Detection Timing
<Faulty start detection>
• The Lock signal is not detected at any time during a
given period of time 1 sec. after the Polygon Motor
has been energized.
<Faulty Lock signal detection>
• No Lock signals are detected at any time during the
1-sec. period which starts 1 sec. after the first Lock.
<Out-of-timing Lock detection>
• The Lock signal is not detected for a continuous 0.5-
sec. period while the Polygon Motor is in the stabi-
lized turning state.
<Abnormal Lock detection>
• The Lock signal remains ON for a continuous 5-sec.
period while the Polygon Motor remains deener-
gized.
Communications with the gate array for expansion I/O
(the IC mounted on the Master Board) fail.
The connection status of a finishing option is changed
after the power has been turned ON.
After failing to blow the imaging cartridge fuse two
consecutive times, the I/C is determined to be new.
EEPROM, in which no initial data is written, is found.
more after the Polygon Motor has been energized
and laser output started.
• No SOS falling edges are detected while VIA
remains ON.
