Selector 2: CR motor control for reducing torque fluctuation

When the CR motor runs, the motor torque may vary so as to cause the head/carriage unit travel
velocity to fluctuate, affecting the print quality. Setting this selector to "0" activates the CR motor
control that regulates the motor drive current to reduce torque fluctuation, running the CR motor
smoothly.
Selector 8: Switching from ink near-empty to ink empty when opening the scanner cover
If this selector is set to "0," opening the scanner cover switches from ink near-empty (if detected) to
ink empty state, prompting the user to replace the near-empty ink cartridge(s) immediately.
