5.2.3.5 Check Nozzle

Check the print result to see if the head nozzles discharge ink properly and if there is any alignment error. If ink discharging from the nozzles is faulty or there is any alignment error, execute cleaning in this item and perform checking again. If there is no ink remaining, the printer requests the installation of ink cartridges. When paper has been set and there is ink, the printer prints the head nozzle check pattern.
