Detection Timing
The fusing temperature remains 230°C or more for a
continuous 0.1-sec. period or more.
No initial data is written in EEPROM.
After failing to blow the imaging cartridge fuse 2
consecutive times, 3.6V or more is detected and the I/C
is determined to be new.
The HMOT Lock signal is not input for a given period of
time.
The overcurrent detection circuit detects an overcurrent
condition that lasts for a given period of time while EMOT
remains energized.
Lift-Up Sensor 1 LS1 is not blocked (H) within a given
period of time after EMOT has been energized (Lift 1 has
started moving up).
Lift-Up Sensor 2 LS2 is not blocked (H) within a given
period of time after EMOT has been energized (Lift 2 has
started moving up).
LCC becomes uncontrollable due to an error in
communications between the LCC and copier.
The value of data read by E1 is faulty. [E1 reading is 7%
or less (3.92V or more) or 19% or more (1.41V or less).]
In an F8 (ATDC control voltage automatic adjustment)
operation, the adjustment of ATDC control voltage is
not completed within 1 min. after E1 sampling.
In an F8 operation, the control voltage falls outside the
range of 5.39V to 8.15V.
The Lock signal remains HIGH or LOW for a continuous
1-sec. period or more while M8 remains energized.
Toner Bottle Home Position Sensor PC10 remains
blocked (L) for a continuous 2-sec. period or more
while M6 remains energized.
PC10 remains unblocked (H) for a continuous 6-sec.
period or more while M6 remains energized.
(When moving from home to shift position) The Shift
Home Sensor is blocked after a given period of time after
the Shift Motor has been energized (at which timing the
motor is deenergized).
(When moving from shift to home position) The Shift
Home Sensor is not blocked even after the lapse of a
given period of time after the Shift Motor has been
energized.
