NOTE:
When "0.0 V" is set for this
parameter, it is automatically
corrected to 1.0V (default)
after the power is turned OFF
then ON.
NOTE:
When "0.0 V" is set for this
parameter, it is automatically
corrected to 1.4V (default)
after the power is turned OFF
then ON.
(8) RBN ADJ.<BK>
When the ribbon is slack or wrinkled and printing is affected, fine
adjust the ribbon motor torque.
(9) THRESHOLD <REFL.>
When you perform a threshold setting for the reflective sensor (Black
mark sensor) and found the threshold needs to be adjusted, set a fine
adjustment value.
This menu is accessible directly from the Threshold Setting Mode so that
the threshold can be manually set right away.
Manually set threshold = Peak voltage – The value set here
For details, refer to Section 2.10.
(10) THRESHOLD <TRANS.>
