AR-122E/152E/153E/157E SIMULATION, TROUBLE CODES 10 - 15

Center offset adjustment
Used to adjust the copy image position on the copy paper and the center offset position when scanning a document.
(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, and the entered value will be saved and a copy will be made. When the clear key is pressed, the entered value will be saved
and the simulation will be terminated. (When the setup value is increased by 1, shift is increased by 0.1mm.)

∗

When the setup value is too great, outside of the shading area may be read, and black streaks may be produced on the edges.
When the adjustment value is increased, the image is shifted to the left.
When the adjustment value is decreased, the image is shifted to the right.

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 correction
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.

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.)
