Correct Distortion (Trapezoid)
This setting enables you to correct the image shape by equalizing the length of the right and left side of the printing area when the image is printed like a trapezoid.
1.
Press
(Settings/Registration).
2.
Press [Preferences] → [Paper Settings] → [Paper Type Management Settings].
3.
Select the paper type that you want to edit from the list → press [Details/ Edit].
4.
Press [Change] for <Adjust Image Position>.
5.
Press [Do Not Use Scanner].
6.
Press [Set Details] → [Corr. Distort. (Trapezoid)].
If you want to enter the values of the test page you measured manually:
Press [Output Test Page].
Enter the number of test page to make → press [Next].
|
NOTE
|
|
If the image position varies greatly, the accuracy of correction may be improved by printing several test pages and using an average of the measured length.
|
Select a paper source that contains a custom paper size → press [Start Printing].
The test page is printed.
Measure the length of the 'b' and 'h' marks on the test page.
The mark 'b' is printed on the right side and the mark 'h' is printed on the left side of the feeding direction.
Example: 'b' = 360.0 mm, and 'h' = 355.5 mm
Return to the <Correct Distortion (Trapezoid)> screen → enter the measured length of [b] and [h] for front and back sides.
Using the following two numerical values and "c = 250.0", a device adjusts the length to correct distortion on the printing area.
|
[b]:
|
Enter the measured length of 'b' mark on the test page.
|
|
[h]:
|
Enter the measured length of 'h' mark on the test page.
|
Following the example, enter 360.0 for [b] and 355.5 for [h].
The difference between 'b' and 'h' (0.5 mm) is corrected.
Press [OK].
Print a test page again and check the image position as needed. If you need to make a further adjustment, repeat steps above.
If you correct the position using any printed images:
Check the image position on the output paper.
Example: 'c' = 200.0 mm, 'b' = 300.0 mm, and 'h' = 299.5 mm
Measure the following length on the output paper and enter the measured length.
Using the following three numerical values, a device adjusts so that the distorted printing area may be corrected.
|
[c]:
|
Enter the measured length from the left side lead edge of the printing area to the right side lead edge of the printing area.
|
|
[b]:
|
Enter the measured length from the right side lead edge of the printing area to the right side tail end of the printing area.
|
|
[h]:
|
Enter the measured length from the left side lead edge of the printing area to the left side tail end of the printing area.
|
Following the example, enter 200.0 for [c], 300.0 for [b], and 299.5 for [h].
The difference between 'b' and 'h' (0.5 mm) is corrected.
Press [OK].
Print a test page again and check the image position as needed. If you need to make a further adjustment, repeat steps above.
7.
Press [OK] → [OK].

NOTE
|
|
To restore the accumulated value, press [Restore Initial Settings].
If register marks are printed on the output paper, the printed area is equal to the area inside the register marks.
