3. PCS value
The PCS value of the black marks that will be printed should be a minimum
of 0.90 (90%).
Note:
If the PCS value of the black marks does not meet the specification listed
above, page skipping and page length detection errors may occur. To avoid
problems, make sure that the specified PCS value is used.
4. Top margin (dimension B)
When setting the printing area, leave a sufficient top margin between the
cutting location and the top of the printing area.
When not using reverse paper feeding, a top margin of at least 12 mm is
recommended: 11 mm for the distance between the thermal head heating
element and the cutting location, and 1 mm for the paper feeding that occurs
due to the vibrations when the motor starts.
Note:
1) If the top margin is insufficient, page skipping errors may occur. To avoid
problems, set the top margin carefully.
2) The printing area setting should not exceed the black mark pitch.
5. Bottom margin (dimension C)
When setting the printing area, leave a sufficient bottom margin between the
bottom of the printing area and the following black mark.
When setting the bottom margin, consider the printing precision of the black
mark pitch, TOF printing precision (±2 mm from the standard printing
location), ambient temperature at the installation location, and the amount of
wear of the printer parts. It is recommended to set the printing area to achieve
the following bottom margin.
Bottom margin (dimension C) 3 mm + (dimension A × 3%)
Note:
1) If the bottom margin is insufficient, page skipping errors may occur. To
avoid problems, set the bottom margin carefully.
2) The printing area setting should not exceed the black mark pitch.
