Question about HP DeskJet 3940 InkJet Photo Printer
i'm having a problem with my printer. light is continually blinking. i already purchased new ink cartridges but it still blinks. i ran the hp diagnostic but there seems to be no problem with it, no red x's. please help.
Hi, Try these links and look through them, hopefully 1 may of some use to you.
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...
Hope you get a good result.. cheers Ytee
