Jam Sensors and Jam LEDs

When a jam (including a jam detected during initialization) occurs, a jam sensor detects it, and then
the corresponding LED blinks.

Jam LEDs blink when the front door is open in a jam condition.

When multiple LEDs blink to indicate jam locations, they blink at the same time.

Jam sensors always monitor even when you are handling a jam (because the sheet following a
jammed sheet moves when you rotate a jam removal knob).

The LED stops blinking two seconds after a jam sensor switches from on to off. If the sensor turns
on again within the two seconds, the LED keeps blinking.

All of the LEDs turn off when the front door is closed. But if a jam is detected during initialization, a
jam LED blinks when the front door opens.
