irAdvance 6075 unit with E748-9000 non-clearable code

[Techead42]

I'm working with one of my techs on this machine; new install, worked during setup, and at power up (after splash screens) machine codes out with E748-9000. Service manual lists this as a "System Error; see sales company". Tech has tried new Controller 1 PCB with no sucess, swapped out ROM as well, no change. Has anyone experienced this error code in the field?

This is the only thing that I have on that error:

An E748-9000 is a Communication / Mismatch issue with the TPM PCB

Problem :
An E748-9000 occurs when there is a communication or mismatch issue with the TPM PCB.

In this instance, Main Controller 1 was replaced with one from another machine. The TPM pcbs were exchanged between the main controllers before installation. The replacement main controller was left in the machine and original TPM installed with no resolve.

Solution :
Exchanging the TPM and FLASH ROM pcbs as a set between the two controllers resolved this issue

That's interesting, did the machine have TPM enabled?

did you get anywhere with this one. I was curious to know what you found was wrong.

We attempted to swap the TPM and Flash PcB's but it made no difference...we then replaced both Main Controler 1 and 2 and installed the new TPM and Flash on these but no change.

We've since pulled the unit and are working with our product support on this...will update when a resolution is found.

It's not the same exact code, but it's worth a shot to go into Level 3 and Copier>Function>Clear>E346 Error. The Main PCB Controller boards are NOT interchangeable amongst the series. 6055, 6065 and 6075 have different part numbers.

I would not clear that code E346

Flash Board
FM3-9204-000 and the part description is SATA-FLASH PCB ASS'Y.

Take note that this part is matched to the serial number of the machine it is installed in and can not be moved to a different machine.

How to access level 3 service mode?
