cartridge 903XL black original Hp, Printer 6950 doesn't print black

[Nirvanablu]

Hi!

After I changed the black cartridge 903Xl I get some problems to print black pages. I'm using original Hp 903XL.

The first page is printed, but after I have to clean the printer to get a printed black page. It's annoying and also I consume all the toners to clean the printer.

I have no trouble with colour cartridges.

I don't if the printer (6950) is broken or the black cartridgs has manufacturing problems

@Nirvanablu,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More.  I understand you have issues printing in black from your printer. Don't worry I'll be glad to help you out.

To provide you with an accurate solution, I'll need a few more details:

Did you make any changes to your printer?

Does the issue persist when you make a copy from your printer?

Have you installed full feature printer software?

Have you tried printing from a different application?

Have you tried printing using a different ink cartridge?

Excellent description and a great diagnosis done. It is greatly appreciated.

Let's start off by updating the printer firmware. If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Alternatively you can also try to update the printer firmware directly from the printer control panel.

For more details on how to update, please use this link: HP Printers - Updating or Upgrading Printer Firmware

Replace low, empty or faulty ink cartridges on your printer.

Let's start off by performing a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Next thing, I would suggest here is to check the print setting in Windows:

Check the print settings for your print job in Windows 10, 8, Windows 7, or Windows Vista.

1. In the software application you are trying to print from, click File, and then click Print.

   The Print window opens.

2. Open the Properties dialog box.

   Depending on the software application, the button might be Properties, Options, Printer Setup, Printer, or Preferences.

3. Depending on your print job, you might consider modifying the following settings:

   • Paper Type: If you are printing on photo paper, select the type of photo paper you are attempting to print on.

   • Print Quality: If you are dissatisfied with the quality of your printouts, increase the print quality. To print more quickly, decrease the print quality. These options typically include Best, Normal, and Draft modes.

   • Paper Size: If you are printing on a different size of paper than you normally print on, select the correct paper size.

   • Black and White: If you want to print in black and white only, select the grayscale option.

4. After selecting the print settings, click OK to apply the settings, and then click Print.

If the copy comes out bad, then I would suggest you try these steps here: HP OfficeJet 6900 Printers - Black or Color Ink Not Printing, Other Print Quality Issues

If the copy comes out fine, then I would suggest this could be an issue with the printer software. Let's try to do a clean install of the printer drivers.

First, unplug the USB cable from the printer if present.

Go to Control panel – Programs and feature – Select all the HP OfficeJet printer entries and uninstall them.

Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.

Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.

Under print server properties, go to drivers - remove any entry there as well.

Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.

Restart your computer.

Now Click here to download and install the printer software.

Connect the USB cable only when prompted and follow the on-screen instructions to complete the setup.

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!

I hope you have a good day ahead,
