4.2.24 PHOTO SENSOR
Outline
An error between the pen tip and photo-sensor for mark detection is compensated automatically, or the adjustment
value is checked.
For the auto-compensation ([ADJUST:POSITION]), the mark is drawn by a pen then detected by the sensor to com-
pensate automatically.
For the adjustment value check ([ADJUST:DETECT]), the function of Mark sensor is checked by the reciprocating
operation on a single line. The check is not required in the field since electric instruments such as an oscilloscope, tes-
ter or the like are required for the check.
Adjustment procedure
1. Set the media, and set the specified pen to the Tool holder.
2. Select [#ADJUST(CUT)] -> [PHOTO SENSOR].
Press the [ENTER] key.
3. Press the [ENTER] key to draw the mark.
* An error is indicated if the sheet is undetected.
After the drawing, the mark detection is executed twice. If the
read values of the twice are less than 0.1mm, the reverse mark
on the basis of the mark-origin detected is drawn, and the pen
tip moves to the mark-center.
In the case of 0.1mm or larger, it is retried up to 10 times.
4. Check if the corner of reversed mark overlaps with the mark
corner and the lines are straight in vertical and horizontal and
the tip of pen stays at the center of mark.
* If any displacement is observed, readjust it since the
detecting may not be correct due to the sagging of sheet or
so.
5. Press the [ENTER] key twice to register the set value then end.
Before this adjustment, be sure that “PEN STROKE (4.2.3)” is proper or have been already adjusted.
