Question about HP DeskJet 3940 InkJet Photo Printer

1 Answer

HP 3940 Printer not connected

I have a HP 3940, which I have had for about a year. I have had a couple of sets of cartridges during that time. In each case these were HP cartridges and I have had no problems with the printer to date.

When the last set ran out I purchsed remanufactured cartridges from a reputable retailer. When I installed these I was unable to print and had an error message "HP Deskjet not connected". I have uninstalled and re-installed the printer but this has not solved the problem.

When I reinstalled the printer with the old (HP) cartridges installed the printer printed OK. It also did so after shutting down and restarting my PC. However, when I last started my PC (with the old HP cartridges installed) the "not connected" error message reappeared. My operating system is ME. Any suggestions would be appreciated. Wayne.

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.

3940 blinks and cant pritn


hello lotsaprint, ipang
Few days ago i had the same problem with my hp 3920 color photo printer. All i did is removed the cartridges one by one and the problem was solved. Try removing the color cartridge first, then switch on the printer see i the problem is solved the cartridge contacts must be dirty. clean it with soft tissue (dont use any liquid) and reinsert the cartridge. If the problem persists u may need to replace the cartridge. Check with a new one if u can borrow one from anyone b4 u buy.
Repeat the same procedure with black cartridge if necessary. If u r new and need guidance for removing the cartridge, then do the following.
1). Switch on the printer.
2). Open the front cover. The cartridge will now move to the
center.
3). Switch off the printer and remove the power cord.
4). push the cartridge gently downwards to detach.

Close the cover when u r done with above mentioned.
For more info see the user guide u go with the printer.

Hope this was helpful

I have an hp Deskjet 3940 printer and it wont print everything in a page. Sometimes even coloured pages it will not.


dear mdoris5, First confirm that how often u use ur printer. If u need not take prints everyday then atleast you should switch on ur printer daily, because when the printer switches on it perform a cartridge cleaning task.
The cause of the problem might be :
1) Clogged print heads due to no use for long periods.
2) Empty cartridges.
Try refilling ur cartridge or use new one to check if u can borrow one.

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.
