Short the main PWB pins (JP208-JP206), turn on the power, and "0" will be displayed.
Press the PRINT key, and the total counter content is displayed on the copy quantity display
from the digit of ten thousands to the digit of one in sequence. (This is repeated until the end of
the simulation.)
To terminate total counter read, press the EXPOSURE key, and the mode is changed to the
standby mode for the next simulation (1, 2, or 3).
To terminate the simulation, release the short of the PWB, and turn off and then on the power.
Short the main PWB pins (JP208-JP206), turn on the power, and "0" will be displayed. Then
press the copy quantity set key to display "1."
Press the PRINT key, and the Drum counter content is displayed on the copy quantity display
from the digit of ten thousands to the digit of one in sequence. (This is repeated until the end of
the simulation.)
To terminate drum counter read, press the EXPOSURE key, and the mode is changed to the
standby mode for the next simulation (2, 3, or 0).
To terminate the simulation, release the short of the PWB, and turn off and then on the power.
Short the main PWB pins (JP208-JP206), turn on the power, and "0" will be displayed. Then
press the copy quantity set key to display "2."
