Adjusting the Image Position If the printed image position is misaligned or distorted as in the following cases when using long sheets, you can adjust the printed image position by printing and measuring a long sheet test page (long_sheet_test_chart_duplex_01.pdf) and specifying setting values.

When the printed image is slanted: Perform the Correct Image Misalignment mode. (See "Correct Image Misalignment," on this guide.)

When the printed image is distorted like a parallelogram: Perform the Correct Distortion (Parallelogram) mode. (See "Correct Distortion (Parallelogram)," on this guide.)

When the printed image is distorted like a trapezoid: Perform the Correct Distortion (Trapezoid) mode. (See "Correct Distortion (Trapezoid)," on this guide.)

When the printed image is enlarged or reduced: Adjust the zoom ratio of the image. (See "Adjusting the Zoom Ratio of the Image," on this guide.)

When the printed image is misaligned vertically or horizontally: Adjust the left edge or lead edge alignment. (See "Adjusting Left Edge Alignment of the Image" and "Adjusting Lead Edge Alignment of the Image," on this guide.)

The image positions on the first side and second side may match each other, if you adjust the image position in order shown below. Correct image misalignment → correct distortion (parallelogram) → correct distortion (trapezoid) → adjust the zoom ratio → adjust the left edge alignment → adjust the lead edge alignment.

NOTE · You cannot change the image position on paper which is being used for printing jobs. · To adjust the image position on long sheets, print out a long sheet test page

(long_sheet_test_chart_duplex_01.pdf). The adjustment can be made more efficiently than with the test page printed out by [Output Test Page] under <Adjust Image Position>.

3

Long Sheet Test Page The long sheet test page used when you adjust the image position of long sheets is described below. The following shows the long sheet test page which is printed on user-defined size (330.2 x 762 mm) paper. (The side with "1st side" printed is the front side. The side with nothing printed on it is the back side.)

NOTE · 'b', 'f', 'h', and 'j' may be printed multiple times depending on the size of the output paper. Make the

adjustment at the position nearest to the tail edge of the paper. · The long sheet test page, which you printed for correct distortion (parallelogram), can also be used for

correct distortion (trapezoid), adjust the zoom ratio, adjust the left edge alignment, and adjust the lead edge alignment. If you adjust the image position in the order of correct image misalignment → correct distortion (parallelogram) → correct distortion (trapezoid) → adjust the zoom ratio → adjust the left edge alignment → adjust the lead edge alignment, you need to print a long sheet test page when you make the adjustment shown below.

· Before you start the correct image misalignment. · Before you start the correct distortion (parallelogram).

IMPORTANT · Before making adjustments, clean the platen glass and the back of the feeder. · Before making adjustments, print the long sheet test page (long_sheet_test_chart_duplex_01.pdf) with

the following conditions. If it is not printed properly, the adjustments may not be accurate. · Set the zoom ratio to 100% (same size). · Use the paper to use for the output to print the long sheet test page.

4

Marks for Correct Image Misalignment, Correct Distortion (Parallelogram), and Correct Distortion (Trapezoid) The 'i' and 'j' marks are used for Correct Image Misalignment, 'a' and 'g' marks are used for Correct Distortion (Parallelogram), and 'b' and 'h' marks are used for Correct Distortion (Trapezoid). · If the printed image is misaligned, you can adjust the image position by specifying the Correct

Image Misalignment mode. The image position is corrected after you measure and enter the length of the 'i' mark and the 'j' and 'h' marks that are closest to the tail edge of the paper.

5

· If the printed image is distorted like a parallelogram, you can adjust the angle of the image by specifying the Correct Distortion (Parallelogram) mode. The angle of the image is corrected after you measure and enter the length of the 'a' and 'g' marks.

· If the printed image is distorted like a trapezoid, you can adjust the angle of the image by

specifying the Correct Distortion (Trapezoid) mode. The angle of the image is corrected after you measure and enter the length of the 'b' and 'h' marks that are closest to the tail edge of the paper.

6

Register Marks for Adjusting the Zoom Ratio The zoom ratio of printed area is shown by 'f' and 'd' on the long sheet test page. When the setting is correct, the length of 'f' will be 450.0 mm, 550.0 mm, 650.0 mm and the length of 'd' will be 250 mm.

NOTE If you print the long sheet test page using paper smaller than 10 5/8" x 30" (270 mm x 762 mm), the entire image will not be printed on the paper. Calculate the expanding/reducing percentage by comparing the measured length of 'd/2' with the default value (d/2: 125 mm). If 'f' is not printed entirely, measure the length of 'f' that is closest to the tail edge of the paper, and calculate the expanding/reducing percentage by comparing the measured length with the default values (f=450 mm, 550 mm, 650 mm). By using the calculated percentage, adjust the zoom ratio. (See "Adjusting the Zoom Ratio of the Image," on this guide.)

Adjusting the Zoom Ratio of the Image 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 to adjust the zoom ratio for the back side to be the same as the enlarge/reduce ratio for the front side. You can adjust the zoom ratio of the image either by entering the enlargement/reduction ratio, or by entering the value of the long sheet test page you measured manually.

NOTE Before adjusting the zoom ratio, output the long sheet test page using paper for printing.






6 Return to the <Adjust Image Position> screen → set the zoom ratio. If you enter the enlargement/reduction ratio (%):

Set the enlargement/reduction ratio (%) for <Zoom (f)> and <Zoom (d)> on <Adjust Image Position> screen → press [OK].

