To allow sensors to be checked for operation easily and safely, data applied to the IC on the
board can be checked on the panel with the copier in the standby state (including a mis-
feed, malfunction, and closure failure condition).
<Electrical Components Check Procedure Through Input Data Check>

When a paper misfeed occurs in the paper take-up section of the copier, the 2nd Drawer
Paper Take-Up Sensor is considered to be responsible for it.
<Procedure>
1. Remove the sheet of paper misfeed.
2. From the I/O Check List that follows, check the panel display of the 2nd Drawer Paper

→
“I/O Check” and then select the screen that contains “Take-
Up” under “2nd Drawer.” For “Take-Up” under “2nd Drawer,” select “1” on the left-hand
side of the screen.
5. Check that the data for “Take-Up” under “2nd Drawer” is “0” (sensor blocked).
6. Move the actuator to unblock the 2nd Drawer Paper Take-Up Sensor.
7. Check that the data for “Take-Up” under “2nd Drawer” changes from “0” to “1” on the
