MPC305 with SC899 at power up

[ricmartinho]

Hello!

We have this MPC305 (with NDD Print installed) that issues SC899 at power up, 2 seconds before the Printer icon appears on the screen. It happens roughly 70% of the times the machine is powered up. On SP7403 the detail points to Fax as you can see in the photo. This client isn't using the Fax.

If the machine is powered up and the error doesn't appear, it works ok.

This is what I've done:
- Updated all FW
- Uninstall Java and HDD
- Uninstall Fax
- Replaced Controller
- Ckecked all connectors on the BICU
- NVRAM Clear
- Downgraded FCU, FAX, RFAX and System Copy
- Updated all FW again
- Disabled DHCP
- I reinstalled Java, HDD and NDD Print.

SC899 has appeared at least one time after trying all this steps.

Our next step is to replace the BICU. Any other thoughts on this one?

Thanks

If I recall correctly, I had a B079 that was frequently giving the same sc code, but ONLY while on the network. It turned out that the machine was receiving a print command it could not process (Like sending a postcript command to a machine without postscript). A clear of the server queue took care of the issue.

Have you tried turning on your computer without the network cable in place?
All the SC899 that I have encountered were file problems sent by the user, but this is solved by updating the firmware.


You can try making a Memory Clear from SP Mode.

locate the print job that is failing and delete

Have you tried removing the fax board? I know you said you uninstalled the fax, but I don't know if that means you removed the fax board?

Let's try not to do this.

Same experience in that it is usually a print job printed off of a website that has some sort of advertising animation that the copier cannot process. Will it come to ready and be stable with the network cable unplugged? If so, as mentioned, find and delete the problem print job. You can also turn on user authentication long enough for the machine to dump the offending job. That way you do not have to seek it out in a larger network.

All the steps I mentioned were done with the network cable unplugged.

I did that.

Mikadonovan I always do a NVRAM backup.


Today we replaced the BICU and NVRAM from the BICU.
For now the machine is working. Lets see what happens tomorrow morning when the customer powers the machine.

I'll keep you guys posted.

My colleague recently had a very similar one & in his case as soon as he replaced a controller board, the SC899 went away.

hope this help you
