APPENDIX
A-8. Black mark specifications
<Remarks>
1.) The cut position shown above is when the print starting position correct value
for Appendix F: memory switch 2 is the default setting.
2.) The black mark’s PCS value must be 0.90 or more.
3.) Note that accuracy of starting printing with the black mark sensor must be
within ±2 mm of the standard printing positions, the printing length must be
within ±2 mm of the set value in consideration of discrepancies occurring in
the processing accuracy of the platen diameter and environmental tempera-
ture in the initial state, and a -5% error margin against the set value must be
taken into account in consideration of life expectancy and attention paid to the
print layout when using pre-printed paper.
4.) The printing area must be within the usable range shown in the above diagram
when using black marks. With regards to the top margin, approximately 13 mm
is established between the print position and the cut position (auto cutter,) and
the paper is fed through 1 mm or more (eight dot lines) if printing is performed
after the cutting operations, making a total of 14 mm or more for the margin.
Ensure that the margin shown in the above diagram is used to prevent the
printing area value in the paper feed direction from exceeding the pitch of the
black mark. Note that if this margin is not used, it may result in pages being
skipped and other defects.
[Example of the printing area setting]
<When the pitch of the black mark (dimension A) is 100 mm>
Top margin: 14 mm / bottom margin: 3 mm + (100 mm

From this, it is clear that the printing area in the paper feed direction must be
80 mm or less.
