<In normal conditions>
•
The output from PWB-H remains approx. 0.18V or
less for a continuous 2-second period when LA1 is
OFF, PC1 output is LOW, or S7 output is LOW (i.e.
the Original Cover is closed).
<In F5 mode>
•
The output from PWB-H is less than 1.8V when the
gain of the AE Sensor is 100%.
•
The output from PWB-H is 1.8V or more when the
gain of the AE Sensor is 0%.
•
The output from PWB-H is outside the target range
(1.8 ±0.05V) when the gain of the AE Sensor is 50%.
<When the optimum LA1 voltage is changed after the
intensity of LA1 light has been corrected>
•
The output from PWB-H at the AE Sensor gain of
100% is smaller than that for halftones stored in the
F5 mode.
•
The output from PWB-H at the AE Sensor gain of 0%
is smaller than that for halftones stored in the F5
mode.
•
The output from PWB-H at the AE Sensor gain of 50%
is outside the range of (output for halftones stored in
the F5 mode) ±0.05V.
•
The UN9 output is 0.9V or more when all signals from
the 4-bit analog switch are turned LOW (i.e. when a
load resistance is maximum).
•
The UN9 output is less than 1.1V when all signals
from the 4-bit analog switch are turned HIGH (i.e.
when a load resistance is minimum).
•
The UN9 output does not exceed or fall from 1V when
the intensity of the Sensor LED is minimum (after the
variation correction of UN9)
•
The UN9 output is 2V or more when the intensity of
the LED is optimum.
