• Selector 1: Uneven printing correction for upper and lower ends of the nozzle
If performing the correction lowers the print quality due to wrong nozzle property data, set
this selector to "1" to disable the correction function.
• Selector 5: Jam reduction paper feed mode
Setting this selector to "1" lowers the paper feeding speed when the recording paper passes
along the star wheels for reduction of jams.
• Selectors 6 through 8: Adjustment of print head drive voltage rank
This selector regulates the print head drive voltage rank for adjusting the ink drop amount.
If the black section printed on glossy paper is greenish or the printed ink does not dry
quickly, increase the print head drive voltage rank to decrease the ink drop amount; if it is
reddish, decrease the rank to increase the ink drop amount.
