When the print result is blurred, tinted or streaks appear, the nozzles may be clogged or the ink tank almost empty. If the print head nozzles are clogged, print quality can be improved by performing print head cleaning (Cleaning) or print head deep cleaning (Deep Cleaning). You can also check the cleaning results by printing a Nozzle Check Pattern after cleaning the print head nozzles.
Note: If the printed result does not improve even after doing print head deep cleaning, turn off the printer. Then, after 24 hours or later, do print head deep cleaning again.
