Troubleshooting
Printhead not recognized by the printer
Ensure the printhead is correctly seated in its carriage. Try removing and reinserting it. Check the electrical contacts on both the printhead and the carriage for any debris and clean gently with a lint-free cloth if necessary. Restart the printer.
Missing or incorrect colors (Magenta or Cyan)
Perform a printhead cleaning cycle through the printer's control panel. If the issue persists, ensure the correct printhead is installed in the correct slot. The printer may need to re-align the printheads after installation.
Streaks or lines in prints
Run a printhead cleaning cycle. If the problem continues, check the printhead nozzles for clogs. A gentle cleaning with a recommended solution might be necessary, or the printhead may need replacement if severely clogged.
Low print quality or faded colors
Verify that the ink levels are sufficient (though this is a printhead, it relies on ink). Ensure the correct print media type is selected in the printer settings. Run a printhead alignment and calibration.
