50 12 Document off-center adjustment
The document scan off-center adjustment is performed.
The adjustment mode is changed over with the copy mode select key. (Adjustment range: 1 – 99, Default: 50)
When the adjustment value is increased, the print result is shifted to the left.

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.
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.)

51 02 Resist quantity adjustment
Used to adjust the contact pressure of paper against the machine resist roller and the RSPF resist roller.
(Operating procedure)
When this simulation is executed, the current setup value is displayed.
Enter the adjustment value with the 10-key and press the PRINT switch, the entered set value will be saved and a copy will be
made. When the clear key is pressed, the entered value will be saved and the machine will exit from the simulation mode.
