NOTE
• In most cases, after automatic media registration you must only adjust the elongation and / or
the image shift.
• If there are two or more registration problems, you must solve the problems one by one. First
you correct the registration of each side. Then you correct the front-to-back side registration.
For example, if the image is skewed and there is a problem with the front-to-back side
registration, then you must first adjust the skewed image. If the skewing is correct, you must
improve the front-to-back side registration.
NOTE
If you are unable to recognize which kind of media registration deviation you have (see
Example
1 - Images and Text
on page 81), perform the following actions:
1. Measure the value for the skewed image, diamond shape image and trapezoid image. See
the corresponding sections.
2. Select the deviation with the largest value and correct the deviation. Use the corresponding
manual actions described in this document.
3. Print the verification chart.
4. If the angles in the corners are straight then continue with the next step. If not, repeat step 1 -
3.
5. If needed, correct the image shift and / or elongation. Use the corresponding manual actions
described in this document.
Corrections for Preprinted Media
Introduction
When you use preprinted media, there is a possibility that the image is not at the correct position,
even when the media registration is correct. For example, it is possible that a preprinted line
along an edge of the media covers part of the printed image. In that case you can perform an
image shift for all the jobs that are printed on this media.
Procedure
1.
Print a representative job on the preprinted media.
2.
Measure the distance that the image must shift for the front side and the back side.
3.
In the section [Corrections for preprinted media] enter the values according to the table below.
4.
Click [OK].
5.
Print the job again and check if the image is printed at the correct position.
Values
Settings front side What to enter
[X image shift front ({0})] The image is shifted in X direction (feed direc-
tion) in steps of 0.1 mm (0.001 inches).
[Z image shift front ({0})] The image is shifted in Z direction (perpendic-
ular to the feed direction) in steps of 0.1 mm
(0.001 inches).
Settings back side What to enter
[X image shift back ({0})] The image is shifted in X direction (feed direc-
tion) in steps of 0.1 mm (0.001 inches).
