Detection Timing
∗See the option service manual.
Detection Timing
• The LA1 Malfunction signal remains LOW for a contin-
uous 1-sec. period while LA1 remains OFF.
• The LA1 Malfunction signal remains HIGH for a con-
tinuous 1-sec. period while LA1 remains ON.
Detection Timing
The UN6 output voltage does not fall within the range of
0.9V to 1.1V even after the contamination correction and
variation adjustment.
• The UN4 output voltage remains 0.2V or less, or 4.5V
or more, for a continuous 3-sec. period after Develop-
ing Unit Drive Motor M1 has been energized.
• The UN4 output voltage does not fall within the range
of 2.45V to 2.55V during an F8 operation.
A T/C of 2.5% or less (ATDC Sensor output being 3.2V
or more) is detected.
A toner replenishing sequence does not bring T/C to a
normal level within 3 min. after a T/C of 3% or less
(ATDC Sensor output being 2.86V or more) has been
detected.
