Question about HP DeskJet 3940 InkJet Photo Printer

1 Answer

Printer cartridge container doesn't stop in the middle

My printer is hp deskjet 3940.
When the ink that came with the printer ran out, I injected a generic into the cartridge. It printed well on its early printing but later the quality of print deteriorated until such time that it stopped printing. The printer's power indicator just kept on blinking.
I tried to clean it by wiping the cartridge's printing head and the roller.
After that the cartridge carrier never stop in the  middle when the  printer cover is lifted when it is supposed to stop.
The power indicator just kept on flashing.

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.

After my printer hp desktop 3940 prints it changes the status from ready to no toner and will not print again



I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink cartridge?
Please consider the following:
If you are using a refilled or third party cartridge that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks causing problems with print quality or damaging the physical printhead.
If you are using factory new cartridges, then please call the manufacturers Technical Support for assistance with the warranty on the cartridges

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 ).

thanks

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.

HP 3940 Printer not connected


The "remanufactured" cartridges can cause the printer to stop working by making a electric failure in the printer circuits. Those cartridges should be avoided now that HP makes extremely cheap and fragile circuits, not like the cartridge burner's HP's 600, 700, 800.
