11-7. Black Mark Specifications
Print direction
Note:
1) The cut position shown above is for when memory switch #2 (print start position adjustment) is set to its default setting.
2) The black mark's PCS value must be 0.90 or more.
3) With the factory default setting, the printer may not detect black marks correctly, depending on the paper that you are
using and the printed condition of the black marks.
We recommend that you make adjustments with the paper that you are using.
4) The accuracy of paper feeding to the start position through black mark detection is ±2 mm of the reference print posi-
tion. The printing length accuracy is ±2% of the set value, taking into account the environmental temperature and the
error in the manufacturing process of the platen core. Add a maximum of -5% error to the set value when taking the ser-
vice life into account. If you are using pre-printed paper, pay attention to the print layout.
5) The printing area is as shown in the above diagram when you use black marks.
The top margin consists of approximately 13 mm from the print position to the cut position (auto cutter) and at least
1 mm (8 dot lines) of paper feeding when printing after cut operations. Therefore, the minimum total margin is 14 mm.
Ensure that the margin shown in the above diagram is used to prevent the printing length setting along the paper feed
direction from exceeding the black mark pitch. Otherwise, pages may be skipped.
[Example of printing area setting]
<When the black mark pitch (length A) is 100 mm>
Top margin: 14 mm/Bottom margin: 3 mm + (100 mm × 0.03) = 6 mm
Therefore, the printing length along the paper feed direction must be 80 mm or less.
