detected (Not used.)
0: Empty state detected when main unit
cover opened
1: Nearly empty state maintained when
main unit cover opened
Note:
Selectors 3 and 4 are applicable only to models equipped with cordless handsets.
- Selector 2: CR motor torque variation reduction control (Not used.)
Printing quality may be lowered due to changes in the head/carriage travel speed resulting
from variations in the torque of the CR motor during operation. If selector 2 is set to “0,” the
CR motor drive current will be controlled so as to inhibit variations in torque, resulting in a
smooth CR motor rotation.
- Selectors 5 through 7: Microphone level and echo cancellation ON/OFF (Not used.)
Microphone level 0 is the highest microphone volume setting. The higher the microphone
level, the lower the microphone volume setting. The microphone level can also be adjusted
by means of a user function. In other words, the microphone level depends on the setting
of the user function as well as on the setting by these selectors.
Using the echo cancellation function, it is possible to reduce echoes both during speaking
and hearing.
- Selector 8: Support between nearly empty
→ empty with main unit cover open after
nearly empty detection (Not used.)
If this selector is set to “0,” the nearly empty ink state, if detected, will be replaced by the
empty ink state when the main unit cover is opened, thus prompting the user to replace the
ink cartridge immediately.
