Welcome to the HP Forums!
I see that your HP 7180 will not print in black, and I am happy to help!
For further assistance, I will need to know:
- The Product/Model Number of your printer. Follow instructions in this link. Finding Your HP Product Model Number.
- If the printer is connected, Wireless, Ethernet, or USB.
- If there is any black showing on the diagnostic page. Print the Self-Test Diagnostic Page
- If the power cable is plugged into a surge protector, or directly to the wall outlet. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
- If you are using Genuine HP Ink Cartridges.
- If any of your color cartridges are low or empty.
In the meantime, please take a look through this print quality guide. Streaks or Lines in the Printed Output.
Hope to hear from you soon!

Here are the answers to your questions;
! HP Photosmart C7180 all in one
Regulatory model SDGOB-0605-03
[edited Serial Number by Moderator] Q8192A-x03
The ink gauge shows I have FULL Black Ink
Plugged directly into wall outlet, I checked the power problems section & there were no issues.
Genuine HP ink
Light Magenta looks low on the scale but there is no low warning yet.
I tried print alignment which would failed. It would not print black but the colors were fine & the bird aligned
I tried to print the extended diagnostic page but nothing in black printed.

Thank you for answering my questions, I appreciate it!
The alignment page failing may result in the Magenta being low, I would try to replace the Magenta cartridge with a new one, then try the cleaning and alignment steps again.
Hope this helps!
