Table 1-16Jams that the product detects

Jam	Description
Pickup delay jam	The TOP sensor does not detect the leading edge of the paper within a
	specified time (including two retries) after the pickup operation from the
	cassette, multipurpose tray, or optional paper feeder starts.
Pickup stationary jam	The TOP sensor does not detect the trailing edge of the paper within a
	specified time from when it detects the leading edge.
Fuser delivery delay	The fuser delivery sensor does not detect the leading edge of the paper
jam	within a specified period after the TOP sensor detects the leading edge.
Fuser delivery	The fuser delivery sensor does not detect the trailing edge of the paper
stationary jam	within a specified period after it detects the leading edge.
Wrapping jam	After detecting the leading edge of the paper, the fuser delivery sensor
	detects the absence of paper, and it has not yet detected the trailing edge.
Residual paper jam	One of the following sensors detects paper presence during the initialization
	sequence:
	●	Fuser delivery sensor
	●	Loop sensor 1
	●	Loop sensor 2
	One of the following sensors detects paper presence during the an
	automatic delivery operation:
	●	Fuser delivery sensor
	●	TOP sensor
	●	Loop sensor 1
	●	Loop sensor 2
	●	Duplex re-pickup sensor
Door open jam	A door is open while paper is moving through the product.
Duplexing re-pickup	The duplex re-pickup sensor does not detect the leading edge of the paper
jam 1	within a specified period after the media reverse operation starts in the
	duplex reverse unit.
Duplexing re-pickup	The TOP sensor does not detect the leading edge of the paper within a
jam 2	specified period after the paper is re-picked.

Automatic delivery: The product automatically clears paper if the TOP sensor detects residual paper during initialization.
