Note: Selectors 3 and 4 are applicable to models equipped with cordless handset.
• Selector 2: CR motor control for reducing torque fluctuation (Not used.)
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.
• Selectors 5 through 7: Transmitter level and echo suppression
Transmitter level 0 sets the transmitter volume to a maximum. As the level increases, the
volume decreases. The transmitter level can also be changed by the user switch and its
setting is interlocked with the setting made by these selectors.
Enabling the echo suppression suppresses echoes in both the receiver and transmitter.
• Selector 8: Switching from ink near-empty state (if detected) to ink empty when opening the
scanner cover (Not used.)
If this selector is set to "0," opening the scanner cover in the ink near-empty state ("Ink
low" message) switches to the ink empty state ("Cannot print" message), prompting the
user to replace ink cartridges.
