Officejet Pro 6835 Won't print black after changing to new ink cartridge

[Kimberly19]

Printer worked fine until I had to swap out the black ink cartridge when it ran low.  I used a genuine HP XL cartridge.  There is absolutely no black ink being produced.  All other colors are printing fine.  I have both cleaned and aligned the printheads, reset the printer (unplugged while on - rest - plug back in),  plugged directly into wall, changed all color cartridges to new, and tried a second new black cartridge,  all with no impact on the problem.

@Kimberly19,

Welcome to HP Support Community,

This looks like a possible hardware failure, I would recommend you contact our HP support team to get the printer service or possible upgrade options.

Select the product type.

Enter the serial number of your device or select let HP detect your product option.

Select the country from the drop-down.

You should see the HP phone support number or Chat option listed.

Let me know how it goes and you have a great day!
