Detection Timing
The output from AE Sensor Board PWB-H does not
become 4.3V or less for the period between when LA1
turns ON and the Scanner starts a scan motion and when
the Scanner reaches the Image Leading Edge position.
With LA1 OFF, the output from PWB-H remains 4.1V or
less for a continuous 2 second period at any timing while
the Scanner is at the home position or the Original Cover
is lowered.
If a given period of time has elapsed during warming-up,
the surface temperature of the Upper Fusing Roller does
not reach:
• 50°C within 20 seconds;
• 90°C within 20 seconds after it has reached 50°C; or
• 150°C within 20 seconds after it has reached 90°C.
The copier does not complete its warming-up cycle within
15 seconds after the above surface temperature has
reached 150°C.
• The surface temperature of the Upper Fusing Roller
remains less than 135°C for a continuous 1 second or
more period after the copier has warmed up.
• The surface temperature of the Upper Fusing Roller
remains less than 80°C for a continuous 1 second or
more period while in energy saving mode.
The surface temperature of the Upper Fusing Roller
remains 230°C or more after the copier has warmed up.
• When the Scanner is at a position other than home,
Scanner Reference Position Sensor PC81 does not go
from HIGH to LOW after the lapse of 20 seconds after
the Power Switch has been turned ON.
• When the Scanner is at the home position, PC81 does
not go from LOW to HIGH after the lapse of 5 seconds
after the Scanner has started a scan motion.
• PC81 does not go from HIGH to LOW after the lapse of
20 seconds after the Scanner has started a scan
motion.
does not go from HIGH to LOW, or vice versa, after the
lapse of 15 seconds after M6 has started turning.
PC86 does not go from HIGH to LOW after the lapse of
10 seconds after M7 has started turning.
• The output from PC86 does not go from LOW to HIGH
after the lapse of 3 seconds after M7 has started turn-
ing.
The output from PWB-H does not fall within the 2V – 4V
range during the initial F5 mode.
The output from UN3 remains 0.4V or less, or 4.6V or
more, for a continuous 2 second period 2 seconds after
PC Drive Motor M2 has started turning.
