4. Duplex adjustment

A. Adjusting the paper reverse position in memory

for duplex copying

This step adjusts the front surface printing (odd-number pages of a doc-

ument set) in the S-D mode copying and the leading edge position of an

image on even-number pages in the D-S mode.

That is, it covers the adjustment of the second surface printing mode

(image loss at the front edge of an image) in which image data is once

stored in memory.

The image data is read, starting from its front end in the document deliv-

ery direction (Reference direction of document setting in the OC

mode)and stored in memory.

This stored image data is printed starting at the printing start position, in

the order of last-stored data to the first-stored data.

In other words, the front edge image loss of the image can be adjusted

by changing the document read end position.

(Adjustment procedure)

1) Preparing test chart (Draw a scale at the rear end of one side of a

sheet of A4 white paper or letter paper).

2) Set the test chart so that the scale is positioned as shown below,

in the S-D mode.

3) Execute simulation 50-18 to make a copy and check the front edge

image loss at the area where the scale is printed.

Adjust the setting so that the front edge image loss is less than 4.0

mm in the Duplex mode.

An increase of 1 in setting represents an increase of 0.1 mm

in image loss.

B. Adjusting trailing edge void in duplex copy mode

This is the adjustment of the first surface printing mode (rear end void)

in duplex copying.

In a duplex copying operation, the paper is delivered starting from the

rear end of the first printing surface. It is therefore necessary to make a

void area at the rear end on the first printing surface to prevent paper

jam at the fusing part.

Adjustment modes:

1) Paper trailing edge void quantity 50-19 (TEXT)

This adjustment is made when the cassette paper size is recog-

nized. The trailing edge void quantity can be adjusted by changing

the trailing edge image laser OFF timing.

(Adjustment procedure)

(1) Paper trailing edge void quantity

1) Preparing test chart (Draw a scale at the rear end of one side of a

sheet of A/4 white paper or letter paper)

2) Set the test chart on the document glass as shown below.

3) Using the user simulation [18], set the paper size of the first cassette.

4) Execute simulation 50-19 to turn on the TEXT lamp and make the

printing mode in OC-D mode.

Make a copy of the test chart to check the void area of the scale on

the image.

Adjust the setting so that the void area is 4 - 5 mm. An increase in 1

of setting represents 0.1 mm in void area.

50 18 Memory reverse position adjustment in duplex copy

When this simulation is executed, the current setup value of correction is displayed. Enter the correction value with the 10-key and

press the PRINT switch, and the entered value will be saved. (Correction value 1 ~ 99, correction zero = 0, or 50) When the correc-

tion value is set to 0, the correction value is written as 50.

Front surface printing in the S-D mode and printing on even pages in the D-S mode are reverse memory copy operations from the

document rear edge section.

When, therefore, the output image print position adjustment is required, adjust as follows:

In the reverse memory copy operation, if the document scan direction is in the direction of the arrow in the figure, the scan rear edge

section of the image is printed first.

When, therefore, the print lead edge is shifted, set the reference chart so that the reference position is in the rear edge section, and

use this simulation to adjust so that the print image lead edge comes to the lead edge.

Since printing is performed by processing the scanned image from the scan end position to the scan lead edge, the print lead edge

position adjustment is performed by changing the end data position stored in memory with the simulation setup value.

19 Duplex copy rear edge void adjustment

Used to adjust the rear edge void quantity in duplex copy.

(Operating procedure)

When this simulation is executed, the current setup value is displayed the current setup value is displayed in two digits. (Center

value: 50 However, setup 50 = setup 0) When the correction value is set to 0, the correction value is written as 50. Press the copy

mode select key to select your desired copy mode, and the display will change. Enter the adjustment value with the 10-key and press

the PRINT switch, and the setup value will be saved and a copy will be made. (The paper information is cleared for every copying.)

Press the clear key to save the setup value and exit from the simulation mode. (Increasing the setup value by 1 increases the void

quantity by about 0.1mm.)
