1.1.7 Mark Detection
10 Searching for vertical line
of mark (TP2)
1. When the distances between the marks are known by the procedure for
scale compensation with the setting value “BEFORE”, the head moves in
the Y-axis right direction by “Distance between marks -Length which is
twice the mark size”.
2. The head moves in the Y-axis right direction until the mark sensor turns on
and stops.
3. The head moves in the Y-axis right direction by the distance of HM.
4. The head moves in the Y-axis left direction until the mark sensor turns on and stops.
5. The plotter determines the center of the horizontal line based on the positions of “2” and “4”.
6. Finally the head moves in the Y-axis right direction (for type 1) or Y-axis left direction (for
type 2) by the distance of HM and terminates.
• If the vertical line is not detected even after a search of the maximum printing range,
[ERROR36-C MARK DETECT] appears.
11 Searching for horizontal
line of mark (TP2)
1. The head moves in the X-axis lower direction (for type 1) or X-axis upper direction (for
type 2) until the mark sensor turns on and stops.
2. The head moves in the X-axis lower direction (for type 1) or X-axis upper direction (for
type 2) by the distance of HM.
3. The head moves in the X-axis upper direction (for type 1) or X-axis lower direction (for
type 2) until the mark sensor turns on and stops.
4. The plotter determines the center of the vertical line based on the positions of “1” and “3”.
5. At the end of mark detection, the pen tip moves to the corner of TP1, which is the center of
the vertical line and the center of the horizontal line of TP1.
• If the horizontal line cannot be detected, the plotter determines that the vertical line
detected above is not part of a mark and repeats the procedure from Step 10.
