Delivery sensors
Delivery delay jam
A delivery delay jam is assessed if the media does not reach the delivery sensor (PS2301) within
a specified period of time (T) after the top-of-page sensor (PS2305) detects the leading edge.
● paper 270 mm or longer: T = approximately 2.6 seconds
● paper 200 mm to 270 mm: T = approximately 2.7 seconds
● paper shorter than 200 mm: T = approximately 4.6 seconds
Delivery stationary jam
A. When the WAIT period starts—a delivery stationary jam is assessed if the delivery sensor
(PS2301) detects media when the WAIT period starts.
B. During media feeding—a delivery stationary jam is assessed if the delivery sensor (PS2301)
does not detect the trailing edge of the media within a specified period of time (T) after the
top-of-page sensor (PS2305) detects the trailing edge.
● paper 200 mm or longer: T = approximately 2.7 seconds
● paper shorter than 200 mm: T = approximately 5.2 seconds
C. When a pickup delay jam occurs—the printer enters the last rotation period to deliver the
jammed media. A delivery stationary jam is assessed if the delivery sensor (PS2301) does
not detect the trailing edge of the media within 8 seconds after the completion of the forced
laser emission.
D. During pressure-roller cleaning—a delivery stationary jam is assessed if the delivery sensor
(PS2301) does not detect the trailing edge of the media within 8 seconds after the 35th feed
operation.
Reversing sensors
Reversing delay jam
A reversing delay jam is assessed if the reversed paper sensor (PS501) does not detect the
leading edge of the media within 3.9 seconds after the reversing motor starts rotating.
Reversing stationary jam
A reversing stationary jam is assessed when the reversed paper sensor (PS501) detects media
after automatic duplexer pickup operation has been performed for about 0.77 seconds.
