Not sure if you can do this, but I have used my 940c HP Inkjet successfully since it was new several years ago. I have found that anytime I have had any problems at all, I just unistall it and reinstall using the CD's that came with it. It has always solved any problems, in general. Specific problems can be taken care of by reading the Toolbox that is installed with the CD also. Good luck.

I have an hp deskjet 940c. I don't know if this is the same model as deskjet inkjet. Anyway what light is on or off on the front when a new ink cartridge(s) is needed?


For the HP 940c, there is only one light to indicate a possible low ink cartridge. The LED above the cartridge symbol (the only one without a button) will flash. (Note: this LED is the second from the left.) When you see the error code, open the printer's top cover. If the error is a low ink issue, the LED will stop blinking.

With the cover open, the cartridge carrier will move until the yellow arrow lines up with an icon on the printer itself. These five icons are in order from left to right (as you look at the cartridges) : tri-color ink cartridge problem, black ink cartridge problem, tri-color ink low, black ink low and cartridges OK. If both cartridges are low, replace the one indicated by the arrow. Then the cartridge carrier will move to indicate the other cartridge is low. (If only one has a problem, after you replace it, the carrier will move to the cartridge OK symbol.)

If HP offers the full-feature software for your OS, then install the software. Use the HP Deskjet Toolbox to get exactly which cartridge needs to be replaced without needing to be ready to replace both (or to monitor your ink level (approximate ink level)).

The manual for the Deskjet 940c is available as a PDF from HP: http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&lang=en&cc=us&docIndexId=64179&taskId=125&prodTypeId=18972&prodSeriesId=35985 .

I hope this helps.

The machine dos not measure the amount of ink in the tank it only counts the amount of squirts you have used normally its only a problem with refiled inks

Why can't I see the ink levels on my computer anymore. we just installed windows 7-64 bit. I don't know if black ink or color ink is out on my hpdeskjet 940c. It used to tell me.


You may have to update your printer drivers, try the HP website, follow links for downloads and support. Enter your printer model and operating system as you go. See if there's a driver update for you.

the moving ink frame is probably pointing to a symbol such as replace color ink( three dots on ink cartridge picture). Replace color ink. You are probably printing your black and white documents with colored ink--always select black or greyscale.

How do you check the ink levels of the cartridges on a hp deskjet 940c


Hi,
If the ink level is low in a print cartridge, the Print Cartridge Status light stops flashing when the printer’s top cover is opened. When you open the panel the ink cartridges slide to the center , as far as checking the ink level find and right click on the printer icon, click properties, and find ink cartridges and ink levels.
Thanks
Shereena.

My HP 940C only prints in shades of red. I replaced with new HP 15 & 78 Cartridges, still have same problem!


Some HP ink refills have the exact same product number but the electrical contact tips on the back of the cartridge are not the same configuration, resulting in red ink only being printed. One example is the DeskJet color ink cartridge C1823D having multiple configurations.Find a printer just like yours that's working properly and compare the contact tips if possible. HP tech help is a joke on this one. Good luck!
