Adjusting the Image Position (C7700 Series / C5700 Series Only)

You can adjust the printed image position, which is misaligned or distorted, by confirming test pages and specifying setting values.

Outputting a Test Page

Print a test page when adjusting the position of images.
1
Press <Change> for <Adjust Image Position>.
2
Press <Output Test Page>.
3
Enter the number of test pages to make  press <Next>.
4
Select a paper source that contains a custom paper type  press <Start Printing>.
A test page is printed.
For information on paper that can be used as test pages, see Paper Available for 2-Sided Copying/2-Sided Printing.
Make sure that a sufficient supply of paper is loaded in the paper source before outputting the test pages.

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.
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.
In case of the example described above, set "+ 0.4" for <Front Side>.
C7700 Series only
Use <-> and <+> in <Front Side> in <Lead Edge (e) Alignment> to enter the value.
C5700 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.
C7700 Series only
Use <-> and <+> in <Back Side> in <Lead Edge (e) Alignment> to enter the value.
C5700 Series only
Enter the value using <-> and <+> in <Back Side>.
5
Perform the test page again, and check the image position  press <OK>.
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>.
6
Press <OK>.

Adjusting Left Edge Alignment of the Image (C7700 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 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.
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.
In case of the example described above, set "+ 0.4" for <Front Side>.
Use <-> and <+> in <Front Side> in <Left Edge (i) 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.
If you print the test page using paper whose vertical side toward the feeding direction is 12" (304 mm) or more in length, the register mark on the left edge will not be printed properly. In this case, measure the length of <i> mark. If the measured length is shorter than 20 mm, enter the difference value with <+>, if the measured length is longer than 20 mm, enter the difference value with <->.
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 (i) Alignment> to enter the value.
5
Perform the test page again, and check the image position  press <OK>.
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>.

Press <OK>.

Adjusting the Zoom Ratio of the Image (C7700 Series Only)

Depending on the paper type, the heat generated by the fixing unit may cause the paper to expand or shrink slightly. In this case, images may also be enlarged or reduced accordingly. This function enables you to set the zoom ratio of the image for each paper, or enlarge the reduced image to match the zoom ratio of the image on the second side of the paper. You can adjust the zoom ratio of the image either by entering the enlargement/reduction ratio, or by entering the value of the test page you measured manually.
1
Check the images on the output test page.
2
Enlarge or reduce images on the <Adjust Image Position> screen.
If you enter the enlargement/reduction ratio (%)
If you enter the value of the test page you measured manually
