Dear Adrienne,First make sure that the black ink is not empty. If you are sure the black ink is full enough you need to check the print head condition. The print head may be clogged or faulty.
To fix the clogged print head,please perform the following step:
- Print the nozzle check pattern, access the following menu on LCD: Menu>Maintenance>Nozzle Check. The good nozzle pattern should like below sample image.
- If the print head nozzle missing some color (i.e Black) the perform print head cleaning: Menu>Maintenance>Cleaning. Then print the nozzle check pattern again. Note: you may repeat this step up to 3 times.
- If the problem still remain,then you should perform Deep Cleaning: Menu>Maintenance>Deep Cleaning.
If you have perform the above steps but the problem still the same,please check whether the black nozzle missing partially or totally. The faulty Purge Unit (ink pump) may cause the same problem. I mean the purge unit does not work properly so the ink cannot flow. Good luck :)
