Detection Timing
The system fails in checking initial engine connection
when Power Switch S1 is turned ON.
The system succeeded in checking initial connection
when S1 was turned ON; then it fails in rechecking
initial connection through the execution of a software
reset when a communications error occurs during
operation.

The Lock signal remains HIGH for a continuous 1-sec.
period or more while M2 remains energized.
The Lock signal remains HIGH for a continuous 1-sec.
period or more while M1 remains energized.
<Resolution selection failure detection>
The Lock signal is not detected for a given period of
time after the resolution has been selected. (The Lock
signal is not, however, detected for 1 sec. after the
start.)
<Faulty Lock signal detection>
No Lock signals are detected for the 1 sec. period
which starts 1 sec. after the first Lock.
First Lock: The first Lock signal following 1 sec. after
the selection of start or half speed.
<Out-of-timing Lock detection>
The Lock signal is not detected for a continuous 0.5
sec. period while M10 is in the stabilized turning state
(after a Lock has been detected).
<Abnormal Lock detection>
The Lock signal remains ON for a continuous 5sec.
period while M10 remains deenergized.
The Lock signal remains HIGH or LOW for a continuous
1-sec. period or more while M3 remains energized.
The Lock signal (analog input voltage) remains 0.4V or
less for a continuous 0.5-sec. period or more while M4
remains energized.
The SOS rising edge is not detected even after the
lapse of 0.2 sec. after Polygon Motor M10 has started
and laser output started.
No SOS rising edges are detected while VIA remains
ON.
The temperature of the Fusing Rollers do not reach the
required level even after the lapse of a given period of
time during a warming-up cycle.
From room temperature to 100°C: Within 65 sec.
From 100°C to 140°C: Within 25 sec.
From 140°C to 170°C: Within 20 sec.
From 170°C to the completion of warming-up: Within
22 sec.
The fusing temperature remains 130°C or less for a
continuous 0.1-sec. period or more during the standby
state or printing.
The fusing temperature remains 80°C or less for a
continuous 2-min. period or more during the low-
temperature standby state.
