Adjusting Lead Edge Alignment of the Image

This setting enables you to adjust the image position, by checking whether the register mark and the image at the leading edge toward the feeding direction are aligned on the test page.
1
Check the position of the lead edge image on the front side of the test page.
8700 Series only
In the example below, adjustment is required because the center line of the register mark is 4 pixels outside the edge of the test page. Follow the procedure described below to adjust the position of the lead edge image on the front side of the test page.
The test page with "1" printed on it is the front side.
 
6000 Series only
In the example below, adjustment is required because the center line of the register mark is 0.4 mm outside the edge of the test page. Follow the procedure described below to adjust the position of the lead edge image on the front side of the test page.
The test page with "1st side" printed on it is the front side.
2
In the <Adjust Image Position> screen, enter the value confirmed on the test page that aligns the center line of the register mark with the edge of the paper.
For the test page in the procedure above, set <Front Side> to 4 pixels or 0.4 mm.
8700 Series only
Use <-> and <+> in <Front Side> in <Lead Edge Alignment> to enter the value.
6000 Series only
Enter the value using <-> and <+> in <Front Side>.
<+>
Press when the center line of the register mark is located outside the edge of the test page (the center line of the register mark is NOT printed). The image is shifted to the backwards as seen from the feeding direction of the paper, according to the entered value.
<->
Press when the center line of the register mark is located inside of the edge of the test page. The image is shifted to the forwards as seen from the feeding direction of the paper, according to the entered value.
3
Turn over the test page  check the lead edge image on the back side of the test page.
4
Enter the value confirmed on the test page that aligns the center line of the register mark with the edge of the paper.

Repeat the correction again, if necessary.
When you open the <Adjust Image Position> screen again after you close that screen by pressing <OK>, the values on screen are returned to <0>. However, the adjusted value is still effective. If you repeat steps, read off the value of register marks from new test page and input the new value.
To restore the accumulated value, press <Restore Initial Settings>.

Adjusting Left Edge Alignment of the Image (8700 Series Only)

This setting enables you to adjust the image position, by checking whether the register marks on the test page align with the image at the left edge of the paper toward the feeding direction.
1
Check the position of the left edge image on the front side of the test page.
In the example below, adjustment is required because the center line of the register mark is 6 pixels inside the edge of the test page. Follow the procedure described below to adjust the position of the left edge image on the front side of the test page.
2
In the <Adjust Image Position> screen, enter the value confirmed on the test page that aligns the center line of the register mark with the edge of the paper.

Use <-> and <+> in <Front Side> in <Left Edge Alignment> to enter the value.
<+>
Press when the center line of the register mark is located outside the edge of the test page (the center line of the register mark is NOT printed). The image is shifted to the right as seen from the feeding direction of the paper, according to the entered value.
<->
Press when the center line of the register mark is located inside of the edge of the test page. The image is shifted to the left as seen from the feeding direction of the paper, according to the entered value.
3
Turn over the test  page check the left edge image on the back side of the test page.
4
Enter the value confirmed on the test page that aligns the center line of the register mark with the edge of the paper.
Use <-> and <+> in <Back Side> in <Left Edge Alignment> to enter the value.
5
Perform the test page again, and check the image position  press <OK>.
Repeat the correction again, if necessary.
If you output a test page on a sheet of paper in which the length of the side perpendicular to the feeding direction is 305.1 mm or longer, the "A1" mark is printed 12.5 mm inside. In this case, draw a line that is 12.5 mm inside the left edge and parallel to the left edge of the paper. Then, check that this line matches the center line of the "A1" mark. If the two lines do not match, perform the image position adjustment.
*1 12.5 mm
*2 305.1 mm or longer
In the example above, adjustment is not required because the center line of the "A1" mark matches the line drawn 12.5 mm inside the edge of the paper.
When you open the <Adjust Image Position> screen again after you close that screen by pressing <OK>, the values on screen are returned to <0>. However, the adjusted value is still effective. If you repeat steps, read off the value of register marks from new test page and input the new value.
