When the main code is inputted, the LCD shows the following
display and a sub code blinks on the copy quantity display.
With the RPL on, enter the desired sub code and press the
START key to start the operation.
SIMULATION NO.1
INPUT 1 ~ 5
1. OPTICAL SYSTEM SCAN.
2. OPTICAL SYSTEM SENSOR TEST.
3. LENS TEST,
4. LENS AGING TEST.
5. LENS LOCK POSITION SETTING.
When the sub code is entered, the RPL lights up to allow
setting of the magnification ratio with the magnification ratio
key. Set the magnification ratio and press the START key, and
the mirror base and No.4/5 mirror/lens home positions will be
sensed and mirror scanning will be performed at the set ratio.
When the sub code is entered, the LCD shows the following
display to allow checking of the optical system sensors. (The
display is highlighted when sensed.)

When the sub code is entered, the mirror base, No. 4/5 mirror,
and the lens home positions are sensed and No. 4/5 mirror
moves one cycle of fixed magnification ratios.
(One cycle of fixed magnification ratios)
100% → 50 % → 70% → 81% → 86% → 200% → 141%
→ 122% → 115% → 100%
When the sub code is entered, simulation 1-3 is repeated.
When the sub code is entered, the lens and No. 4/5 mirror are
moved to the fixing screw position. (Used to move the copier
body.)
When the main code is inputted, the LCD shows the following
display and a sub code blinks on the copy quantity display.
With the RPL on, enter the desired sub code and press the
START key to start the operation.
SIMULATION NO. 2
INPUT 1~3
1. RADF AGING TEST.
2. RADF SENSOR TEST.
3. RADF COMPONENT OPERATION TEST.
