2.4 Black Mark Specifications
Print Direction
<Notes>
1) The cutting position shown in the figure above is a default setting for the print starting position offset
value of memory switch 2 in section 15.3.3.
2) The PCS value of black marks should be min. under 0.90.
3) Printing top of form position precision attained through the detection of the black mark is ±2 mm with
regard to the standard printing position. For printing lengths, it is 2% in the initial status with regard to
the set value, because of the difference in precision caused by the ambient temperature and platen
diameter formation. Considering life, a difference of up to 5% of the set values is considered. The print
layout should be carefully considered also for the paper used in a pre-print.
4) When using a black mark, set the print range to the usable range shown in the drawing above.
Set the top margin to an approximate distance of 13 mm from the printing position to the cutting position
(the auto-cutter), and when cutting the paper after printing, apply a paper feed of at least 1 mm (8-dot
line) to give the margin at least a total of 14 mm.
Always provide the margin shown above so that the black mark pitch is not exceeded in the set values
for print range in the print feeding direction. If a margin cannot be provided, it is possible that pages will
be skipped.
Example Printing Range Setting
• When Black Mark Pitch (Dimension A) is 100 mm:
Top Margin: 14 mm/Bottom Margin: 3 mm + (100 mm x 0.03) = 6 mm
The print range of the paper feed direction should be max. 80 mm.
