You can reset the hp 940 cartridge very easily by following these steps as under..
1.. just take and insert the cartridges in the cartridge holders gently and softly until you hear the clicking sound
2.. just reset your printer and then start the recycling process so that the printer refreshes the cartridges.
3. Press the OK button on the printer and hold it for 5 to 6 seconds, and at the same time when you are holding the OK button press the red stop button also while holding it till the LCD gets refreshed
thanks
This works for any HP printer. Keep up to 3 empty ink cartridges around. Most printers only remember the last 3 swap them out then place you filled in as the 4th and it tricks the memory.

if you are using a refilled catridge you would not get ink levels right.
if you want right ink level use genuine ink catridges.
you can try taking out the catridges turning off the printer and turning it back on and then reinstalling the catridges.it might not help so if possible buy hp ink catridges.

I had same problem, and i solved it.
I opened my hp 8250 and removed it`s battery. It is located on left side of the printer, on the main board. You need to remove plastic covers , and then remove 3 screws holding board. You can move board just enough to get damn battery out of there. Now it works perfect!
I can send you some piccs if you need help.

I tried blowing through the holes whenever printing quality is not good and it sure did the trick. I do printing a lot. about 40 reams a week and consume just about 300ml of ink..

There is no way to reset the ink levels on this cartridge type yet. Any replacement chips on the internet are violating patent law. Once the chip tells the printer it is empty it will not print no matter how much ink is left in it. There is always a lag time between the introduction of a new cartridge type and the ability to fill it properly. For refills I would recommend Cartridge World when this cartridge type can be refilled.

I used the drill method in the video. Took a while to get it printing again but so far, so good. THe low ink light went out so the pritner thinks the cartridge ink level went up as it did.
Will post again if it breaks.
