■ Black CRU Sensor (page 4-34)
■ Cyan CRU Sensor (page 4-35)
2.Does the number on the Control
Panel increase by 1 when the Print
Cartridge is reseated?
Replace the
MCU Board
(
page 8-86).
Go to step 5.
5 1. Check the Toner Sensor wiring
harness connectors between the
Print Cartridge Sensor and the MCU
Board.

■ 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.

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?
