4) Without paper on the original tray, press
the push switch (SW3) on the DADF

LED2 of the DADF controller PCB
have tuned on and the voltage of TP1-1
is 1.1 ±0.1 V and that of TP1-2 is 4.1
±0.2 V.
If the voltage of either check pins is not
as indicated, the light-emitting segment
and the light-receiving segment of the
sensor in question are likely to be mis-
aligned. Check the position of that sen-
sor.
