C454e with DF701 2nd side scanning issue

[Taminol]

Hi Guys,

A little guidance needed please.

We have a client with a C454e and dual scanner (DF701 I think). Please see attached quality issue, only ever on the 2nd side when using the DF.Dodgy 2nd side.pdf Please look at page 2
Initially I though this was the CIS, so I changed it, fault went away for 3 days.
Fault back, same as before, spoke with KM, they said symptom was synonymous with CIS and cable being faulty. We didn't have a cable in stock so I took a working DF701 from a showroom printer and fitted this to the clients C454e. The fault went away, this time for 2 days. Fault came back, spoke with KM, they suggested that the DF I fitted was probably a pre-modified, so it would have had the old style CIS cable. I wasn't convinced, but they are the manufacturer, so ordered a cable.
Went back there today, fitted the cable and guess what......3 hours later the same fault came back.
It can't be the DF, but other than reseating all the connectors on the PWB I'm at a bit of a loss.

Any ideas?
Thanks

Did you try to upgrade the firmware? I can only imagine some weird machine/DF FW combo since it's so cruel to have that exact fault to happen with two DFs in that short time. Strange thing that fault goes away and come back, though. Good luck.

P.S.
It also may be the machine itself(main board) and cables to connect DF.

Do you have any error codes logged?

I had had something similar and it turned out to be the dual scan board.

Might be worth a try.

Did you swap the dual scan board when you swapped DF? If not, try it.

Thanks for your replies.

The FW is current.
No codes recorded.
I like the idea of swapping the DSIPB (Dual Scanner Board). Will do this on Monday and let you know - thanks

silly question, the scan shows the front side of the meter sheet as page 2? you scanned it 2nd side up in the feeder?

Yeah, I scanned it the wrong way up.
Knew someone would pick me up on that!

With the issue happening on two different feeders, plus a new cable, my guess would be the Dual Scan Board. If not then MFP board could be at fault.

I had a similar problem to yours a few years ago and KM recommended the following procedure and it fixed it.
1, Back up machine and customer information.
2. Uninstall the HDD (SYSTEM 2)
3. Format the SSD (logical format)(state confirmation, memory HDD adjust, scroll to pg 2, SSD format, logical).
4. Clear all data (System1, initialization, clear all data)
5. Reinstall the HDD and do a logical format.
6. You will have to install movie data and import the saved settings back to the machine.
