Warm Tips: 1. Please click "OK" or "Yes" to continue if printer shows messages such as "No Ink" or "Non-Genuine/ Original". 2. Better to keep the printer on for continuous usage. Otherwise, please switch the printer on weekly because printer will automatically clean the print head once it detects ink shall dry, otherwise the ink might dry on nozzle then clog the print head.
