When the original cover is closed, the original sensor is not read and it is judged as no original at all. (All the original size LED's are turned off.)
Since the machines for Japan/Taiwan are not equipped with the PD0 sensor, the original size LED display is not made.
For the other areas, PD1 and PD3 sensors are not provided and the original size LED display is not made.
02 | Original sensor adjustment |
The original sensor input values of original presence and original empty are read to set the original judgement level.
When this simulation is executed, “1” is displayed on the copy quantity display and the ready lamp lights up. First, in order to read the original sensor input value of original empty, press the PRINT button without an original on the original table with the original cover open. The copy quantity display will change to “2.”
Then, in order to read the original sensor input value of original presence, press the PRINT button with an A3 paper on the original table. The copy quantity display will change to “0.” Then the operation of SIM
After completion of reading the original sensor inputs, the average value of the two inputs is stored as the original judgement level.
03 | Original sensor light reception level and original judgement level display |
Used to display the original sensor light reception level and the original judgement level on the copy quantity display.
Display is selected by the magnification ration selection key.
Since there are two or more display items, the third digit is used to make distinction between the light reception level and the original judgment level, and the lower two digits are used to display the data. The currently set original sensor is displayed by the LED on the original size display section. The relationship between the sensor name and the original size LED is the same as SIM
