Details of operation
Used to start warmup and count and display the warmup time every
second. After completion of warmup, count up is terminated and the
ready lamp is lighted. When the clear key is pressed and the copy
quantity is entered and the start key is pressed, copying is made to make
the set quantity of copies. At that time, the paper size does not matter.
Key operation
Copy quantity setting: Copy quantity key
Used to bring the machine to the ready state without warmup.
After completion of warmup, counting is stopped and the ready lamp is
lighted. When the copy quantity is entered and the start key is pressed,
copying is made to make the set quantity of copies. After 3 sec standby,
