ISSUE: Error Code E074-000
GRID: "Hi Bluto,
You are correct the E074 is related to the ITB unit.
If the machine is a high volume machine the main drive assembly would be the next item to replace.
Before replacing any more parts check with the customer to see if the copier has a history of rebooting on its own.
Rebooting on its own can cause the E074 code but it has nothing to do with the ITB assembly.
What happens is the ITB primary transfer rollers changes position during a normal shutdown cycle. If the copier abruptly shuts off, the ITB primary transfer rollers did not shift into the correct position.
On the next boot up it gives the E074 code. The shutdown is caused by a bad HDD or the main controller."
STEPS:
1. Replace ITB Unit
2. Main Drive Assembly
3. HDD
4. Main Controller
