Jam detection
The top-of-page sensor (PS801) and the paper-delivery sensor (PS803) detect media moving
through the printer. If a jam is detected, the ECU immediately stops the printing process and the jam
light on the control panel illuminates.
Conditions of jam detection
● Pickup-delay jam—Paper does not reach the top-of-page sensor (PS801) within 1.4 seconds
after the pickup solenoid (SL1) has been turned on, a second pickup operation is attempted,
and paper again does not reach the top-of-page sensor within 1.4 seconds.
● Pickup stationary jam—The top-of-page sensor (PS801) does not detect the trailing edge of
media within 4.6 seconds of detecting the leading edge.
●
Delivery-delay jam—The paper-delivery sensor (PS803) does not detect the leading edge of
media within 2.1 seconds after the top-of-page sensor (PS801) detects the leading edge.
● Wrapping jam—The paper-delivery sensor (PS803) does not detect the trailing edge of the
media within 1.5 seconds after the top-of-page sensor (PS801) detects the leading edge and
within ten seconds after the paper-delivery sensor (PS803) detects the leading edge.
● Delivery-stationary jam—The paper delivery sensor (PS803) does not detect the leading edge
of media within 2.2 seconds after the top-of-page sensor (PS801) detects the trailing edge.
●
Residual media jam—The top-of-page sensor (PS801) or the paper-delivery sensor (PS803)
detects media during the initial rotation period.
● Door-open jam—The top-of-page sensor (PS801) or the paper-delivery sensor (PS803)
detects media while the print cartridge door is open.
