6.3.7 Exit Sensor failure
NOTES:
1. The diagnostic tool is not used in this FIP.
2. If the actuator is the problem, the control panel message may be: Paper Jam>Exit
3. If the exit sensor is disconnected or the paper doesn’t reach the sensor, the control panel
message may be: Paper Jam>Tray.
4. Order the sensor separately, because it is not part of another FRU; the actuator is part of
fuser.
1. INITIAL ANALYSIS
Inspect the following components. Are they compatible with your printer version, correctly
installed, not damaged, deformed, or contaminated?
• Exit Sensor
• MCU PWB
• LVPS Assembly
• Sensor Harness Assembly
Inspect the printer paper path. Is it clear of foreign matter, such as staples, paper clips, and
paper scraps?
Yes No
Go to Step 2. Replace the problem components.
2. LVPS ASSEMBLY ANALYSIS
Disconnect P/J 111 from the HVPS. Perform this test within 30 seconds after switching power on.
After 30 seconds, the LVPS shuts down with a no-load condition.
Is there +5VDC between P 16–1 and 16–2 on the MCU PWB?
Yes No
Go to Step 3. Go to Section 6.3.1
LVPS Assembly Failure (+5VDC).
3. EXIT SENSOR ACTUATOR SIGNAL ANALYSIS
Disconnect P/J 111 from the HVPS. Perform this test within 30 seconds after switching power on.
After 30 seconds, the LVPS shuts down with a no-load condition.
Is there +5VDC between P 16–3 and 16–2 on the MCU PWB?
Yes No
Go to Step 4. Replace the MCU PWB.
