Table 1-17Jams that the product detects (continued)

Jam

Description

 

 

Fuser delivery delay jam

The fuser delivery paper-feed sensor does not detect the leading edge of the paper within a

 

specified period after the TOP sensor detects the leading edge.

 

 

Fuser delivery stationary jam

The fuser delivery paper-feed sensor does not detect the trailing edge of the paper within a

 

specified period after it detects the leading edge.

 

 

Wrapping jam

After detecting the leading edge of the paper, the fuser delivery paper-feed 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 paper-feed sensor

 

●

TOP senosor

 

●

Loop sensor 1

 

●

Loop sensor 2

 

 

Door open jam

A door is open while paper is moving through the product.

 

 

Duplexing re-pickup jam 1

The duplex re-pickup sensor does not detect the leading edge of the paper within a specified

 

period after the media reverse operation starts in the duplex reverse unit.

 

 

Duplexing re-pickup jam 2

The TOP sensor does not detect the leading edge of the paper within a specified period after

 

the paper is re-picked.

 

 

 

After a jam, some sheets of paper might remain inside the product. If the DC controller detects residual paper after a door closes or after the product is turned on, the product automatically clears itself of those residual sheets.
