Making Printer Settings Maintenance Menu Using the Maintenance menu, you can specify printer maintenance settings for adjusting settings such as gradation and density. Nozzle Check You can print a test pattern to check whether the inks are being correctly ejected from the print head nozzles. Head-cleaning You can clean the print head. Clean the head if certain colours are not printed or are printed faintly. Head cleaning consumes ink. Head-flushing You can clean the print head more thoroughly. Because head flushing consumes more ink than head cleaning, do it only if the print head cannot be cleaned properly by head cleaning. Head Position If bidirectionally printed lines are vertically misaligned, or if printed images are blurred, print the test pattern and adjust the print head alignment. Adj.Paper Feed If printed lines are horizontally misaligned or if images are printed unevenly, print the test pattern and adjust the paper feed setting. Registration Print the test pattern and align the point where printing starts for each paper feed tray. Key Repeat You can enable or disable repetition of an operation if a key on control panel is pressed continuously. Paper Feed Test To remove moisture from inside the machine, you can eject a sheet of paper without printing anything on it. De-condensation To remove moisture from inside the machine, you can eject three sheets of paper without printing anything on them. 50
