Document size detection by document set tray
When a document is set on the document set tray in the auto mode of paper/copy magnification ratio selection, the document size is de­tected to perform the auto selection function of paper and the copy magnification ratio according to the detected document size.
When documents of different sizes are mixed and set on the tray, the max. size is detected. The document width is detected by the docu­ment width sensors (W1, W2, W3), and the document length is de­tected by the document length sensors (L1, L2) to determine the document size.
The document size judgment is made after a certain time from when the document set sensor (W0) detects the document.

During execution, "EXEC" is highlighted.
Normal end Abnormal end
Open the SPF unit and press the [OK] key. [ ] indicates the order number of the pixel of the white sheet for SPF exposure correction in the SPF position.
When the adjustment is completed normally, "COMPLETE" is displayed, and data are written into the EEPROM. When the adjustment is completed abnormally, "ERROR" is displayed and data are not written into the EEPROM.
[CA] key: Cancels the test command. [Interruption] key: Shifts to the sub code entry menu. [OK] key: Shifts to the execution menu.
