Detection Timing
D When the Scanner is at a position other than
home, Scanner Reference Position Sensor
PC81 does not go from HIGH to LOW even after
the lapse of 20 sec. after the Power Switch has
been turned ON.
D When the Scanner is at the home position, PC81
does not go from LOW to HIGH even after the
lapse of 5 sec. after the Scanner has started a
scan motion.
D PC81 does not go from HIGH to LOW even after
the lapse of 20 sec. after the Scanner has started
a scan motion.
The output from Lens Reference Position Sensor
PC90 does not go from HIGH to LOW, or vice
versa, even after the lapse of 15 sec. after M6
has started turning.
D The output from Mirror Reference Position Sen-
sor PC86 does not go from HIGH to LOW even
after the lapse of 10 sec. after M7 has started
turning.
D The output from PC86 does not go from LOW to
HIGH even after the lapse of 3 sec. after M7 has
started turning.
D When the Scanner is at a position other than
home, the SHOME signal does not go HIGH
even after the lapse of 7 sec. after the SCAN sig-
nal has gone LOW.
D The SHOME signal is HIGH even after the lapse
of 5 sec. after the BASE signal has gone from
LOW to HIGH.
The SHOME signal remains LOW even after the
lapse of 7 sec. after it has gone LOW.
The BASE signal does not go LOW even after
the lapse of 5 sec. after the SHOME signal has
gone HIGH.
The BASE signal remains LOW even after the
lapse of 5 sec. after the SHOME signal has gone
HIGH.
The TRON signal remains HIGH even after the
lapse of 5 sec. after the BASE signal has gone
LOW.
The TRON signal remains LOW even after the
lapse of 5 sec. after it has gone LOW.
The SCEND signal remains HIGH even after the
lapse of 5 sec. after the TRON signal has gone
LOW.
The SCEND signal remains LOW even after the
lapse of 5 sec. after it has gone LOW.
