Scan-Graphics CF Series Maintenance Manual page 61

If you enter <7>, messages will come up showing which sensors are on (detecting something in
their path). The sensors are identified as: A (before first roller) ; B (between first roller and
scan window) ; and C (right after scan window). When this test is selected, a message similar
to the one shown in figure 5-27 will appear.
To check that the sensors are operating, load a document and monitor the display. The display
shows which sensors detect the document and dynamically changes with detection.
Choice <X> returns to the Diagnostic Tests menu.
