Up to Bi-D adjustment patterns No. 1 ~ 3, by deciding the value
input from the panel, the adjustment results are printed out, so it
is possible to check the adjustment results visually, but for Bi-D
adjustment pattern No. 4, even if you decide a value to input
from the panel, a printing pattern that reflects the adjustment
results is not printed, so the adjustment results cannot be
checked visually. Therefore, if you are confirming the
adjustment results for adjustment values by printing pattern, the
following adjustment program becomes necessary.
* Program Transfer Utility: Pout3.Exe
* Program Name:Bid333.prn
The program transfer method is as follows.
1) Confirm that the printer is in the Pause state.
2) Move to the adjustment program
3) Input “POUT__BID333.PRN.”
4) Press the Enter key.
Through the above operation, a total of 9 blocks of printing
patterns are printed out in each color. The results from the
adjustment values input in the Adjustment mode are positioned
in the center pattern of the 9-block pattern of each color.
