Inkjet printers need to be used frequently to prevent blocked print head nozzles. You may have blocked print head nozzles.
Try the printer maintenance to clear the printer nozzles.
After several deep cleaning attempts and there is no improvements in the print then a new print head is required. Also try - Removing the print head, run it under hot water for 2 mins, then let soak for 10 min. then used a can of compressed air to dry thoroughly. It may fix the blocked nozzles.
A new print head maybe expensive and it maybe more cost effective to purchase a new printer.

The following may work: remove all the ink supplies. Remove the printhead and soak it for about 5 minutes in 0.5" of very hot water. Gently blot the printhead on a soft damp paper towel to remove the excess water, then replace in the printer and then reinstall the ink supplies.

Follow the instructions below to replace the printheads in the All-in-One product.
