Question about HP DeskJet 3940 InkJet Photo Printer
My HP Deskjet 3940 printer light go on blinking, but it is not showing any error message. I am using refilled ink catridge for the last one year. is this the problem? please help. thanks
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.
