Detection Timing
In F7 mode:
• The Busy signal does not go LOW within approx.
0.8 sec. after the initial signal has gone LOW, or
undefined data is input to the Master CPU.
• The Busy signal does not go HIGH within approx. 5
sec. after the initial signal has gone LOW.
• Under normal conditions:
The fixed-cycle pulse signal (Busy) remains HIGH or
LOW for 3 seconds or more.
• Undefined data is input to the Master CPU.
When the Power Switch is ON:
• The Busy signal remains HIGH or LOW for 5 sec-
onds or more.
• Undefined data is input to the Master CPU.
Under normal conditions:
• The output from PWB-H remains less than approx.
0.18V for a continuous 2-second period, with the
Exposure Lamp OFF, the Scanner at the home
position, and the Original Cover lowered.
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%.
F5 or FF for every 100 copies made:
• The output from PWB-H does not fall within the tar-
get range (1.8 ± 0.05V) during adjustment proce-
dures by image stabilization control.
In the initial F5 or FF mode, or F5 or FF for every 100
copies made:
• The output from PWB-G is 1V or more when the
load resistance is made maximum by the 4-bit ana-
log switch.
• The output from PWB-G is less than 1V when the
load resistance is made minimum by the 4-bit ana-
log switch.
• The output from PWB-G does not fall within the
0.9V-1.1V range when the intensity of PWB-G's
LED is varied.
In the initial F5 or FF mode, or F5 or FF for every 100
copies made:
1. The grid voltage (VG) of 550V is output.
2. A solid black pattern is produced and the PWB-G
output is sampled.
3. The average of the above readings is 1.0V or less.
