2.6 Detecting Jams

2.6.1 Outline

The side paper deck is equipped with the following 2 sensors used to find out whether or not paper is moving
smoothly. The machine checks for the presence of a jam at such times as initiated its DC controller PCB and with
reference to the signals from these sensors. When the machine's DC controller PCB identifies a jam, it discharges
sheets ahead of the jam and stops the ongoing operation, after which it will indicate jam removal instructions on its
control panel.
The DC controller of the hostmachine identifies a jam under the following conditions:
1. when the machine's power switch is turned on or at the end of the wait-up period or during standby, the presence
of paper is detected over the deck feed sensor (PS106).
2. deck pickup/vertical path delay jam
When the deck pickup sensor (PS106)/the deck feed sensor (PS101) does not detect paper at the timing of jam check
after starting pickup.
