Printer Toolbox Not Recognizing New Black Ink

My apologies, I believe I posted this post on the wrong thread. Thank you.

Hello,

I recently replaced my black ink cartridge in my HP Deskjet 6940, however the printer's toolbox on the computer still only sees that there is low/no ink as far as the black ink goes. I have already tried reinstalling the printer's drivers and that didn't work. Any ideas or suggestions? I would really appreciated it, thank you.

The Deskjet 6940 will only show ink level for original HP cartrdgies. Refilled or reman cartridges will show as empty or unknown in the toolbox. This is not an issue with the driver, the cartrdige itself has information that it has been previously used and this is not resettable. You can continue to print with a cartrdige that has unknown ink levels, you will just not get low ink warnings.

Hello! We have a Brother MFC-J615 printer & we have been having a problem recently with the Black ink. It just randomly started to not print any black ink, but the other colors are just fine. The ink...


It sounds like you're not using the correct ink for the printer.

Each printer requires a different formula and thickness of ink for it to work correctly.

Have you recently started using a new bottle or topped up with a different ink in the system?.

I replaced my black cartridge and now my ink/paper light remains lit and when i press it, after a few noises, the green power light begins to blink. i have recently replaced the color cartridge as well.


It is important for you to post the make of your printer. Anyway, it sounds like your new cartridge is faulty, which is not unusual. First of all, turn your machine off, unplug it, wait a minute, then plug it in and turn it on. If the problem is still there, try another new cartridge. If the problem goes away, get a refund for the one you just replaced.

I am unable to print on my HP Officejet Pro 8500. i have recently replaced the 940 black cartridge and since then have been unable to print. i notice there are print cartridges in the main body as well...


you can check the ink level from following steps Method one: Check the ink levels from the idle screen on the color graphics display Look for four icons at the bottom of the color graphics display. The icons represent the ink level remaining in each of the four color ink cartridges: black, yellow, light cyan (blue), and light magenta (pink). A larger and more accurate view of the ink levels can be displayed from the Setup menu. If an ink cartridge containing non-HP ink is being used, a question mark displays instead of the ink drop in the icon for that cartridge. The HP All-in-One cannot detect the amount of ink remaining in ink cartridges that contain non-HP ink. Figure 1: Non-HP ink iconc00841629.jpg NOTE: HP cannot guarantee the quality or reliability of non-HP ink. Printer service or repairs required as a result of printer failure or damage attributable to the use of non-HP ink will not be covered under warranty. If a hollow ink drop icon displays, the ink cartridge represented by that color icon has very little ink remaining and will need to be changed soon. You might be able to continue printing for a short period of time with ink remaining in the print head assembly. Replace the ink cartridge when the Replace Soon warning message displays on the color graphics display. Figure 2: Low ink level iconc00841630.jpg When the Empty Ink message appears on the color graphics display, the indicated ink cartridge is out of ink. Replace the indicated ink cartridge. Method two: Check ink levels from the Windows computer The estimated amount of ink remaining in the ink cartridges can be checked from the computer. See the on-screen HP Director Help for information on checking the ink levels from the Printer
  1. Open the printer Toolbox. To do so, do one of the following:
    • Open HP Solution Center, click the Settings menu, then point to Print Settings , then click Printer Toolbox .
    • Right-click the HP Digital Imaging Monitor in the tray, then point to your printer model name, and click Display Printer Toolbox .
    The Toolbox opens.
  2. Click the Estimated Ink Level tab. The estimated ink level gauges display.
Method three: Check ink levels from the Setup menu
  1. Press Setup on the printer control panel.
  2. Scroll down and select Display Ink Gauge . The Ink Gauge status from the Tools menu will only display on the color graphics display.

If the ink level is low and the cartridge is new please contact the dealer from whom you got the cartridge and if it shows that the ink level is good enough please comment so that i can give you another step to perform

Ink lvels


Hello holliston,
You can try the following steps that should help you determine your ink levels.


  1. Open the Printer Toolbox . There are two ways to do this:
    • Click Start and select HP Solution Center . Select the Settings menu, then the Print Settings submenu, and finally the Printer Toolbox .
    • In your printing application, click File , click Print , and click Properties . Click the Services tab, then the Service This Device icon.
  2. The Printer Toolbox opens. Click the Estimated Ink Level tab. A cartridge may be running out of ink even if the graphic shows ink remaining. Lines or streaks always appear in printouts when the cartridges begin to run out of ink. Replace print cartridges that are out of ink or low on ink.
If you do not mind, please rate my help I would greatly appreciate it. Thanks

Black ink is very light


This may well be a printhead problem. I had to replace mine and several other people have posted similar problems. Call Kodak's tech support, and they will walk you through verifying this. They shipped me a new printhead 2nd day air free of charge.

Printer Toolbox Not Recognizing New Black Ink Cartridge


Pop out the cartridge and look inside the printer where the black cartridge goes. There may be punctures in the ribbon cable from the metal wire that rests against the catridge. I have lost 2 6940's to this problem.
