SOURCE: new black print cartridge not working

I only use refill HP inks. When the cartridge prints gray instead of sharp black it means the ink well is clogged. Yes, that can happen on a new cartridge. Sometimes it happens when they put too much ink in the cartridge, or even heat can make it not work. Also streaking black lines is the problem of the ink not coming out properly. Easiest thing to do is go to a refill station like Cartridge World and have them test it or clean it out. You can also make sure the printer, not the cartridge is clean. Ink builds up an pools. Get some Q-Tips and clean up all that spilled ink. Sometimes in the software it says you can clean the print head, do that too.

SOURCE: Printer Cartridges won't align C4180 printer

Printer keeps trying to perform an alignment after installing a new black ink cartridge fix:

1. Unplug USB
2. Turn printer off
3. Wait 10 seconds
4. Remove paper from paper tray so printer has no paper to print on
5. Turn printer on
6. Printer messages to insert paper in paper tray
7. Press and hold “Setup” and “ Cancel” buttons and press “OK”
8. Should be good until next black ink cartridge change.

I never heard of that for the C7180 all-in-one. Remove the ink cartridges. Dampen a rag with water. Slide the cartridges across the rag until you see ink. If yes, than good. Grab a couple of cotton swabs & drip a couple drops of alcohol onto a tip. Wipe the copper contacts off on the ink cartridges. Do the same to the contacts within the ink carriages. Replace the ink into the carriage.
From your computer, open Printer and Faxes. Make sure your HP C7180 all-in-one printer has a check mark next to it. If not, left click the C7180 once so its high-lighted. Than click "File" in the upper left corner of the window. Left click, "Set as Default printer". Than right click once on the C7180 & slide to & left click on Properties. In the next window click "Printing Preferences", Another window will open. Left click the "Services" tab. Click the "Service this device" button.
Than click, "Clean the Print Cartridges". When the printer finishes, click "Print a Test Page", button. (If you do not see ink on the test page than your ink cartridge are too clogged & you'll have no choice but to replace them).
Using the damp rag loosens possible clogged/dried up ink. Cleaning the contacts with alcohol removes oil from touching the copper contacts with your fingers, also removes dust. Always keep a cover over your printer when not in use. My current ink cartridges are at least 1+ year old. HP & other manufactures do use tracking software to monitor your ink cartridges in this fashion. If you remove an empty cartridge & re-fill it & replace the cartridge the software knows. Each cartridge has a tiny chip attached to it.
The internal software knows when you fill a ink cartridge & can shut down your ability to print. Forcing you to buy new ink cartridges. Below is the HP link for your C7180 printer.

SOURCE: The printer doesn't reset after putting in new cartridges

did you take off that piece of plastic that coverred your new ink cartridge contact?

SOURCE: HELP PLEASE

Remove one cartridge and close the access door. If the cartridge light goes off, the bad cartridge has been removed. If the light continues to blink, remove the other cartridge and reinstall the first one. If the light goes off, the cartridge in the printer is the good one.
