Error Messages and Codes
4 1.Perform the CRU Sensor test:
Service Mode > Printer Diag >
Engine Diag > Sensor Test > CRU
Sensor.
■ Yellow CRU Sensor (page 4-45)
■ Magenta CRU Sensor (page 4-46)
■ Black CRU Sensor (page 4-47)
■ Cyan CRU Sensor (page 4-48)
2.Does the number on the Control
Panel increase by 1 when the Print
Cartridge is reseated?
Replace the
MCU Board
(page 8-88).
Go to step 5.
5 1.Check the Toner Sensor wiring
harness connectors between the
Print Cartridge Sensor and the MCU
Board.
■ Yellow: P/J19 and P/J191
■ Magenta: P/J19 and P/J192
■ Black: P/J19 and P/J193
■ Cyan: P/J19 and P/J194
2.Are the connectors securely
connected?
Go to step 6. Reconnect the
connectors.
Go to step 6.
6 Does the error still occur? Go to step 7. Complete.
7 Check the Toner Sensor Harness for
continuity.
1.Disconnect P/J Harnesses from the
MCU Board and the Print Cartridge
Sensor.
■ Yellow: P/J19 and P/J191
■ Magenta: P/J19 and P/J192
■ Black: P/J19 and P/J193
■ Cyan: P/J19 and P/J194
2. Check continuity between P/J
connectors:
■ Yellow: P/J19 <=> P/J191
■ Magenta: P/J19 <=> P/J192
■ Black: P/J19 <=> P/J193
■ Cyan: P/J19 <=> P/J194
Go to step 8. Replace the
Toner Sensor
Harness.
8 Check the Print Cartridge Sensor
signal.
1.Disconnect P/J19 from the MCU
Board.
2.Is there +3.3 V across the Toner
Sensor Harness?
■ Yellow: J19-1 pin <=> J19-2 pin
■ Magenta: J19-4 pin <=> J19-5 pin
■ Black: J19-7 pin <=> J19-8 pin
■ Cyan: J19-10 pin <=> J19-11 pin
Go to step 9. Replace the
MCU Board
(page 8-88).
