Jam detection

The product uses the following sensors to detect the presence of print-media and to check whether the print-media is being fed correctly or has jammed:

TOP sensor (PS5)

Fuser delivery sensor (PS6)

Loop sensor 1 (PS7)

Loop sensor 2 (PS8)

Output bin media full sensor (PS10)

The product detects the following jams:

Pickup delay jam

Tray 1 (MP tray): The TOP sensor does not detect the leading edge of paper within a

 

specified period, including a retry, after the MP tray pickup solenoid is turned on.

 

Tray 2 cassette: The TOP sensor does not detect the leading edge of paper within a

 

specified period, including a retry, after the Tray 2 cassette pickup solenoid is turned on.

 

Paper feeder: The TOP sensor does not detect the leading edge of paper within a specified

 

period after the paper-feeder (PF) feed sensor detects the leading edge.

 

 

Pickup stationary jam

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

 

leading edge of paper reaches the secondary transfer roller unit.

 

 

Fuser delivery delay jam

The fuser delivery sensor does not detect the leading edge of paper within a specified period

 

after the leading edge of paper reaches the secondary transfer roller unit.
