The Toner Sensor is actuated while warming up.
Step
1
Inspect the following components.
• CRU (PL8.1.1)
• Toner Sensor (PL5.1.1)
• Harness Assy Toner Sensor (J42-J421) (PL5.1.32)
• Harness Assy Conn (J23-J231) (PL10.1.10)
• PWBA Conn (PL10.1.11)
• PWBA HKB26 MCU (PL10.1.13)
Are they compatible with your printer version, correctly
installed, not damaged, deformed, or contaminated?
2
Replace the CRU with new one.
Does the J5 error still appear?

HARNESS ASSY TONER SENSOR (J42-J421) (PL5.1.32)
ANALYSIS
Check the continuity between J42-1 <=> J421-4, J42-3 <=>
J421-2, and J42-4 <=> J421-1.
Is there the continuity between J42-1 <=> J421-4, J42-3
<=> J421-2, and J42-4 <=> J421-1?

PWBA CONN (PL10.1.11) ANALYSIS
1. Disconnect J42 and J231 from the PWBA Conn.
2. Check the continuity between P42-4 <=> P231-9, P42-3
<=> P231-11, and P42-1 <=> P231-11.
Is there the continuity between P42-4 <=> P231-9, P42-3
<=> P231-11, and P42-1 <=> P231-11?
5
Harness Assy Conn (J23-J231) (PL10.1.10) ANALYSIS
1. Disconnect J231 from the PWBA Conn and J23 from the
PWBA HKB26 MCU.
2. Check the continuity between J23-8 <=> J231-9, J23-6 <=>
J231-11, and J23-5 <=> J231-12.
Is there the continuity between J23-8 <=> J231-9, J23-6
