Adjusting the Print Position by Entering Measured Values
Document number: A0YC-256
Measure the shift amount of the image on the test page or any printed page, and enter the measured values to perform adjustment. You can select the adjustment items according to the problems.
When you want to adjust multiple items, you can more easily align the print position on both sides of the paper by performing the adjustments in the following order:
When printed image is slanting diagonally (Correct Image Misalignment)
When printed image is distorted like a parallelogram (Correct Distortion (Parallelogram))
When printed image is distorted like a trapezoid (Correct Distortion (Trapezoid)) (C7100 Series only)
When printed image is enlarged or reduced (Adjust Image Size)
When image position is shifted left or right according to the feed direction (Adjust Left Edge Alignment)
When image position is shifted toward the leading or trailing edge according to the feed direction (Adjust Lead Edge Alignment)
* You can also adjust the image printed on Long Sheet paper. * You cannot perform Adjust Image Size using any other printed page.
* You can skip this step if the paper is already registered. Proceed to Step 2.
Step 2: Printing a Test Page
Print a test page on both sides of the paper using the control panel. Usable Paper for 2-Sided Printing You cannot print the test page using Remote UI from a computer.
* If you want to perform adjustment for Long Sheet paper, print the dedicated test page on both sides of the paper, and proceed to Step 3. Step 3: Adjusting by Entering Measured Values
You can download the dedicated test page from the online manual site.
The front side of the test page has "1st side" printed on it.
To ensure accurate adjustment results, print the Long Sheet test page at 100% magnification.
Print the test page on the actual Long Sheet paper to be used.
Depending on the size of the paper to be printed, the "b," "f," "h," and "j" indicators may be printed multiple times. Perform adjustment for the locations closest to the trailing edge of the paper.
Set the number of test page copies, and press [Next].

Select the paper source loaded with the paper to be adjusted.
4
Press [Start Printing].
The test page(s) is printed.
Step 3: Adjusting by Entering Measured Values
Check both the front and back sides of the test page or a printed page to determine whether the print position is shifted. If the position is shifted, measure each length on the front and back sides, and perform adjustment based on the measured values.
1
Measure each length on the test page or a printed page.
Measure the lengths on the front side and back side. The front side of the test page has "1st side" printed on it.
On the test page, the "i" indicator is printed at the left side of the leading edge and the "j" indicator is printed at the left side of the trailing edge, according to the feed direction.
When you use a printed page other than the test page, also measure the length of "h."
On the test page, the "a" indicator is printed at the right side of the leading edge and the "g" indicator is printed at the left side of the leading edge, according to the feed direction.
When you use a printed page other than the test page, also measure the length of "c."
If part of the image is not printed on the test page (standard size), measure the lengths of "f/2" (half the length of "f") and "d/2" (half the length of "d"). Compare these measured values to the prescribed values (f/2: 180.0 mm, d/2: 125.0 mm) to calculate the enlargement or reduction ratio.
* If you print the test page on paper smaller than 270.0 mm x 380.0 mm (10 5/8" x 15"), part of the image will not be printed on the paper.
If part of the image is not printed on the test page (Long), follow the procedure below to compare the values and calculate the enlargement or reduction ratio.
If part of "d" is missing, measure the length of "d/2" (half the length of "d"), and compare it to the prescribed value (125.0 mm).
If part of "f" is missing, measure the length of "f" closest to the trailing edge, and compare it to the corresponding prescribed value (450.0 mm, 550.0 mm, or 650.0 mm).
* If you print the test page on paper smaller than 270.0 mm x 762.0 mm (10 5/8" x 30"), part of the image will not be printed on the paper.
When you use the test page, you can also perform adjustment by checking the value of the indicator at the bottom left. When you check the value of the indicator at the bottom left, proceed to Step 2.
When you use a printed page other than the test page, "i" is at the left side of the leading edge according to the feed direction.
When you use the test page, you can also perform adjustment by checking the value of the indicator at the leading edge according to the feed direction. When you check the value of the indicator at the bottom left, proceed to Step 2.
When you use a printed page other than the test page, "e" is at the leading edge according to the feed direction.

Enter the measured values in each item for the front side and back side.
Press [Adjust Using Test Page], enter the measured values in [f] and [d], and press [OK] [OK].
For a Long test page, perform the calculation below and enter the value in [f].
Prescribed value (360.0 mm) ÷ Measurement position (450.0 mm, 550.0 mm, or 650.0 mm) x Measured "f" value
When Entering the Enlargement or Reduction Ratio
If part of the image is not printed on the page in Step 1, enter the calculated enlargement or reduction ratio in [Zoom (f)] and [Zoom (d)], and press [OK].
To enlarge or reduce the print image in the direction parallel to the feed direction, enter the value in [Zoom (f)].
To enlarge or reduce the print image in the direction perpendicular to the feed direction, enter the value in [Zoom (d)].
You can press [±] to switch the entered value between positive and negative.
In [Left Edge (i) Alignment], enter the amount of difference between the prescribed value (20.0 mm) and the length of "i" measured in Step 1, and then press [OK].
If the measured length of "i" is 21.5 mm, enter -1.5 mm.
If the measured length of "i" is 18.5 mm, enter +1.5 mm.
You can press [±] to switch the entered value between positive and negative.
When Adjusting Based on the Indicator at the Bottom Left of the Test Page
Check the amount of the shift between the paper edge and the center line of the indicator, enter the corresponding value, and press [OK].
When the center line of the indicator is outside the paper edge (when the center line of the indicator is not printed on the page), set a positive (+) value. The print position moves toward the right edge according to the feed direction. Example: If the center line of the indicator on the front side is 0.4 mm outside the edge of the paper, set [Front Side] to "0.4 mm."
When the center line of the indicator is inside the paper edge, set a negative (-) value. The print position moves toward the left edge according to the feed direction. Example: If the center line of the indicator on the front side is 0.6 mm inside the edge of the paper, set [Front Side] to "-0.6 mm."
In [Lead Edge (e) Alignment], enter the amount of difference between the prescribed value (20.0 mm) and the length of "e" measured in Step 1, and then press [OK].
If the measured length of "e" is 21.0 mm, enter -1.0 mm.
If the measured length of "e" is 19.0 mm, enter +1.0 mm.
You can press [±] to switch the entered value between positive and negative.
When Adjusting Based on the Indicator at the Leading Edge of the Test Page
Check the amount of the shift between the paper edge and the center line of the indicator, enter the corresponding value, and press [OK].
When the center line of the indicator is outside the paper edge (when the center line of the indicator is not printed on the page), set a positive (+) value. The print position moves toward the trailing edge according to the feed direction. Example: If the center line of the indicator on the front side is 0.4 mm outside the edge of the paper, set [Front Side] to "0.4 mm."
When the center line of the indicator is inside the paper edge, set a negative (-) value. The print position moves toward the leading edge according to the feed direction. Example: If the center line of the indicator on the front side is 0.6 mm inside the edge of the paper, set [Front Side] to "-0.6 mm."

If further adjustment is needed, repeat Steps 1 to 3.
* When you display the [Adjust Image Position] screen after performing Adjust Left Edge Alignment or Adjust Lead Edge Alignment, the value on the screen is reset to "0.0 mm," but the previously set value is retained. If you want to repeat the adjustment, check the indicator on the reprinted test page and set that value.
5
Press [OK] [Close].
NOTE
If you want to reset the retained adjustment values to the initial values and perform the adjustment again, press [Restore Initial Settings] on the screen for setting the values.