<Zoom (f)>: Enlarges or reduces the image in the direction that is parallel to the feeding direction

according to the inputted ratio. <Zoom (d)>: Enlarges or reduces the image in the direction that is perpendicular to the feeding

direction according to the inputted ratio. As necessary, try printing the long sheet test page again and then check the correction amount.

23

If you enter the value of the long sheet test page you measured manually: □ Measure the length of the 'f' and 'd' marks on the long sheet test page manually.

Default value: f = 450.0 mm, 550 mm, 650 mm, d = 250.0 mm

NOTE If you print the long sheet test page using paper smaller than 10 5/8" x 30" (270 mm x 762 mm), the entire image will not be printed on the paper. Calculate the expanding/reducing percentage by comparing the measured length of 'd/2' with the default value (d/2: 125 mm). If 'f' is not printed entirely, measure the length of 'f' that is closest to the tail edge of the paper, and calculate the expanding/reducing percentage by comparing the measured length with the default values (f=450 mm, 550 mm, 650 mm). By using the calculated percentage, adjust the zoom ratio. (See "Adjusting the Zoom Ratio of the Image" on this guide.)

□ Press [Adjust Using Test Page].

24

□ Enter the length of the long sheet test page on both front and back sides → press [OK]. For example, if the input value of [f] is 360.4 mm, enter 360.4. The difference in length (0.4 mm in this case), is reduced, so that the image is printed in the correct size.

[f]: Enter the input value calculated from the measured length of 'f' mark on the long sheet test

page. Input value = ((default ‘f’ value: 360 mm)/measured ‘f’ position: 450, 550, 650 mm)) x

measured ‘f’ value [d]: Enter the measured length of 'd' mark on the long sheet test page. As necessary, try printing the long sheet test page again and then check the correction amount.

7 Press [OK].

25

Adjusting Left Edge Alignment of the Image In the feeding direction, if the image position on the output paper is moved left and right from the correct position, the misaligned image position may be corrected by adjusting the margin on the left edge of the paper.






26

If you enter the difference from the measured length of the long sheet test page:

NOTE Before adjusting left edge alignment of the image, output the long sheet test page using paper for printing.

□ Return to the <Adjust Image Position> screen and measure the length of 'i' for both front and back sides of the printed long sheet test page.

Default value: 'i' = 20.0 mm

27

□ Enter the difference in length between the measured value of 'i' and the default value (20 mm) for both front and back sides.

For example, if the measured length of 'i' is 21.5 mm, enter - 1.5 mm for <Left Edge (i) Align.>. For example, if the measured length of 'i' is 18.5 mm, enter + 1.5 mm for <Left Edge (i) Align.>. The difference of 1.5 mm between the measured length and the default value is corrected.

□ Press [OK]. As necessary, try printing the long sheet test page again and then check the correction amount.



* Feeding Direction

28

□ Measure the length of 'i', which is the distance from the left edge of the printed area to the left edge of the paper, and enter the difference from the default value (20 mm).

For example, if the measured length of 'i' is 21.0 mm, enter - 1.0 mm for <Left Edge (i) Align.>. For example, if the measured length of 'i' is 19.0 mm, enter + 1.0 mm for <Left Edge (i) Align.>. The 1.0 mm difference between the measured value and the default value is corrected.


6 Press [OK].

IMPORTANT When you open the screen again after you close the screen by pressing [OK], the values on screen are returned to '0'. However, the adjusted value is still effective in each Total field. If you repeat the step, check the length of 'i' on the new long sheet test page and enter the new value.

When a Paper Jam Occurs with Long Sheets If a paper jam occurs, a screen with a list indicating the order to clear the jam appears on the touch panel display. Check the location of the paper jam, and follow the instructions on the screen and this manual to clear the paper jam. The screen is displayed repeatedly until the paper jam is cleared. If you press [Close], you can continue operations, such as setting modes or scanning originals, even if the jammed paper is not removed immediately.

CAUTION · When removing jammed paper, take care not to cut your hands with the edge of paper. If you cannot

remove the paper from the machine, contact your local service representative. · When removing paper which has become jammed inside the machine, take care not to allow the toner on

the jammed paper to come into contact with your hands or clothing. If they become dirty, wash them immediately with cold water. Washing them with warm water will set the toner, and make it impossible to remove the toner stains.

· When removing paper which has become jammed inside the machine, remove the jammed paper gently to prevent the toner on the paper from scattering. The toner may get into your eyes or mouth. If the toner gets into your eyes or mouth, wash them immediately with cold water and immediately consult a physician.

· The fixing unit and its surroundings inside the machine may become hot during use. When removing jammed paper or when inspecting the inside of the machine, do not touch the fixing unit and its surroundings. Doing so may result in burns.

· The lifter inside the paper decks rises and descends automatically. When clearing paper jams inside the paper decks, be careful not to get your fingers caught.

· After clearing all paper jams, remove your hands from the machine immediately. Failure to do so may result in getting your hands or clothing caught in the feed rollers, which could result in personal injury.

IMPORTANT · Some areas that are shown to have paper jams may not actually have paper jams. However, always

check all locations indicated on the screen in the order that is given. · Unless explicitly specified in the instructions, do not pull out any unit before clearing the paper jam. Doing

so may cause the paper to tear and leave pieces of paper inside the machine.

33
