Jam detection in the device
The top-of-page sensor (PS801) and the paper-delivery sensor (PS803) detect media moving through
the device. 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.
