Setting Compensation (Only in Real 10 Mode)
To adjust the printing magnification used in printing in the Real 10 mode, follow the procedures below.
1
Open the [SETUP MENU: ADDITIONAL] screen and
press the [PRINT TEST] button in the [PRINTER
(PictBridge)] area to print an object image.
An image with the overlaid scale in pixels is printed.
2
Physically measure the dimension of the scale on the
print.
Example: Measure distance between 0 and 500 pixels.
3
Use the following conversion formula to calculate
dimension of the scale on the object from reading of the
scale (in pixels).

500
1000
Conversion formula:
•
Dimension of scale on object
Reading of scale (in pixels) X Pixel size of image pickup device
Optical magnification (objective lens magnification X relay lens magnification)
Example of calculation:
Reading of
scale = 500 pixels

Press the [CMP(50-150%)] button and enter scaling
ration compensation value.
When this button is pressed, a keypad appears. Enter a
desired number and press the [ENTER] key.
Adjust magnification so that the following equation is true.
Dimension of the scale on the print / Dimension of the
scale on the object = Magnification factor of optical
equipment
