∗ This setup does not affect black-and-white copies.
(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.

48 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.
In addition, the black level automatic adjustment is performed simultaneously.
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.

Image scan start position
(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.
To perform the automatic adjustment, place the gray gradation chart (UKOG-0162FCZZ) face down so as to fit with the left center of the
platen with the darker side (Density 10) on the left of OC.
