Re: MP3353 sc672-11

Hi all,

As mentioned above.

I have seen this exact error on a MPC2503, 3003, 3503 and 6003. The issue in most of these cases was caused by the USB cable that runs from the OPS panel to the IPU. If you disconnect the usb end that plugs into the IPU and power on the device; get your multimeter and touch the frame with one connector and with the other touch the two little openings on the connector head. If it is shorting out you will get continuity on both. It should only have continuity on one of the holes not both. This then blows a tiny fuse on the ipu, just to the right of the connector. The real trick to this issue is that you fit a new ipu and still get the same error code as the board blows again. Wild goose chase. I believe the cables may be to tightly crimped in place. FYI you can purchase the usb cable from most electronic stores just a standard cable which costs next to nothing.

We have also been experiencing this on a number of the machines you mentioned in our area.

Can you confirm whether it's just the USB cable that needs to be replaced/rerouted, or does the USB cable cause an issue with the IPU which then then needs to be replaced also?

Thanks

Re: MP3353 sc672-11

I got the same problem on a 5503. I just ordered a controller and control panel. Sometimes my machine will come to ready but only the touch screen works, none of the hard keys work. So hopefully its the panel. Anybody got any other info on this. Thanks in advance

Are the sc672's you guys are getting intermittent codes or permanently displayed until resolved by replacing/reseating cable or board?

Re: MP3353 sc672-11

Two machines would pop the message at least once a day. On/off makes it go away. The others stuck on 672-11.

Re: MP3353 sc672-11

We had an out of the box MPC4503 that threw the code upon intial startup. After reseeding all the connectors everything was fine. Definitely try that before ordering boards.

Re: MP3353 sc672-11

I have heard that a firmware upgrade can help with this fault we have had this on more than one machine each time it has been a different fix ie cont board bicu opps panel this is a nightmare to pin down

Re: MP3353 sc672-11

I have had this issue many times across the range.

I have found (as stated) in previous threads that the factory is cable tying the USB cable and harness way too tight causing this issue.

I have found the way to resolve this issue is to replace the controller board and USB cable as a set. A USB cable which is 1 metre long will do.

If you can not get your hands on a USB cable or controller board quickly, set SP1-191 to 0 (I think) or vice verca.

What this does is it does not let the controller board go into energy saver mode, while the device will, the board will stay active. This will help mask the issue but it is not a long term fix.

Ultimately I have not just tried to replace the USB cable on its self, but I will next time I get the issue.

Dear Imprestik, Thanks for the reply

I think you are referent to USB printer cable, This machine was used as network printer

If you can not get your hands on a USB cable or controller board quickly, set SP1-191 to 0 (I think) or vice verca.

Unfortunately the machine can not get the SP mode
