Cleaning the Print Head Clean the print head if lines are missing or if horizontal white streaks are present in the printed nozzle check pattern. Cleaning unclogs the nozzles and restores the print head condition. Cleaning the print head consumes ink, so clean the print head only when necessary. 1. Make sure that the power is turned on. 2. Hold down the Stop button until the Alarm lamp flashes twice, then release it immediately. The machine starts cleaning the print head. The cleaning will be complete when the ON lamp lights after flashing. Do not perform any other operations until the machine completes the cleaning of the print head. This takes about 30 seconds. 3. Check the print head condition. To check the print head condition, print the nozzle check pattern. Note • If the problem is not resolved after cleaning the print head twice, clean the print head deeply. 138
