Method
1. Place three 150 mm scales on the exposure glass, and then copy them.
2. Wait at least 3 min. after the paper exits.
3. Use a scale to measure 100 mm against each scale image (x1, x2, x3)
4. Determine the maximum and minimum deviation (%) from the standard.
5. Calculate the difference between the maximum and minimum deviation.
• For example, if the three measurements of the scales are 100.4 mm, 99.5
• Set the scales in the main scan direction (horizontal), copy them, and
• For best results, using at least three scales is recommended.
• If you have only one scale, then you can make three copies with the scale

mm, 100.2 mm, then the difference between the maximum and minimum
values is 0.9 mm (100.4 – 99.5).
then use the same method to determine the variation
