My HP 6830 printer just stopped printing black ink

[Jas08k]

I have HP Officejet Pro 6830 printer.  It was low on black ink, so I replaced cartridge.  Ever since then it won’t print black ink, even though my printer is saying black ink is full.  I tried turning off and pressing power button for 15 seconds and still not working.

Welcome to HP support community.

Did you make a copy and check if that prints fine?

Meanwhile:

Print a Print Quality Diagnostic Page

1. Load plain white paper into the tray.

2. On the printer control panel, swipe the display to scroll to Setup, and then touch the Setup icon . The Setup menu displays.

3. Swipe the display to scroll to Reports, and then touch Reports.

4. Touch Print Quality Report. The printer prints the report.

   

If that does not print in black, follow the below steps:

Make sure the ink cartridges are properly vented and seated correctly.

1. Press the Power button to turn on the printer, if it is not already on.

2. Place your fingers into the slot on the left side of the printer, and then gently lift up to open the cartridge access door. The carriage moves to the cartridge access area. Wait several seconds until the carriage is idle and silent before you continue.

   

3. Press the tab inward on the front of the old cartridge to release it, and then pull up on the cartridge to remove it from the slot.

   

4. Examine the vent area above the HP logo on the top of the cartridge.

   

5. If the cartridge still has the orange pull-tab attached, pull to remove it.

   

6. If the vent is clogged, use a straight pin to gently remove excess adhesive from the vent.

7. 1. 

      Clogged vent

   2. With a straight pin, gently remove excess adhesive from the vent

   3. Unclogged vent

8. Turn the cartridge so that the cartridge contacts face downward, and then match the label color with the color dot on the carriage.

9. Slide the cartridge into its slot, and then gently press the cartridge down until it clicks into place.

   

10. Repeat these steps to inspect the vents on each of the cartridges.

11. Make sure that each cartridge is firmly installed in its slot. Run your finger along the top of the cartridges to feel for any that are protruding, and if any are, press down firmly until each cartridge snaps into place.

12. Close the cartridge access door.

    

Clean the printhead

1. Load plain white paper into the tray.

2. On the printer control panel, swipe the display to scroll to Setup, and then touch the Setup icon .

3. Swipe the display to scroll to Printer Maintenance, and then touch Printer Maintenance.

4. Touch Clean Printhead.

   A test page prints.

5. Examine the test page.

   • If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. If necessary, repeat these steps for the third cleaning cycle.

   • If the print quality is acceptable, touch Done.
