

in this printer only one LED present that blinks and two kinds of blinking one slow and other fast blinking

So if slow blinking inyour printer then this may be cartridge error, if you are are using refilled ink cartridge so please change change that one.

and if fast blinking in your printer then you cannot do anything.

in last go to AN Authorised service centre(to know the address of AN Authorised service centre in your city please visit at http://www.hp.com ).

thanks

SOURCE: My HP printer's light blinks, but it doesn't print.

two things to consider.
1. If the blinking is fast (like more than two blinks per second) then the printer is damaged. Either the main controller board is fried or the carriage/ink controller is damaged.
2. if the blinking is slow ( 1 blink per second) this means that either of your cartridges is busted. remove the black cartridge then close the top cover. If the blinking stops, then the black ink is the culprit. If not, replace the black then remove the other cartridge. THis means that one of your cartridge needs to be replaced.
