γ table setup or AE operation mode setup
When this simulation is executed, the current setup of the gamma table code number is displayed. (Default: Japan = 1, EX Japan = 2) 
Enter the code number corresponding to desired gamma table, and press the PRINT switch or the copy mode select key to enable the 
setup.
When the copy mode select key is pressed during setup of the gamma table, the mode is switched to the AE operation setup mode and 
the current setup of the AE operation mode code number is displayed. (Default: 0) Enter the code number corresponding to your 
desired AE operation mode, and press the PRINT switch or the copy mode select key to switch the setup. (When the copy mode select 
key is pressed, the mode is returned to the gamma table setup mode.)

SPF exposure correction
Used to adjust the exposure correction quantity in the SPF mode by adjusting the differential of Vref voltage for the OC mode.
(Operating procedure)
When this simulation is executed, the current setup is displayed. Enter the adjustment value with the 10-key and press the PRINT key 
to enable the setup and make a copy.
When the CLEAR key is pressed, the entered value is saved and the simulation mode is terminated.
∗ The greater the value is the darker the exposure is.
The smaller the value is, the brighter the exposure is.
29
Image contrast adjustment (600dpi)
Used to set the contrast in each mode.
(Operation/Procedure)
When this simulation is executed, the machine performs warm-up and shading, and the current setup value is displayed in two digits. 
(Default: 50)
Use the copy quantity keys to change the setup value, and press the PRINT switch to make a copy with the new setup.
The greater the setup value is, the greater the contrast is, and vise versa. Only EXP.3 copy is made, however, EXP.1 contrast and 
EXP.5 contrast are also changed accordingly.
When the CLEAR key is pressed, the entered setup value is saved and the simulation is terminated.
Any copy mode can be selected with the copy mode select key. The setup value of the selected copy mode is displayed on the copy 
quantity display.
(Setup range: 0 – 99)

Image sharpness adjustment
Used to adjust the clear/shading-off of an image in each mode.
(Operating procedure)
When this simulation is executed, warm-up and shading operations are performed and the current setup value is displayed. (Default: 1)
Change the setup value with the copy quantity keys. Press the PRINT switch and a copy is made according to the new setup. When the 
clear key is pressed, the entered setup value is saved and the simulation is terminated.
Any desired copy mode can be selected with the copy mode select key. The code number of the selected copy mode is displayed on

Copier color reproduction setup
Used to set color reproduction for each mode. Colors which are easily copied or which are not easily copied are selected.
(Operating procedure)
When this simulation is executed, the current setup of the code number for each copy mode is displayed. (Default: 0)
Change the setup value with the copy quantity keys and press the Print switch. A copy will be made according to the setup. At that time, 
the color component used for copying is changed.
When the clear key is pressed, the entered code number is saved and the simulation mode is terminated.
Any desired copy mode can be selected with the copy mode select key. The selected copy mode is displayed on the copy quantity 
display.

01
Front/rear (main scanning) direction and scan (sub scanning) direction magnification ratio adjustment
(1) Front/rear direction magnification ratio auto correction: The width of the reference line marked on the shading correction plate is 
scanned to perform automatic correction of the front/rear (main scanning) direction magnification ratio as well as automatic setup of 
the OC/document center offset value and of the image scan start position.
The OC/document center offset value and the image scan start position automatically set in this simulation, can be checked by the 
respective manual setup simulation for each adjustment shown below.
(2) Front/rear direction magnification ratio manual correction: By key operations, the front/rear (main scanning) direction magnification 
ratio is set by changing the setup value of the ZOOM DATA register to AISC.
(3) Scan direction magnification ratio correction: The scan direction magnification ratio in the OC mode is set by changing the scan 
speed.
(4) SPF mode scan direction magnification ratio correction: The SPF mode scan direction magnification ratio is set by changing the 
scan speed.
(Operating procedure)
When this simulation is executed, the current setup value is displayed in two digits. (Center value: 50) Press the copy mode select key 
to select each setup mode and the setup display will change accordingly.  In the case of the front/rear direction automatic adjustment, 
when the PRINT switch is pressed, the mirror base unit moves to the shading white board, and the width of the reference line is 
scanned, and the correction value is calculated, and the value is saved.
For manual adjustment, enter the adjustment value with the 10-key and press the PRINT switch, the set value will be saved and a copy 
will be made. When the clear key is pressed, the value entered will be saved and the simulation will be terminated. (Increasing the 
setup value by 1 increases 0.1%.)
In the front/rear direction magnification ratio automatic correction
(1) When the calculated value of the scan correction value is within ±5%, “– –” is displayed.
(Cause) Erroneous position of the reference line on the white board, improper installation of the lens unit, etc.
(2) In case of a scan error of the reference line, the jam lamp lights up.
(Cause) CCD error, no white board installed.
∗ If the automatic correction of the magnification ratio cannot provide a satisfactory result, use the manual correction.

Flash ROM program writing mode
(Operating procedure)
When this simulation is executed, “d” is displayed on the display and the machine enters the Flash ROM program writing mode.
Use the writing tool to write the program from PC. During writing, the display indicates as shown below. After completion of 
downloading, turn OFF/ON the power to reset.

Lead edge image position
Used to adjust the copy image position and the lead edge void quantity on the copy paper. The adjustment is made by adjusting the 
image scan start position and the print start position (resist roller ON timing) at 100%.
(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) Press the copy mode select key to select your desired coy 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. Press the clear key to save the setup 
value and exit from the  simulation mode. When the adjustment is made for the main cassette feed, all the adjustment values at all the 
paper feed ports become the same. (Increasing the setup value by 1 corresponds to about 0.1mm shift.)
(Adjustment procedure)
1. Set the print start position (A), the lead edge void quantity (B) and the scan start position (C) to 0, and make a copy at 100%.
2. Measure the image loss quantity (R mm) of the scale.
Set C = 10 
× R (mm) (Example: Set 40.)
When the value C is increased by 10, the image loss is decreased by 1mm. 
(Default: 50)
3. Measure the distance (H mm) from the paper lead edge to the image print 
start position.
Set A = 10 
× H (mm)   (Example: set 50)
When the value A is increased by 1mm, the image lead edge is shifted to 
the paper lead edge by 1mm. (Default: 50)
4. Set the lead edge void quantity to B = 50 (2.5mm). (Default: 50)
When the value B is increased by 10, the void is increased by about 1mm.
(When set to 25 or less, the void becomes zero.)
∗ The SPF adjustment is performed by adjusting the SPF image scan start position.
