Error Messages and Codes
DTB Life Over/Transfer Life
Applicable Chain Link
■ 094-330: Transfer Unit is at end of life.
Initial Actions
■ Ensure the Transfer Unit is installed correctly.
■ Cycle printer power.
■ If problem persists, follow the procedure below.
4 Check the connections between the
MCU Board and Transfer Unit.
Are both P/J28 and P/J281 connected
correctly?
Go to step 6. Reconnect P/
J28 and/or P/
J281 correctly,
then go to step
5.
5 Does the error still occur when the
power is turned OFF and ON?
Go to step 6. Complete
6 Check the Left Side Harness for
continuity
1.Disconnect J281 from the Transfer
Unit.
2.Disconnect J28 from the MCU
Board.
Is each cable of J281 <=> J28
continuous?
Go to step 7. Replace the
Feeder Assy
(page 8-25) or
Left Side
Harness Assy
(page 8-26).
7 Check the power to the ADC Sensor
1.Disconnect J28 from the MCU
