Ink

[bbrown7511]

For some reason all of our HPs quit printing black inl at the same time.  Color prints fine, but wont print black on any of the htree HPs in the office.  This all happened at once with some using HP replacement cartiridges and outher using non-HP.

We followed hte step s to delete and reinstall drivers that did not help.  We do not think it is a driver issue as when you coopy a form on the copy function you get the same results.  Seems to be printer related.

We have been trying to resolve this for days.  HP Support is non-existent and the HP Virtual Assistant is Virtual Usless.  Any ideas on fixing this?

@bbrown7511,

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 see from your post that you are having issues with printing in black from your HP DeskJet Printer. Don't worry we're here to help you.

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

Have you recently made any changes before the issue started?

Did you try to update the printer firmware? Have you tried to align the cartridges?

Have you tried to check the print settings?

Have you tried to print the self test page or print quality test report?

Have you tried to check with the old ink cartridges?

In the meantime, let's try these steps here: 

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. once done, restart the printer.

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

If the issue persists, I would suggest here is to do 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.

If you’re running Windows, I would start by checking the installed printer software by downloading and running the HP Print and Scan Doctor. This tool can diagnose and fix many printing and printer software related issues. Please use this link to help you with that information: http://hp.care/2biN2XE 

I would suggest here is to Print the Print Quality Diagnostic Report. 

If the diagnostic report fails then I would suggest you follow the steps once again to clean the ink cartridge contacts 

Alternatively you can try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

If the copy comes out bad or the Print quality diagnostic report fails, then I would suggest here is to follow the steps suggested in the support document for - HP DeskJet 2600 Printers - Color or Black Ink Not Printing

If you have already tried the steps and nothing has helped in that case, I would suggest here is to try with the old ink cartridges and check if that works.

If the old ink cartridges too does not work then this is more likely a printer hardware. 

If the old ink cartridges work then it could be an issue with the new ink cartridges being defective.

I will share you a private message with details. Please watch your inbox for more information.

Let me know if this helps!

Have a great day ahead! 🙂
