7.3.3 Detecting the Size of Paper
0006-4084
The machine detects the size of paper in the cassette in any of two ways: LGL size detection and non-LGL size
detection.
LGL detection is performed by means of a LGL paper sensor (PS101). The LGL size detection mechanism is used
to prevent picking up a subsequent sheet of paper before the trailing edge of paper leaves the cassette, otherwise
occurring if the pickup was let to occur at the same time using other sizes when picking up LGL paper.
Non-LGL detection is performed using the paper leading edge sensor (PS102) based on the length of paper. In fax
mode, if paper of a size different from the size selected from the control panel is placed, the DC controller will
identify a paper size mismatch at the end of printing and indicate a message on the LCD.
