As for the Power light flashing, maybe due to the fact your trying to print while the printer is offline it might flash to notify you or check this link...

Ink indicator keeps on blinking even with new ink cartridge.


The blinking ink light means that the printer does not recognize one of the ink cartridges. Power the printer off, pull out the power cord, wait for awhile, replug and turn the printer on. If the light no longer blinks, ok. If not, try installing another cartridge pair if you have them available - even if they are old used ones. If the ink light continues to blink with different cartridges or if you don't have any different cartridges, old or new, you have a dilemma. Do you want a new printer or do you want to continue to chase this problem. To chase this problem, get new cartridges and install them (half the price of a new printer). If that works your set, but if not you need to have your printer serviced which is doubtful that it is worthwhile doing so.

Put in new ink cartridge -- won't print


Try lifting up the cover. If the ink level is low in a print cartridge, the Print Cartridge Status light stops flashing. If the problem is not related
to low ink, the light continues to flash after the cover is opened. It might be that the new cartridge is defective. Check the connections and see if there isn't anything keeping it from making contact.

Hp deskjet 3940 printer light just blinks.It will not do anything else.


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 ).

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.

Printer cartridge container doesn't stop in the middle


It appears that the injection may have been lethal, it was still using the ink that it carries in its tubes then it mixed with the injection and is now blocked \ faulty. To repair it you could try getting a new set of HP inks.
