Cleaning the Print Head deeply consumes more ink than the standard cleaning of the Print Head, so clean the Print Head deeply only when necessary. 1. Make sure that the power is turned on. See Operation Panel. 2. Clean the Print Head deeply. (1) Press the Menu button repeatedly until Maintenance appears. (2) Use the (-) or (+) button to select Deep cleaning, and press the OK button. The machine starts cleaning the Print Head deeply. Do not perform any other operations until the machine completes the deep cleaning of the Print Head. This takes about 1 minute 30 seconds. 3. Check the print head condition. See Printing the Nozzle Check Pattern. If the problem is not resolved, turn off the power and clean the Print Head deeply again after 24 hours. Do not disconnect the power plug when turning off the power. If the problem is still not resolved, replace the FINE Cartridge with a new one. See Replacing a FINE Cartridge. If the problem is still not resolved, contact your service center. Page top
