Top margin (Dimension B)
Set the printing range, leaving plenty of top margin from the cutting position.
When not using reverse paper feed, a top margin with a minimum total of 11 mm of the distance from the
thermal head heating elements to the cutting position, and paper feed amount of 1 mm considering vibrations
when starting the motor, results in a recommended top margin of 12 mm.
Note 1: If the top margin is not sufficiently taken, problems, such as a page being skipped, can occur. So, you
must set for plenty of top margin.
Note 2: The setting of the printing range should not exceed the black mark pitch.
5.
Bottom margin (Dimension C)
Set the printing range leaving plenty of bottom margin from the trailing edge of the printing range to the black
mark.
It is necessary to consider the printing precision of the black mark, the printing TOF accuracy (
±
2 mm of the
standard printing position), the setup ambient temperature of the printer, and part wear-out to set the bottom
margin. It is recommended that the following bottom margin be secured to set the printing range.
Bottom Margin (Dimension C)
≥
3 mm + (Dimension A x 3%)
Note 1: If the bottom margin is not sufficiently taken, problems, such as a page being skipped, can occur. So,
you must set for plenty of bottom margin.
Note 2: The setting of the printing range should not exceed the black mark pitch.

Example Setting of the Printing Region
The following shows a printing range setting example when not reverse feeding recording paper.
When Black Mark Pitch (Dimension A) is 100 mm:
The top margin is set to 12 mm.
The bottom margin is set to 3mm + (100 mm x 0.03) = 6 mm.
According to the above, it is necessary to set the printing range to less than 100 mm – 12 mm - 6 mm = 82
mm.
Note 1: Print TOF positioning precision using the black mark detection is ±2 mm of the standard printing position.
For printing length, it is ±2% of the setting value, in consideration of the differences of the initial ambient
temperature and forming precision of the platen diameter. When the life of the printer is considered, the
print layout should be carefully planned if using paper that has been pre-printed. An error of up to -5% of
the setting values should be considered.
Note 2: If you have any questions regarding how to set the printing range for the black mark, consult with STAR
Micronics.

Sensor
Adjustments
It is recommended to adjust the black mark sensor position if using black marks.
