There could be a few reasons why an Epson printer is not printing color properly even when the ink levels are full:
- Clogged printhead nozzles - The printhead nozzles could be partially clogged, preventing the proper amount of ink from being dispensed. This is common if the printer hasn't been used in a while. Running cleaning cycles or manually cleaning the printhead may help unclog the nozzles.
- Ink cartridge issues - One or more of the color ink cartridges could be defective or not seated properly. Try removing and reinserting the color cartridges to make sure they are properly installed. Replace any cartridges that seem faulty.
- Printer driver settings - The printer driver settings may have an option enabled to only print black ink or grayscale. Check the print settings to make sure color is enabled.
- Color ink printout alignment - The color ink nozzles may need alignment if text or images appear blurry. Run an alignment procedure from the printer menu to realign the color ink placement.
- Bad color ink cartridge contacts - The cartridge contacts may be dirty or damaged, preventing proper communication. Clean the contacts with a soft cloth. If needed, replace the affected cartridges.
- Defective color ink channels - Internal parts like tubes or valves could be damaged, preventing ink from reaching the printhead properly. This would require printer repair or replacement.
So in summary, try cleaning the printhead, check cartridges and drivers, run alignments, clean contacts, and inspect internal parts to resolve Epson color printing issues. Let me know if the problem persists after trying these steps!
