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.
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.
When this simulation is executed, the current setup of the code number for each copy mode is displayed. (Default: 0)

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.

(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.
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.
(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.
