Print Position Adjustment
This printer has two print position adjustment modes, “print start position adjustment mode (Mode
A)” and “bidirectional print position adjustment mode (Mode B),” in order to minimize the effects of
variance between individual printers and age-related deterioration. These modes enable fine
adjustment of the print position in accordance with its carrier speed.
The print start position adjustment mode (hereinafter referred to as Mode A) is used to align the print
start positions of the print modes with different print speeds. This mode sets the print start position
constant for any print speed.
The bi-directional print position adjustment mode (hereinafter referred to as Mode B) aligns the
characters in lines printed at the same speed in different directions. This mode sets the optimum
value for each speed.
A change in Mode A affects Mode B. If the Mode A setting has been edited, the Mode B setting will
also require adjustment. The printer, therefore, automatically moves to Mode B after it enters and
exits Mode A. When the Mode A setting has not been edited, you can adjust the print position in
Mode B only.
