Jam detection in the product
The top-of-page sensor (PS801) and the paper-delivery sensor (PS803) detect media moving through
the product. If a jam is detected, the ECU immediately stops the printing process and the Attention
(Cancel) light illuminates on the control panel.
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-paper jam—The top-of-page sensor (PS801) or the paper-delivery sensor (PS803)
detects media in 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.
