No Paper Sensing
A No-Paper Sensor detects when the Paper Tray is empty. When the last sheet is fed from the
tray, the No-Paper Sensor actuator drops into a hole within the Tray Level Lift. The actuator
blocks the sensor and the sensor's output switches to high.
This level is sent to the IOT Drive and Control PWBAs, which deactivates the tray's Feed Motor.
In addition, these PWBAs cause a message to appear on the User Interface display. send a
status message to the User Interface Base PWBA.
No Paper Sensor. This circuitry is the same for Trays 1 through 4.

Figure 1
shows the circuitry relating to the
Tray 5
Tray 5 is used mainly to feed transparencies, thick paper, and envelopes. It can also be used to
feed small quantities of paper not in Paper Trays 1 through 4. Tray 5 has a maximum capacity
of 1-100 copies.
When material is placed in Tray 5, it pushes against an actuator finger of the Tray 5 Paper Sen-
sor, causing it to change level. The switch output is routed to the IOT Drive and Control
PWBAs.
